6.4 Powerstroke MBRP 4" Aluminum Exhaust - No Muffler

This is a emissions-back 4" aluminum exhaust system from MBRP. At just $299 it's the best bang-for-the-buck exhaust on the market. While it isn't as durable as steel versions the aluminum has less drone at highway speeds making this the preferred option over the pricier steel versions. This larger 4" exhaust will help reduce exhaust backpressure, improving turbo efficiency leading to power gains and lower EGTs.

We highly recommend adding a 4" downpipe alongside this exhaust system. If you choose to do so we have a 4" MBRP full kit that includes the downpipe and a 4" exhaust system that includes a nice looking exhaust tip (this exhaust does not have a tip). It is $5 more expensive than purchasing this exhaust with the downpipe separately, but you save $75 over purchasing the S6242AL which includes the exhaust tip.

Whether you're looking for some extra exhaust sound, are tuned, or just looking to maximize reliability, an exhaust upgrade is a great modification to help. You will see power gains and improved reliability through lower EGTs. This is a direct bolt-on fit making for an easy install.
