I ran the mufflex 4" for a while on a cam only LS1. I picked it up used for $150. The spintech welds eventually rusted out and I got a used Borla cheap and sold the 4" tubing.
The difference in bottom end performance was noticable and improved for the better when I dropped to a 3". Can't say I really noticed a difference on the top end.
The other issue was the rear hitting the 4" pipe. Nothing major, just enough to make noise and annoy me. If I ran another mufflex it would be 3.5". I wish they had better mufflers to choose from, and IMO $550 is a lot to spend on an aluminized system.
