MBRP 04.5+ 5.9L Cummins 409 Stainless 4" Cat-Back Exhaust System [MBRS6108409]

The new Cummins "600" is another improvement from Dodge that we have made just a little bit better. Dodge has recognized the value of a 4" downpipe. The new "600" comes with a factory 4" downpipe and a 4" catalytic converter. For this reason, we have designed our new systems to allow you to keep the stock converter in place for a legal exhaust system. Our 4" catback systems give you the benefit of high flow performance, a cooler running temperature and give the truck a sound that tells everyone you have the new Cummins "600". Fits 2006 Mega Cab.

Pick up where Dodge left off. Bolt this to the stock cat and watch your EGTs drop and your performance soar. Of course, we can't forget the one of a kind, unmistakable sound that big Cummins will make with an MBRPinc exhaust strapped on.
