Some great quality features of this exhaust are:

• The muffler, inlet, outlet, and y-pipes are made from high-quality 409 stainless steel to prevent corrosion and enhance durability.
• The tips are constructed of high-quality 304 stainless steel that have been chrome-flashed for superior corrosion resistance and durability, and are embossed with the ROUSH logo, which exit out of the side of the vehicle.
• The piping in this system is 3” in diameter, which is all mandrel-bent to promote consistent flow throughout. Other companies tend to crimp-bend their exhaust, which can cause restrictions and inconsistent flow.

This exhaust kit is designed to work on all cab and bed configurations for the 2011-2014 5.0L, 6.2L (including SVT Raptor), & 3.5L F-150s. This includes the XL, STX, XLT, FX2, FX4, Lariat, King Ranch, SVT Raptor, Limited, SuperCrew, SuperCab, and Regular Cab models.

Please note that for 2011-2014 6.2L Platinum and Harley Davidson edition F-150s, modification to the factory exhaust flange will be required. ROUSH obtains its iconic aggressive sound on this system by deleting the restrictive factory resonator and implementing a canister-style muffler with 3” exhaust piping..

ROUSH Performance also offers a side-exit version of this exhaust system, which obtains the same sound but a slightly different look.
