Product Description

Upgrade your Ford Mustang GT or GT500 with the Rev9 FlowMAXX Axle-Back Exhaust System and give your car a more aggressive sound, improved exhaust flow, and a true performance-inspired feel. Designed to enhance both tone and responsiveness, this system delivers a deeper, race-inspired exhaust note while maintaining a clean OEM-style fitment.

Built from high-quality mandrel-bent stainless steel piping, the FlowMAXX system is designed for durability, long-lasting performance, and smoother exhaust flow with reduced restriction. The axle-back design helps your Mustang breathe more freely, improving throttle response and giving the car a more exciting driving experience whether you're cruising around town or getting on the throttle.

Available in both high-flow muffler and straight pipe configurations, you can choose the sound level that best matches your style. The muffled version offers a deeper and more refined aggressive tone, while the straight pipe setup delivers a louder, more raw race-inspired sound with maximum exhaust flow.

To complete the look, the system features bold dual-exit 4-inch slant-cut exhaust tips that give the rear of the Mustang a more aggressive and performance-oriented appearance.

Designed as a direct bolt-on upgrade, the FlowMAXX Axle-Back Exhaust installs easily using factory mounting locations with no complicated modifications required, making it a simple and effective way to improve your Mustang’s sound, style, and overall driving experience.d
