The FLO 834NM is a 4" Downpipe Back Exhaust system for the 2007.5-2010 Duramax 6.6L. It replaces your restrictive OE exhaust system from the downpipe back with a 4" mandrel-bent exhaust system, this kit does not include a muffler and is designed for race applications. Just like all of Flo-Pro's Exhaust kits, it will come with all the required clamps, pre-weld contour bent hangers, and stronger flanges to help you cruise through the installation process. This exhaust not only sounds great, but will improve your torque, mileage, and throttle response!

QUESTIONS & ANSWERS

Ask a Question

  • Whats is the difference between stainless steel and aluminum in the sound or is it about durability??

    Sound difference = minimal to none, both materials produce virtually identical exhaust tones. As for durability, stainless steel is more corrosion-resistant, ideal for harsh climates (salt, snow, moisture) and will last longer overall. Aluminized is more budget friendly, but will be prone to some spot rusting over time, especially in wet or salty environments.

  • Does this system come with cats?

    No.
