Custom/Bespoke Exhausts

[Sudesh]

I have a spare exhaust on the shelf so decided to talk to a company based here about making an exhaust for the NSX. They are Custom/Bespoke exhaust specialists and come recommended by a quite few people I know. So just wondering from the exhaust gurus on the site as to what are the do's and don't of this sort of thing?

[nobby]

nice one mate

hopefully if i can get a car ... more of us are able to make of services like this over here

as always great to read and see about the hard work you put in about these cars

[Sudesh]

Many Thanks!

Just thought I would have a venture into it and see how it goes. I know after market exhausts can be purchased from other places but wondered if we could get a quality system made that didn't cost big £££ and obviously beings bespoke the sound and exhaust tips etc can be made to suit peoples needs.

I'm not a guru but it would be good to make one that avoided boom in the cabin at 2000rpm, is durable, lighter, and most importantly, gives more power. Cost isn't such an issue IMO

[Sudesh]

Noel, I'm just working on the back box at the moment, don't think there would be any added power without a header upgrade. With going the bespoke route, once the guys get the template, from what I can gather it would mean customers can choose the sound. The exhausts are made from polished stainless steel.

Noel, I'm just working on the back box at the moment, don't think there would be any added power without a header upgrade.

Any logical, half descent design would make more power than the standard rear box. Separate silencers for each cylinder bank is the most logical design, like Taitec JGTC, Larini, Dali RR etc should add 10-15hp to either a 3.0Ltr or 3.2Ltr.

This is pretty much what the Larini guys did and indeed what Paul (Senninha) had made for him by Haywood & Scott. There's no question that this type of design makes good power but it makes a rather baritone, flat blare sort of sound. It's not unpleasant though.

After fitting, the car also sounds like it revs lower to me and you lose some of the lovely top end induction howl because its drown out by the exhaust.

Mark don't forget exhausts release power, not make it. :)

Sudesh is really a trial and error thing mate, I think since exhaust are so subjective, is kind of hard to advice.

Make sure that you start with a big box/boxes, if not happy then get them to chop them and add pipe, and so on and so forth.

I went through this and spend lots of money, made a system only to be beaten to the finish line by the Crapini booming exhaust that sold for £ 400 beans.

No quality stainless exhaust can be made for that money.

Most owners do not even consider an exhaust until the OEM falls appart, then they either want a brand name and pay thousands for it, or buy a Crapini cheap and cheerful.

I could not be bothered with loosing money on an exhaust enterprise. perhaps times have changed, but I been there done that and it was painful.

PS A good flowing exhaust can liberate around 10BHP.

[AR]

PS Tell them you want T316 stainless.

Free flowing backboxes don't necessarily make power. In fact, the loud Supersprint on my CSL gave less power. The best gain was removing the cats and silencers before the backbox.

IMO, the GT Rom exhausts are easily the best sounding for the NSX, so would love a replica of that now they are out of business. I do believe they are deliberately restrictive in order to perform the Ferrari-esque wail and gurgle on the overrun though.

[TheSebringOne]

Sudesh, it would be interesting to see what the finish article looks, sounds and perform like in terms of BHP gains. I'm still deciding on & off about changing my oem set up.

No exhaust "makes" power guys please!!!

GT Ron v1 and v2 similart to the Dali one Sudesh posted are in a way very similar and do release power. Do not forget about scavenging, resonance turbulence, velocity, flow and exhaust pulse.

Something that happens is that the way the power is delivered might be different, in other words move the tq higher up.

[NoelWatson]

Here was mine standard and with the Procar intake and GTLW exhaust

http://www.nsxcb.co.uk/testvb/attachment.php?attachmentid=4540&d=1222372306

[AR]

Very similar to this graph from SOS on the GTLW:

http://www.scienceofspeed.com/products/exhaust_airflow_products/NSX/TAITEC/GT_Lightweight_Exhaust/7b07a444.jpg

If you take the cats out you will notice what I meant about TQ.

Also the OEM manifolds even the SS are not the same as headers in flow.

[markc]

Yes exactly.

Possible but unsual, free flowing IS good.

Are you saying that changing the back box after removing the cats and pre back box silencers lsot power?

Indeed, my Dali RR system makes bigger gains, pro-rata, in the mid range than at the top end.

The term "header" is of course just what our American cousins refer to tubular exhaust manifolds as :)

Cheers

Mark

[AR]

I know they are the same but on NSX speak people normally call the OEM manifolds manifolds and the aftermarket manifolds headers.

We can call them extractors too to add more confusion to the mix.:)

The problem is that your GTLW's piping is too thin as in the wall thickness and the box quite small.

On some Yacths a thermal/sound insulation jacket is used to wrap the mufflers/ exhaust pipes. It decreases resonance You might be able to find one of this at a marine store. and customize it to your car. Not very good if you drive it when is wet as it might trap some water, but it will absorb a lot of resonance.

Here is something similar:

As an aside to people on here - what would people prioritise on buying a new exhaust system:-

- Sound?
- Power?

i.e. would you rather have an extra 15bhp but lose either some top-end induction wail or get some low-mid-rev boominess. Or would you rather get an engine that sounds better than OE but doesn't really deliver any extra power???

Why settle when you can have both?

Gruppe M is really that good, but can be improved a tad. I done it and it is high pitched up to and V8 sound on iddle. You can still hear the induction.

The GT One 5.1 loose between 5 to 7 bhp to something like the Dali/ARK DT S/ GT One V1,V2.

As I said before you won't find one that make less power than the standard Honda item so just select the sound you prefer.

The cutaway pics attached show why the Honda one is poor.


The GT One 5.1 loose between 5 to 7 bhp to something like the Dali/ARK DT S/ GT One V1,V2.

The GT One 5.1 may be a few hp down on the very highest performing ones, I don't think it's as much at 7hp, but it still makes about 10hp more that the standard one.

Missed this. Why does T316 help? It signifies the mix of additives in the stainless steel right? What makes T316 more suited to exhaust applications than T304?

Yes, that's the similar baritone blare to the Dali, Taitec, Larini, Ark et al. Nice but no longer my preference.

"Improved durability", that would be improved resistance to pitting from salt etc. Nothing to do with the sound quality or weight though.

Depends if T316 costs much more than T304 or not. If it's pretty much the same price then yes go for T316 but if it's significantly more expensive then there's not much point... unless you doing all your mileage on salty roads of course.

Cheers

[AR]

Mark it was only around 10% more. I just think is piece of mind, I have seen some awfully corroded SS exhaust, HKS being one of the worse, it must be 409 steel!

[gumball]

Anyone deal with NSXforever?/ they seem very keenly priced but how much is import tax now on something heavy like headers and exhaust?

[Sudesh]

I havent used them yet but been on the site for a look a few times. Prices of the NSX-R seats are cheap compared to what a UK dealers sells them for.

I actually received an exhaust and other bits in the one box from the US for ED's NSX when I was doing a refresh, I'll ask him about the duty etc. The only amount I recall ED paying for the bits was around £75.00 when the landed here.

Still more than I can afford :o , Honda price must be pretty steep.

[TheSebringOne]

Would it be cheaper to get a Taitech exhaust from SOS (US) or NSXFOREVER (Japan)? Thats including the exhaust, plus shipping and charges at customs, ie VAT and duties?

My exhaust was going to be around £ 700 but people prefered the Crapini.

Way cheaper than SOS and lifetime warranty plu free install.

Go figure!

[A.S. Motorsport]

when making a custom exhaust it's important to remember not to go to loud better to quite than loud.

It's a mistake often made, Loud sounds like fun but after a road trip you can literally get a headache.

Also be sure it doesn't start droning at certain RPM.

[AR]

Yes it took about 5 exhausts before I was happy and that is without counting the aftermarket ones!!!

[NSXGB]

What is your current favourite AR?

[Senninha]

Thats why I like mine ... nice a diluted when entering villages or passing through town so as not to attract the 'wrong' attention. At m'way cruising speeds it again does not intrude. Then when you want to play it offers a strong throaty noise befitting of the NSX ... add to this that it works well and releases extra ponies it smiles all round :)

Oh yes, it was a bargain compared to some recent prices costing around £600 :thumbsup:

That's exactly how i prefer my exhausts as well.

Are you guys making them from universal parts and dampers or completely custom?

[Sudesh]

The one I'm looking at will be complete custom and thinks Pauls is too.

If I remember correctly Stephen had that box shortened, or was it you Paul?

The one I have had manufactured are are full custom.

My current favourite is my Gruppe M apparently is out of production. Mine has 3k miles so is fully broken in and it sounds well... is gruppe M.

My custom one is every bit as good but 2K cheaper and unlike many Japanese and Italian ones, it fits first time.

[TheSebringOne]

Sudesh, let me know how you get on with your exhaust search. Pauls is by H & S in the London area and could be cat back system. I think his is the only one they made for a NSX?

[Sudesh]

A friend of mine has one of these and I think the exhaust note is one of the best I've ever heard, he also has a F430 which doesn't sound as good lol

[Sudesh]

Here it is along with his F430

[Senninha]

The system was bespoke for the car, and yes the box was reduced in size. This was more for accoustics but has benefitted the performance.

Its a CAT back system but is now linked via the high flow sport CATS and the whole system breathes through the over-sized Procar intake.

H&S has produced one other system that I know off. It was a stock box and single tail pipes. If it helps narrow down the owner, its on a Red/Black coupe ;)

regards, Paul

[TheSebringOne]

Sudesh, I can't believe how compact the NSX is next the others, especially the width of the F430 & the bulkyness of the GT.

The GTs sounds lovely!

[Sudesh]

Yeah quite a few picked up on that from the events we did here. Still the lowest car of the bunch, even when my friend gallardo showed up.

The Granturismo S, is by far the best sound out of the lot. Everywhere that car went on our meets, everyone just gathered to hear it. The standard Granturismo doesn't sound anything like the S. As a big proper 4 seater coupe, its top of the list in my opinion at the moment and really considering going for one.

How noisy is the Gruppe M when de-catted?
My Larini is a bit noisy for my taste (decat) and I think I would prefer a higher pitch...the Larini is definitely a baritone.
Would it not be easy enough to copy the Gruppe M??

[TheSebringOne]

Apparently residuals are very good at the moment for the GTS, in the trade they are holding value very well in this climate, also limited availability too.

It would be easy to copy something similar, but as I said, it took me several goes to get something "similar".

I am convinced that the packaging material, perforated tube insert and the hardness of the stainless have a lot to do with sound.

The GruppeM is only loud above 3 to 3,5 K. Below that all I can hear are sucking sounds and gears turning. :) After 4800 all hell brakes loose. I do have to turn down the windows if I wan to hear it. I can still hear the stereo even in a Tunnel. It seems that the sound is somehow projected out and to the back, rather than the sides.

Yeah the exhaust sound tends to be for others benefit(without tunnels)
Maybe individual throttle bodies? :laugh:

ITB's always sound great certainly on a NSX although most people have no performance based need for them this would only benefit highly tuned engines.

That's one of my favourite youtube NSX videos.

As you say poor quality vid but that one doesn't sound as nice as the previous one, just plain loud really and not unlike straight pipes. Could be the sound recording "clipping" though.

I maintain that you can't get the high pitch sound from a 90 degree V6 engine without some auxilliary piping to "fill-in" the missing pulses that make up the pitch/frequency required.

Here's possibly THE best sounding 90degree V6 ever... http://www.youtube.com/watch?v=7s8ydSTj7bo It still can't manage the scream though :)

Well that's quite relative i find personally certainly compared to others that it's worth the 1.000 pounds.

But often you can have a exhaust fabricated cheaper than a bolt on one costs.

Not only that but also the fact that most Taitec exhausts except the GT 102 are "Dronemeisters", and if anything goes wrong with them then one is left out in the cold.

[A.S. Motorsport]

Not only that but also the fact that most Taitec exhausts except the GT 102 are "Dronemeisters", and if anything goes wrong with them then one is left out in the cold.

Only exhausts with warranty would then indeed be custom made if you find a willing company.

Other good exhausts would be quite pricey for example a GruppeM.
CT Engineering also makes a very nice system but it's very quiet unless you have a Supercharger or aggressive header and test pipe setup.

I do know a very good exhaust specialist over here he used to work at akrapovic as a exhaust designer he also made F1 exhausts. Pricing is also quite reasonable.

Not bad but they were $750 when they came out, and the Stainless, well is not very Stainless.

They are also good, not the best but value for money.

The Taitec FN09 looks exactly the same as the GT-ONE Ver6 their latest version which is meant to be a big improvement over the 5.1 in terms of performance.

As a cheap alternative there is a guy doing copys in the US called Pride however the bends don't look as smooth. I think it's important with this style of system to make sure your getting a good brand to ensure maximum performance gains. Shame my 300 system wouldnt fit lol. Labree :D. That was the best of the best for the 300zx. Still sitting in my garage brand new and boxed :O yikes...

This is a interesting post as i am currently looking into exhausts. Considered single exit, side exit, Taitec GTLW and the GTTC or what ever it's called. I wanted something reasonably prices as in about 6 months time i want to go turbo which means new system. I wanted something with a good sound and great performance. However how much i look at these exhausts i keep going back to the FN09 and the GT-ONE ver6 purely for the sound. The Gruppe M ver3 is meant to sound similar but is discontinued. Maybe buy the FN09 and sell later down the line or re look at my orig idea and perhaps consider ITB's or SC which would mean loosing the targa storage which sucks! Catch 22 lol.



Gumball, Have you found a good youtube link to the GruppeM (what model/version).

I haven't found any clips that convince me that it gives the same scream that the FN09/GT One 5.1/Bel Canto etc ones do.

Cheers

I think Ary and Amo are the men for your answer!

[AR]

I forgot which # exhaust I am on!!! Well I am working on a new system for the NSX, emissions complaint and high pitch, yet civilized and no drone issues. It should be ready in a few weeks. I was ready to go last week but I wanted a slight change in the system and now have to test it all over again!!!

I remember seeing Amo's car a few years back. That was before i was thinking of getting a NSX.

I remember he was forced induction but can't remember if it was turbo or sc.

What system has he got?

[AR]

System as in Exhaust or FI?

Hi Ary, have you ever heard of Aero Exhausts. I believe they are an American system used for NASCAR?
There is a guy in Lincoln who builds bespoke systems for cars and I was wondering if you had heard anything about then.

Thanks Ian

Just curious if there are any updates on the exhaust system you was having made.

[AR]

Yes actually tomorrow I am sorting out the final version and price etc.
