I don't think i'm divulging any info that's not already obvious, but it's all personal preference. I think Dynomax straight-throughs outflow just about everything on the market, but I know a a lot of people that hate the way they sound. As for strictly sound? Borla XR1 mufflers are sooo nice, but pricey as hell.Fox Saleen 163 said:I have offroad X with Magnaflow's dumped. I like it. The dumps give it a deep rumble in low RPM's and it still has that pissed off X pipe sound in the high RPMs.
