MOTOBLUE™ 5-INCH T-409 STAINLESS STEEL HARD-CORE™ EXHAUST SYSTEM

94-07 DODGE CUMMINS TURBO DIESEL, all models, all wheelbases

MOTOBLUE™ Exhaust systems are built of aircraft-quality T-409 stainless steel -- stainless inside and out, not mild steel, not aluminum, not coated aluminum, not just wrapped with stainless on the outside for show. T-409 stainless steel has a high chromium content, making it resistant to corrosion and therefore the most desirable material for a long-lasting exhaust system.

Once you have installed a MOTOBLUE™ exhaust system on your diesel powered vehicle you’ll never have to worry about the durability of your exhaust. Stainless steel hand crafted construction will take whatever you can throw at it. Each system is dyno tuned tested to ensure the best combination of torque and horsepower.
