turbo cars can use that less pressure. it really depends on many factors thatll determine how much youll gain. in most cases, it really is a big bottleneck. imo, its best to just get a high-flow cat. in most cases, gas mileage also goes down.

btw, it does stink. smells like a lawnmower to me.

also, im running a full mandrel cat-less exhaust.
