Info on prospeed high flow cats

[FunkyNSX]

Hi guys,
I heard a few of you UK chaps orded some prospeed high flow cats on a group buy a few years ago.
Has anyone got any feedback on these cats and how they performed?
Cheers
Ben

They didn't work on 02+ cars

did they work on NA1 cars then?

I believe the 02+ LEV cars had trouble (?) but NA1 & earlier NA2 cars were ok. I believe Senninha has some on his NA2 which work without throwing fault codes. Hagasan also has some on his NA1. I have some but never got round to fitting them, standard cats are back on mine - don't want it any louder!

would u be willing to part with, if you no longer require them? ;)

Yes, been running these without ussue fir 3yrs or more now, perfect fit, complemented other changes, however as above, not for the later cars, but appear fine for all na1 na2 pre facelift
