Roush Performance/ Kovington Exhaust System Kit

Exhaust System Kit; Extreme Axle Back System; 409 Stainless Steel; With Straight-Through Resonator; Dual Exhaust; Rear Exit; 4 Inch Chrome Dual Wall Tips

MPN: 421915

Completely redesigned for maximum performance, the ROUSH Extreme Exhaust gives your GT 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.
