4" SS Downpipe Back Single No Muffler | 2011-2016 GM 2500/3500 6.6L DURAMAX

Experience the raw power and unrestricted sound of your 2011-2016 GM 6.6L LML Duramax with this 4" Stainless Steel Downpipe Back Single Exhaust. Engineered for enthusiasts who demand maximum performance and a true straight-pipe diesel growl, this "No Muffler" system is the ultimate upgrade for your LML-powered Silverado or Sierra.

Key Features:

• True Straight-Pipe Sound: By eliminating the muffler and restrictive factory components, this system delivers the most aggressive and authoritative exhaust note possible, highlighting the pure sound of the 6.6L Duramax engine.

• Maximum Exhaust Velocity: The 4-inch mandrel-bent stainless steel tubing provides a smooth, high-volume path for exhaust gases, significantly reducing backpressure and helping your turbo spool faster.

• Premium T409 Stainless Steel: Constructed from heavy-duty 16-gauge T409 stainless steel, this system is built to resist corrosion and withstand the harsh environmental conditions faced by hard-working diesel trucks.

• Drastic EGT Reduction: By streamlining the entire exhaust path from the downpipe back, this kit effectively lowers Exhaust Gas Temperatures (EGTs), which is essential for protecting your engine during heavy towing or high-performance runs.

• Precision Bolt-On Design: Specifically tailored for the 2011-2016 LML platform, featuring OE-style hangers and pre-welded contour bends to ensure a secure fit and a straightforward installation process.
