Description

Completely redesigned for maximum performance, the ROUSH Performance Extreme Axle-Back Exhaust gives your 2005-2010 GT or 2007-2010 GT500 a much more aggressive growl than ever before!This ROUSH Extreme Axle-Back Exhaust is constructed of 409 aluminized stainless steel piping for its durability, which is also mandrel-bent for consistent flow throughout. The system is then finished off by 304 stainless steel chrome-flashed tips (embossed with the ROUSH logo) for superior look as well as superior durability & corrosion resistance. The straight through design is much less restrictive and gives this exhaust a tough, deep sound unique to ROUSH exhausts that lets people know you are driving something that means business. Included will be all necessary hardware and instructions for installation.
