Give your 2013 V8 Mustang the aggressive sound it deserves . This innovative new exhaust system from ROUSH features a hollow muffler chamber, as opposed to conventional fiberglass-packing. The result is a unique and less inhibited sound, increased air flow, and increased longevity (there is no fiberglass that will break-down with time). Another great feature of this system is the lack of the in-cockpit boom normally found with performance exhaust systems at cruising speeds.
Not only does this exhaust sound good, it looks good as well. The dual chambered tips are made from high-quality 304 stainless steel and are finished with a chrome flashing process. Their shape finishes off the contours of the Roush rear Valance. Conventional chrome plating uses layers of bonded chemicals to achieve its shiny appearance, which are susceptible to cracking and flaking especially when exposed to high temperatures (like exhaust). However, the chrome flashing used in this system is bonded micro-porously to the metal surface, and is as a result impervious to cracking from localized damage. This method of chroming is also resistant to heat color change.
***Note, 2013 Roush Rear Valance RSH-421406 is required for proper fitment.***
