My car didn't have forced induction but with E/L shorties, a catted X, and open flow drag mufflers that thing sounded like a monster but seemed to loose a bit of torque. Sure I suppose I got some horses out of my exhaust swap but it felt like it being so open I may have lost a good deal of back-pressure which prolly caused my low end torque to suffer. I'm sure you need a better flowing exhaust to help that baby breath since yours is S/C so would recommend maybe X or ProChamber with good flowing mufflers. Do you plan on going the offroad route? What about headers?
