Looking to obtain the iconic ROUSH exhaust sound for your F-150, but want a more ?OEM? look? 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 including the XL, STX, XLT, FX2, FX4, Lariat, King Ranch, SVT Raptor, Limited, SuperCrew, SuperCab, and Regular Cab models. 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.
