Roush 2015-2017 Ford Mustang Axle-Back Exhaust Kit with Round Tips - 304SS (5.0L) #421834
$799.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2015-2017 Ford Mustang models including GT, EcoBoost, V6, and Shelby GT350/GT350R (5.0L).
Give your S550 Mustang a more aggressive acoustic profile and improved exhaust flow with the Roush Axle-Back Exhaust Kit. This system replaces the restrictive factory mufflers with high-flow units designed to produce a deep, throaty V8 growl at idle that builds into a powerful roar under heavy acceleration. Each system is engineered to reduce backpressure, helping your engine breathe more efficiently.
Built for durability and longevity, this kit is constructed from T-304 stainless steel to resist corrosion and environmental wear. The mandrel-bent tubing ensures a constant internal diameter throughout every bend, eliminating kinks and turbulence for maximum flow velocity. The kit features polished round tips that provide a finished, performance-oriented look to the rear of your vehicle.
- Manufacturer Part Number: 421834
- Material: T-304 Stainless Steel
- Tubing Type: Mandrel-Bent for optimized flow
- Tip Style: Polished Round Single Tips
- Muffler Type: High-flow performance canisters
- Direct bolt-on installation using factory hanger locations
