I have been thinking about swapping out my exhaust for a full 3" setup without cat and Borla Turbo muffler. No intermediate muffler. I've had good luck with the Borla stuff in the past. Will the removal of the cat cause any issues or a CEL with my '99 9-3? O2 sensor issues? Will the aformentioned exhaust setup be too much and bog down the car?
That thing will be loud!! You should just buy the saab sport exhaust. Thats what I have on mine. I'll even help you install it if you would like. PM me if you decide to go for it, we can have us a '99 9-3 party!
