Description
Moderate to Aggressive Sound. Wake up whatever is under the hood of your massive GMC Sierra 1500 with the installation of the Flowmaster FlowFX Dual Exhaust System with Black Tips; Middle Side Exit. Your factory exhaust will sound tame and anemic in comparison with this one, which will graduate your truck to a deep, racing-inspired roar when you pound the throttle.
Boosts Power and Performance. This cat-back is primed for getting the most out of your GMC Sierra 1500’s 5.3L EcoTec3 V8—thanks to the vastly improved exhaust flow. You will feel the difference in the boosted rear-wheel horsepower and torque as you conquer 1 trail after the other.
Sturdy Stainless-Steel Construction. This system is made from mandrel-bent 409S-grade stainless steel tubing measuring 2.50 inches in diameter and brushed for a slightly rugged look. Included are dual “straight-through” mufflers with huge 4.0-inch 304 stainless-steel tips in a cool black ceramic finish. As a result, it will be hard to break down, fade, or rust with the passage of time.
Direct Bolt-On Installation. Flowmaster engineered this cat-back exhaust to directly bolt onto the factory piping without any need for cutting, drilling, or special tools. This straightforward installation will take about 2 hours of your time.
Lifetime Manufacturer’s Warranty. Flowmaster warranties that this cat-back exhaust system will be free from defects in materials and workmanship for as long as it is on the vehicle that it was originally installed. Some exclusions or limitations may apply; please see manufacturer’s warranty for complete details.
Application. This Flowmaster FlowFX Dual Exhaust System with Black Tips; Middle Side Exit is designed to fit the 2014–2018 5.3L GMC Sierra 1500s.
