GT500 exhaust testing: O/R H pipe results on big blower car WOW
A local customer brought his car over yesterday so we could test the JBA Off Road X pipe on his Stage 3 KB GT500 (running 3 inch pulley and pump gas). Exhaust system was otherwise stock.
I could not believe the top end gain of 32RWHP. Boost dropped about .5-.75psi from 3000rpm on up.  Longtubes seem to add area under the curve everywhere, whereas this only helped above 5000RPM. I'm not big on the raspyness that no cats creates. I may try making an X pipe for my TVS GT500 that has a set of high flow cats farther away from the motor (to reduce chance of melting them). The stock X pipe has a much nicer stamped X, than the JBA pipe. Anyone have a stock cat pipe they want to get rid of?
