      Impressive Exhaust Sound. Equip your Sierra 1500 with a high-quality exhaust kit by upgrading to this Dynomax Ultra Flo Welded Dual Rear Exit Exhaust System with Polished Tips. This exhaust system generates deep and aggressive sound with minimal in-cab noise, thanks to Dynomax’s muffler with Continuous Roving Fiberglass Technology.

This efficient flow effectively boosts your truck’s performance. Moreover, the smooth piping minimizes blockage and backpressure, thereby ensuring sustained powerful exhaust flow.

      High-Strength Construction. Dynomax ensures long-lasting functionality of this Ultra Flo Welded Dual Exhaust System by using high-quality stainless steel tubing.

Additionally, this cat-back exhaust kit boasts of a top-notch build that maintains your truck’s tough appearance and offers a direct-fit upgrade from your stock exhaust. The 3-inch, slant-cut, mirror polished exhaust tips also give your Sierra a distinctive, elegant shine.

      Bolt-On Upgrade. Designed for a direct bolt-on installation, this Ultra Flo Welded Dual Exhaust System with Polished Tips installs directly into the factory mounting points of your vehicle.
