Description
Performance Exhaust System. The Flowmaster FlowFX Extreme Single Exhaust System with Dump-Style Exit delivers enhanced exhaust flow and an aggressive tone for enthusiasts looking to boost their vehicle’s performance and sound. Designed specifically for off-road use, it improves both ground clearance and departure angle by eliminating the traditional over-axle tailpipe.
Construction and Appearance. Crafted from durable 409 stainless steel with 3.00-inch diameter mandrel-bent tubing, this exhaust system maximizes flow while reducing restrictions. The natural finish highlights the system’s rugged design, paired with a Flow FX series muffler that produces a distinctive aggressive absorption sound.
Installation. Installation is straightforward and uses factory hanger locations with included hardware, requiring no drilling or modifications. This allows for a secure fit and an immediate upgrade without professional assistance.
Warranty. Backed by a lifetime limited warranty for long-term peace of mind. Application. Designed exclusively for the 14-18 4.3L Silverado 1500 for a precise fit and optimal performance.
