  DYNO PROVEN TO PROVIDE THE LARGEST POWER GAINS FOR THE 2001-09 GM DURAMAX TURBO DIESEL
RPM OUTLET.COMSTRATEGY

In keeping with our goal of providing our customers with the best possible value, we have tested a large group of components specifically designed for the GM Duramax.

We have invested many hours evaluating and refining each of the GM Duramax products on our chassis “dyno”, to ensure that we could develop as much power as possible, as safely as possible.

The site menu on the left side of this page, lists the clear winners when it comes to “performance vs. dollar” value. Please check back often as we are always developing new ways to create more horsepower.

MOTOBLUE™ 4" SINGLE EXHAUST SYSTEMS
94-09, 6.6L Duramax diesel Pick-Up, all models, all wheelbases

(Dual exhaust systems listed below on this page)

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 MOTOBLUE™ STAINLESS and ALUMINIZED STEEL 280 SERIES EXHAUST 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, have a camper shell on your diesel.
