XForce 3” Stainless Steel Round Cat-Back Exhaust with 4” Polished Tips for 2015, 2016, and 2017 Fastback GT Mustangs.
Upgrade your 2015-2017 Fastback GT Mustang’s performance and power with an XForce 3” Stainless Steel Round Cat-Back Exhaust with 4” Polished Tips (ES-FM15-CBS)! This kit replaces your existing exhaust system from the catalytic converter back with mandrel-bent 3” polished stainless steel tubing. The mandrel bends allow the exhaust fumes to flow without restriction, producing a mighty drive-by roar while giving your engine more space to exhale quickly.
Features and Benefits:
- Deep, aggressive exhaust note
- Improves power and performance
- 3” Polished stainless steel tubing
- Triple-muffler design
- 4” Double-wall, angle-cut exhaust tips
- Bolt-on installation
This kit uses two round rear mufflers and a center oval muffler, which eliminates the factory resonator, to further increase the exhaust note’s volume. A pair of 4” polished, double-wall, angle-cut exhaust tips complete the system and add a touch of shine and aftermarket style to your S550.
Please Note: This Will NOT Fit Convertibles or any 2018+ Models.
