The latest ROUSH Performance F-150 exhaust kit not only adds throaty growl, but also stock-car-inspired styling by redirecting the exhaust gas out to the passenger side of the vehicle. The kit fits 2011-2014 5.0L-V8 and 3.5L V6 F-150, as well as the 2010-2014 6.2L-V8 F-150 SVT Raptor. “We wanted to provide a product that offered something beyond aggressive sound and the appearance upgrade that you would expect from a ROUSH exhaust kit,” says Tony Marszalek, Product Marketing Director. “With our new side exit exhaust kit, we did that by drawing inspiration from our company’s rich racing heritage.”

(1) Polished Muffler Assembly
