Review on Enhance Your Vehicle's Performance with Lawson Industries 77402 INSYNERATOR High Performance Muffler by Chris Cooper
Sounds great!: Muffler
I mounted it on my 2011 Silverado with a 4.8 engine and it sounds exactly like my 5.3 with the Flowmaster 40 series, has a very clean and loud rumble! Can't beat it for less than $40
Pros
- Excellent construction
Cons
- Everything is fine
