Review on 🔊 Lawson Industries INSYNERATOR 77753 - High-performance Big Body Muffler by Hayden Hart

All I can say is wow. The muffler is identical to the FL 50 series and sounds the same if not better. I use it on a '96 Chevy Silverado Regency rebuild. Vortec 5.7V8! I actually had the chance to speak to Jim Lawson on the phone and he said I loved it. He was right! It has a low, soft growl, like a lion's, but softer. Half the price of the FL 50. I just hope it lasts as long as the FL 50. I also added Lawson Insynerator 22x4 exhaust pipes which made the sound even better.
