Review on Enhance Your Vehicle's Performance with Lawson Industries 77402 INSYNERATOR High Performance Muffler by Daniel Steele

Sounds good. Fairly quiet at idle but makes good noise at 1500-6000 rpm. I would like a deeper and louder idle. I hope he wakes up when I remove my cat. Overall a good muffler and cheaper than the Flow Master with the same sound and quality. I put it next to my friend Flow Master 40 I think. For me not a big difference. Both on Chevrolet 5.3 2002 and 2004.
