proper exhaust size for STS autocross car
Ok, I'm tryin to figure out how much bigger, if at all, an exhaust I should go with to set my 91 CRX Si up for STS autocross racing...
STS allows just boltons. Intake, headers, exhaust. Emission controls have to remain, but they do allow a programmable ECU. So, keeping those in mind, should I go with...
a 2.00 inch exhaust from the catylitic converter back?
a 2.25 inch exhaust from the cat back?
a 2.5 inch exhaust from the cat back?
or...should I go with some custom size like a 2.1 inch?
thanks guys
