THIS PRODUCT IS FOR RACE/OFF-ROAD APPLICATIONS ONLY

Vehicle fitment - 2015.5 & 2016 Chevy / GMC Duramax Diesel LML. Silverado and Sierra pickup trucks. Crew cab short bed & crew cab long bed. This will not fit the 3500/4500/5500 Cab & Chassis commercial-style truck.

2015 or 2015.5? - 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.

Exhaust Material - Available in aluminized steel or T-409 stainless steel. Aluminized steel is our most popular but will eventually accumulate surface rust. T-409 stainless steel. Unlike T-304 Stainless its still magnetic. So if your testing to see if you actually got stainless; beware that a magnet will still stick to it. We suggest the stainless upgrade if you regularly operate your truck on salted winter roads. Use the drop-down menu to make the desired selection.

Installation - Install takes approx. 1hr with basic hand tools done on the ground of your driveway or garage. Quicker if you have an automotive-style lift. Cutting might be required to fit shorter wheelbase bed/cab configurations. Clamps, Hangers and hardware are included. You may have to re-use some factory hardware.

Tuner Required - Removal of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting. If you don’t already have a DPF delete capable tuner we recommend the EZ Lynk.

Shipping - In most cases, we have this exhaust in stock. Worst-case scenario the exhaust ships directly from the manufacture. Could take up to 10 business days to build, plus ship time. We try to keep plenty of inventory on hand but in some instances, we have to ship directly from the manufacture. Once your order has been submitted it cannot be canceled.
