This 4-inch 6.0 Powerstroke diesel Cat-back exhaust kit comes with all the components that you need to install this stainless exhaust and muffler for any cab and bed size configuration including an 18-inch muffler, a muffler replacement, and a polished stainless steel exhaust tip with a rolled edge and proudly stamped with the Sinister Diesel logo.
