i have a set of stainless cutouts on my magnaflow exhaust. there great if you want to let everyone in the state know your cruisin, but anyway im going to dyno next week. will it help any to have them open on the dyno? i do not have headers just cutouts before the muffler. my goal was sound not performance. but im wondering if it might help squeeze a little more out.
