how do dynomax mufflers compare to magnaflow? im thinking of either getting an x pipe with di/do or the dynomax ultraflow x. ive heard great things about magnaflow just havent heard much about dynomax.

I have it on my truck! I love it doesnt sound like that sound clip like I was hoping it would, but I have stock manifolds and cats unlike that guy on performance trucks. The skinny is that it is louder than a flow, probably equal to the magnaflow version of this muffler, and it almost has that bullet rasp but its nice low deep rasp sound NOT ANNOYING only inside resonance I have had was on a highway trip around 2200-2400 rpm doin like 85-90mph real deep and i like hearing it in the cab cause you know everyone else is too. under normal acceleration it has some resonance kinda sounds like a big block and at cruising speed you can barely hear it in OD unless you step on it. OVERALL I LOVE THIS MUFFLER!!! Need to post up a sound clip for you guys I have an 06' ECSB exited 45 behind the wheels 2.5 piping all the way back with 3.5" 18" long stainless tips. It took a little bit of money and convincing to get it put on cause the guy was being lazy but cost $600.00 total I'll try and get some pics of the routing the guy did and some sound!
