Roush Extreme Cat-Back Exhaust Kit
This complete cat-back system from ROUSH performance can deliver massive horsepower and torque gains while boosting fuel economy and giving your Mustang an amazing V8 roar without an annoying cabin exhaust drone.
ROUSH's Extreme Cat-Back kit uses precise CNC bending on each of the 2.5" stainless steel tubes to get a smooth mandrel-bend that maintains the internal diameter of each tube. The smooth curves optimizes airflow and is less restrictive than the stock exhaust configuration which allows your Mustang to reach a higher power potential.
The entire system is made from T304 stainless steel and comes with 4" polished tips embossed with ROUSH's logo.
Each kit uses OEM clamps and fits the factory rear fascia. No welding or cutting is required for installation.
