MOTOBLUE™ 5-INCH STAINLESS STEEL HARD-CORE™ EXHAUST SYSTEM

1994-2009 DODGE CUMMINS TURBO DIESEL, all models, all wheelbases

How is RPM Outlet able to offer such low prices on diesel exhaust systems?

The answer is simple. We have removed the middle man and their price mark ups. We eliminate those companies who re-box the same exhaust system under their own name, and then charge up to 150% more for the same product. The MOTOBLUE line is the same 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 MOTOBLUEHARD-CORE 5-INCH EXHAUST SYSTEM is engineered to give you improved acceleration, and 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.
