I'm looking for someone that makes more or less stock diameter secondary CAT delete pipe. 1.75" or so. I built my own out of 2.25" and for my application I think I may have gone to big and as I'm short on time to build a new one I'll buy one if there is something out there.

Thanks

 

If you're talking about the resonator and b-pipe, no one really makes anything this side of the pond. I assume you mean the resonator and not the cat because both catalysts are connected on the same part.

They'll most likely have to be imported, and they're pricey AF. Spoon and J's both make B-pipes, but they're like almost a grand shipped. You're better off fabbing if you need it quickly. You can try posting the wanted ads, maybe someone's trying to get rid of theirs?

If you're looking for cat delete down pipes, RV6 discontinued theirs. I belive the next easiest to obtain is RZCrew's, which might still have to be imported.

 

I'm looking for the secondary CAT pipe (pipe A, I believe), however with no CAT, about 2 foot long attaches to the exhaust pipe which contains the primary cat.

 

2.25" is OK

 

We are running a restrictor plate on the intake so the performance of the engine is impacted. It's a B Spec car for road racing.

 

Damn.... Restrictor plate on such an OEM restricted intake.....
