Product Overview

ROUSH 409SS Axle-Back Exhaust 05-10 GT/GT500

Completely redesigned for maximum performance, the ROUSH Extreme Mustang GT Exhaust gives your 4.6L V8 equipped Fifth gen a more aggressive growl.The Extreme exhaust uses 409 aluminized stainless steel for its durability and corrosion resistance. Fully mandrel bent pipes extend from the axle to 4 inch chrome dual wall tips with minimal flow restriction. The previous Extreme exhausts versions mufflers have been replaced with straight-through high-flow resonators. The straight through design is less restrictive and gives this exhaust a tough, guttural sound unique to ROUSH exhausts that lets people know you are driving something special. The Dual wall tips are the same design found on ROUSH 2015 Mustang exhausts, use 304 stainless steel construction and feature a special chrome flashing process that reduces cracking and heat discoloration. 

This kit uses all stock mounting points and comes with hangars pre-welded. Absolutely no cutting or custom fabrication is required for a perfect fit. All ROUSH exhausts use CAD data from the original manufacturer in the design process. This ensures perfect, OEM quality fitment and painless installation.
