4" Turbo-Back Exhaust System - SS409 w/o Muffler ('99-'03)

MBRP's 4" turbo-back stainless steel exhaust system is the best stainless 4" system on the market. Coming in at a great price this exhaust is best for anyone who lives in an area where rust is common, or anyone who is just looking for a more durable exhaust system that will outlast the cheaper aluminum options. This is a complete system, bolting directly from the turbo and featuring a rear single side exit. This is a mufflerless system which provides the most backpressure reduction and therefore best performance gains.

This is a great exhaust for anyone who wants a sturdier stainless steel exhaust system at a great price. It offers some of the best quality and performance on the market. Our 7.3L shop truck runs the aluminum version of this exhaust but if we were to do it all over we would get this stainless steel system for its durability.

This exhaust fits all 1999-2003 F250 and F350 trucks with the 7.3L Powerstroke. It is a direct bolt-on fit.
