Works great on my 2002 Cummins. Bought a 4” for it just so it could be considered legal. Slight(very very slight) reduction in noise and no tone difference, but was to be expected. Would recommend this product. However, I did receive mine with one slip-on end and one weld-on end which was disheartening. Never the less, I made it work.

This product is great if your looking to pass inspection for having a muffler but yet still have a loud exhaust. I put it in a 2005 lly duramax and I didn’t notice any difference over straight pipe. Would buy again

The muffler is small and fits in tight spaces. It also provides a great deep sound to the exhaust.
