2021 Chevrolet Silverado 1500 exhaust sports  muffler.

This is a 3.5 inch stainless steel system.

The KM Chevy Silverado 1500 sports muffler replaces the factory muffler on the exhaust system. It is quick and easy to fit. 2 cuts are required to remove the stock muffler.  The KM Sports Muffler pipe is expanded on each end to slide over the cut pipes. Once in place simply tension the claps and it is ready to go.

Once fitted it gives the very cool Chev 1500 a great V8 Rumble. Its an aggressive note. For the full effect be sure to check out the Kuluin Mufflers YouTube.
