Thanks for posting that. I have been looking for an O pipe for a while but couldn't find one. They have one for $99.95 which is a little more then I wanted to spend but I guess I will have to.
Did you get the one for single or dual exhaust? Do you think the single O pipe setup would increase gas mileage in my GS?
I got the one for the dual. I don't know how big of a mileage increase you will see but you will really feel it with the power. My buddy has a 1999 GP and he has just the single O pipe and when he gets on it you can really tell. I would say you will only see about 1 MPG difference. Every car is different though.
Dang maybe I will have to reconsider getting one for the GS and get one for the trubo gp. Maybe it will increase exhaust gas velocity if I put it before the turbo?
