Roush Performance Axle-Back Exhaust Kit with Round Tips for 2015-2023 Ford Mustang (2.3L / 3.7L) 421837
$729.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2015-2023 Ford Mustang EcoBoost, V6, GT, Mach 1, and Shelby GT500 (2.3L / 3.7L).
The Roush Performance Axle-Back Exhaust system replaces restrictive factory mufflers with high-flow chambered units to provide a more aggressive exhaust note. Built from T-304 stainless steel, this kit offers superior resistance to corrosion and staining over the life of the vehicle.
Engineering features include mandrel-bent tubing to maintain consistent diameter through every turn, reducing backpressure and maximizing flow. This exhaust kit is designed as a direct bolt-on solution, utilizing factory mounting locations to eliminate the need for welding or custom fabrication during installation.
- Constructed from high-grade T-304 stainless steel
- Mandrel-bent tubing for optimized exhaust flow
- Single-tip high-flow chambered mufflers for aggressive tone
- Direct bolt-on installation using factory mounting points
- Corrosion and stain resistant finish
- Manufacturer Part Number: 421837
