Super Six install pics
Hey David, sorry i just saw this and am getting back to you so late. You know, the dual exhaust on a slant six may provide some performance improvement. But i dont race my cars so the minimal gains are not important to me. What it did do is make it sound nice when you pulled up to the valet behind the guy in the escalade.
Remember performance gains i have found tend to be relative to all the other things you do to your engine. Cam, mill the heads, dual exhaust, electronic ignition etc etc etc. You can keep on going all you want for 10hps here and 6 hps there. But if the goal is to get your car running well and to enjoy it, then you will be just fine with a single exhaust. Make sense?
Hope that helps you gain some perspective. Good luck!
