Product Description

Aggressive ROUSH Styling
Enhance the styling and performance of your 13-14 Mustang 5.0 Coyote with the addition of the Roush Rear Valance & Axle Back Exhaust kit. This kit includes a Roush rear valance and a Roush Axle Back with square tips to give you both an aggressive new look and a throaty, louder exhaust tone. These high quality products are put together in this kit for an easy bolt on installation!

Roush Rear Valance
Add aggressive styling to the rear of your Ford Mustang with the ROUSH® 2013-2014 Mustang Rear Valance. This valance fits 2013-2014 Ford Mustangs with the Roush exhaust (V8 Part # 421410 / V6 Part # 421517). This part comes unpainted with a grain texture that resists chipping from impacts from rocks while driving. The ROUSH Rear Valance is made from high-strength TPO (thermal plastic olefin) for long lasting durability, and is made in the U.S.A. at ROUSH's own plastics manufacturing facility. The plastic is molded with high-pressure injection, the same process used by the automotive manufactures. This Mustang Valance kit is designed around original manufacturer CAD data for optimum quality and fit. All required mounting hardware is included.

Roush Axle Back Kit
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.
