4" Exhaust DPF Delete Pipe for 2011-2015 Chevy Silverado GMC 6.6L LML Duramax Diesel

The DynoVox 4" Exhaust DPF Delete Pipe for 2011-2015 Chevy Silverado and GMC 6.6L LML Duramax Diesel is designed to replace the restrictive Diesel Particulate Filter (DPF), improving exhaust flow, boosting horsepower, and reducing backpressure. This high-performance upgrade enhances engine efficiency, fuel economy, and throttle response. Ideal for off-road use, it provides a direct-fit solution for the 6.6L Duramax, making installation quick and easy.

Vehicle Compatibility:

2015 is a split year. The 2011-2015 downpipe is secured to the turbo-direct pipe using a V-band style clamp. The 2015.5-2016 uses a 3-bolt flange style connection. Be sure to visually verify the clamp style your truck is equipped with.

Product Features and Benefits

The DynoVox 4-inch Exhaust is made of high quality T-409 stainless steel with a thickness of 2 mm. It is rigorously tested for corrosion resistance and durability to ensure long term stable operation. The aluminized silver finish is not only aesthetically pleasing, but also provides excellent performance.

With this exhaust installed, you can easily remove the diesel particulate filter (DPF) and exhaust gas recirculation (EGR) system, effectively increasing horsepower and significantly improving fuel economy. It restores power to your pickup while reducing fuel costs.

Installation:

Installation typically takes about 1 hour using basic hand tools and can be done on the floor of your driveway or garage. Using a car lift may be faster. For vehicles with shorter wheelbase bed/cab configurations, some cutting may be required. This includes clamps, hangers, and hardware, but you may need to reuse some of the stock parts.

Tuner is required:

Deleting the DPF, CAT, SCR, and/or DOC requires eliminating emissions-related sensors. To avoid triggering a Check Engine Light or Diagnostic Trouble Code, a tuner with DPF Delete capability must be used.
