Description
Full and Powerful Exhaust Sound. With this Flowmaster FlowFX Dual Rear Exit Exhaust System, you can enjoy a more intense roar from your Sierra. As your vehicle drives down the road, the soulful guttural sound grows louder, exuding a remarkable degree of power and class without overheating the track.
Glaring Performance Buffs. This cattedexhaust system's high-flow, straight-through FlowFX muffler, and mandrel-bent tubing provide consistent exhaust discharge, significantly increasing your Sierra's motor power and torque. Even at maximum performance, this continuous flow increases fuel efficiency.
Unyielding Stainless Steel Build. This FlowFX Dual Exhaust is a great, long-lasting modification, made from polished, mandrel-bent 3-inch stainless steel tubing. The extremely corrosive exhaust chemicals and the severe heat created by the intensive catalytic activity are not a problem for 409 stainless steel. Its strong, welded muffler casing and superior tubular fabrication can endure salt, pebbles, tar, and other adverse elements.
Warranty. This product comes with a limited lifetime structural warranty that covers all damages prior to delivery. Limitations may apply to this warranty.
Installation. this product does not require professional installation and would take at least 1 hour to attach.
