A turndown will have zero effect on power. It might quiet it down a little but you probably won't even notice it. I have no idea why the hell you want your truck that loud. Glasspacks sound loud and shitty on any motor; especially a 4.3

I've got a IMCO flowmaster knock-off on my 4.3 that sorta has that has a grumbly sound to it. If you want it loud, do straight pipe out in front of the wheel that goes from 2 1/2", to 3", to 4" piping like a megaphone.

4.3's are best left quiet, my opinion.

If the 4.3 has engine work done or the exhaust is done right they actually sound pretty good. But if someone is going to hack the exhaust, have leaks everywhere put a piece of shit muffler on then yes it is better left quiet. Actually that doesn't go for just 4.3s that goes for anything. V8s can sound like shit as there are many around my area. :rolleyes:
