Give your Chevrolet Silverado/GMC Sierra 1500s exhaust system an upgrade with a DynoMax Ultra Flo welded 3-in. single cat-back exhaust system.

Hear It Logo

For the best results DynoMax highly recommends using a good set of headphones or better than built-in computer speakers. Muffler sound is all about BASS. Cell phones and built-in computer speakers will not give you the true experience of the Muffler sound.

Benefits of Purchasing an Exhaust System Kit

Replacing just a section of your exhaust system is less expensive up-front, but a complete Exhaust System Kit provides added benefits:

  • Extend Service Life: New clamps, gaskets and hangers (where applicable) prevent exhaust system leaks or damage that can occur when reusing old / incompatible hardware.
  • Reduce Install Time: All included parts are guaranteed to fit together seamlessly to ensure a smooth, problem-free installation.
  • Save Money: The cost of the complete kit is often less expensive than buying the components individually, and means you only have to do the job once.
