Description
Commanding Sound. Expect a powerfully deep exhaust tone coming from your Sierra 1500 with this Dynomax Ultra Flo Welded Dual Rear Exit Exhaust System with Polished Tips. This cat-back exhaust kit will give your truck a raw and rich exterior exhaust sound under acceleration, thanks to the Continuous Roving Fiberglass (CRF) Technology that eliminates the unwanted interior resonance.
Performance Boost. Using this Ultra Flo Welded Dual Rear Exit Exhaust System will let you experience an outstanding power boost. This reinforced performance is attributed to the efficient exhaust flow, thanks to the straight-through muffler design without restrictions and reduces backpressure. The uninterrupted exhaust flow also maximizes gas mileage even with full performance.
Long-Lasting Toughness. Crafted using premium quality stainless steel, this Ultra Flo Welded Dual Rear Exit Exhaust System exhibits superior strength and corrosion resistance. To complete this exhaust kit, a pair of mirror polished exhaust tips will accentuate your truck’s overall presence on and off-road. These polished exhaust tips will add some stylish gleam to your truck’s tough appeal.
Bolt-On Installation. Dynomax designed this Ultra Flo Welded Exhaust System to bolt directly onto your truck’s factory mounting points. It includes all the hardware and band clamps for a simple, no-drill installation that completes with light to moderate mechanical skills.
Application. This Dynomax Ultra Flo Welded Dual Rear Exit Exhaust System with Polished Tips fits all 2014 to 2018 4.3L GMC Sierra 1500 models.
