🔊 Lawson Industries INSYNERATOR 77753 - High-performance Big Body Muffler Review

Love it. Installed on Nissan Titan 2012. Good noise at idle and low revs. Quietly on the highway with no hum in the cockpit. I do real duals to make them stand out. Sounds good.

Great product, I was impressed with the value for money. I installed this on my old V-10 Ram. These engines don't always have a nice sound through the exhaust, but it sounds pretty good. Just loud enough, but not gross.

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.

Replaced a rotten OEM muffler with a 2014 Tundra 4.6L V8. It was hard to hum at first. Trimmed my exhaust pipe to reset after the last hanger just passed the rear axle. Now it's perfect. Chamber sound, similar to the Flowmaster 50 series muffler. After shortening the exhaust pipe, there is no rumble in the cabin. No rasp. Simply pure V8 sound. Combined with a K&N filter and now averages 2mpg more (average 18.4mpg). Torque is slightly higher in the powerband. Noticeable difference at highway…
