Diamond Eye 5 Inch Alum. Cat Back Exhaust for 2004.5-2007 Dodge Cummins

How is RPM Outlet able to offer such low prices on 2004.5-2007 Dodge Cummins diesel exhaust systems?


The answer is simple. We have removed the middle man and their price mark ups. We eliminate wholesale distributors who sell the same exhaust system for a small profit going direct to the manufacturer. The MOTOBLUE / DIAMOND EYE line is the same 2004.5-2007 Dodge Ram Cummins 5″ aluminized single exit cat back exhaust system without the middleman mark up. This is a true factory direct exhaust system, which keeps our pricing extremely low for our customers.


The MotoBlue / Diamond Eye 5 Inch aluminized cat back exhaust systems are engineered to give you improved acceleration, maximum hill-climbing towing, and passing power. This is the only system heavy duty enough for off road use. The side exit location makes this the ideal choice if you pull a trailer with your diesel.
