What if I don't want to replace stock exhaust? How much can you squeeze *safely* out of an otherwise stock STI with Protune?
Yeesh...I thought cobb's off-the-shelf stg1 map was good for more than that. Is the stocker already stretched that much?
yeah you would probably have to cut a decent amount off of that with the stock cat-or axleback. I would guess, much less than the torque than rolling_trip put down, like 15-20wtq EDIT: then again...I may very well be talking out of my ass....2nd drunk post of the weekend
