i have been hearing alot of talk about exhausts expecially from dc sports...which exhaust will get you better hp gains a single exhaust or a duel exhaust? and what company is the best for the 2.0L ss s/c?

 

Dual exhaust for a 4 cylinder that pushes under 600HP is just silly. Not to mention that it would be a Ypipe, and not true dual exhaust. Also, adding another exhaust pipe will make your car sound raspy - which I, and most the members here will make fun of you for. I say go with Borla.
