For the best results we HIGHLY recommend 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.


Dynomax® Ultra Flo™ SS Polished performance mufflers are constructed of stainless steel for lifelong durability and completely polished for show-quality shine. The unrestricted, straight-through design is dyno proven to flow up to 2,000 SCFM and support up to 1,900 horsepower. Each muffler uses our exclusive Continuous Roving Fiberglass (CRF) Technology to absorb unwanted interior resonance while maintaining a deep performance tone.
