I have no idea how bad it is now so I can't say, it might tone down but your going to smell like catless, theres no way around it

I used to run spoon test pipe, apxi n1, with the CT SC w/o the AC, I never had lean issues.

But I ended up putting the CAT back in because I hated driving around always with my CEL on. Since then I've add the AC, and I recently came across the Berk test pipe in the group buy thread which claims to not cause CEL's so I bought one and is going to give it a shot this coming spring.

Maybe you could go that route if you think the CEL is causing your car to run like crap?

Everything will run perfectly fine as far as the fpr goes. The only

I'm having a comptech supercharger w/ AC installed on my 2001 honda
s2000. Aside from the SC i'm also running an aftermarket dual exhaust
and test pipe. Should I be concerned about the car possibly running
lean? Or can the included FPR handle the added air flow?

Thanks.

the CEL you get from test pipe is because the PCM thinks the Cat is not working; there is no fuel adjustment or anything from that, all that info comes from the header. To fix the CEL with the test pipe all you need to do is go to AutoZone and get 2 spark plug foulers, drill one out and then screw it into the one that is not drilled out. After that simply put your O2 sensor in there and no check engine light. All this fix does is move the O2 sensor far enough from the test pipe where it doesn
