Open headers vrs. full exhaust

Unless your build in such a way to take advantage of it you won't see a thing.

Let me clarify……

Lets say you have a 360 with a nice street strip build…….. And you already have a good exhaust system….. Like TTI headers with a 2.5" x-pipe system dumping into some free flowing mufflers…. You probably won't see much if anything.


Really… We need more info.


Electric cut outs would be nice if your system is choked down for nice quiet street driving and you want to open it up for race day.
