This system has been designed specifically for the 1999-2003 7.3 Powerstroke and offers significant gains in both power and torque. The heart of this system is the high-flow TurboChoice muffler which provides an aggressive sound without being too loud or obnoxious. This muffler is also fully welded for maximum durability and longevity.
Downstream of the muffler, we have included a 4 inch polished stainless steel piping that gives this system an incredible look as well as superior performance. All of the necessary clamps and hardware are included for a quick and easy installation.
