Installation is a Snap:

A muffler eliminator-
pipe is used for a true race-inspired sound and maximum flow.

Perfect Fit:
OE style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The Bayonet tip holds the hanger bushing in place for an OE style fit that does not change with time.

Most Popular Questions

What exhaust system and tuner will work best to meet my goals? (I am looking for ways to increase the mileage.) 2008 F250 6.4L.
View Staff Answer 

Fuel economy increases can vary between your choices in products, but it really depends on your driving habits and the conditions of your vehicle to see the best gains in MPG. Checking your air filter regularly for optimum flow, making sure tires are at the manufacturers recommended pressure, keeping your bed empty to reduce weight, avoiding wide open throttle starts from a stop, breaking early as you come to a stop, and achieving a more complete burn of fuel are some steps to help fuel economy. Achieving a more complete burn is something you’ll accomplish with the addition of a programmer, exhaust and intake regardless of the manufactures you choose.Please give us a call at 1-888-DIESEL-4 or use the LiveChat feature on our website to help you select the perfect product for your application.
