Leaving all legal issues aside.

What is the performance increase for high / low rpms in proportion?
Are the any concerns about the O2 sensor, CEL's?
Does punching out the stock cat achive the same thing?

There are gains across the board. It varies depending on cam timing, tuning, setup, etc. . . but I have seen gains in the usual 4-5 whp area most of the time with some over 12 whp if they are equipped with camshafts. You WILL have CE light though unless you use one of my test pipes or you switch ECU's.

 

I thought all our cars had camshafts?

 

Now everyone wants to be like Boba-Fett!

SMSP - Who thinks Boba-Fett is my hero

 

I can dream can't I?

 

hey, theres nothing wrong with being like me.

Boba- who's true Hero is SMSP!

 

Dan, any comparison's between stock cats that are hollowed and aftermarket testpipes? I'm not worried about CEL's either way, it's easily fixed with some resistance...
