This info can be found at Team-Integra.net in the exhaust articles. You can thank Tuan over at TI for the info.
Aftermarket High Flow Cats Versus Testpipes On A Daily Driver:
Comparing a 2.5 in. testpipe (RED) to a 2.5 in. Carsound cat (BLUE) in the same ITR ( 1.8L B18C5 ) with a CAI, Toda B cams, an SMSP 4-2-1 long hybrid header (2.5 in. OD collector), and SMSP 2.5 in. OD exhaust, Apex Power FC fuel tuning:
I never specifically stated that you would lose torque in my previous post. The numbers look to be 188.5 with the Carsound and 190 with the straight pipe, but the graph looks blurry and my vision is pretty bad.
How's that for "evidence" ?
