Flo-Pro 4" Cat Back Dual Kit For 2011-2015 Duramax LML (Aluminized w/o Muffler)

Flo-Pro puts great care into the cat back dual exhausts that they create, and their attention to detail is just as obvious here. Here is a great system for your GM truck's 6.6L Duramax engine, designed to improve exhaust flow on the racetrack. Available now for a 2011, 2012, 2013, 2014, or 2015 Sierra or Silverado 2500 or 3500 with GM Duramax engine. Fits Crew Cab, Extended Cab, and short or long bed trucks. This kit deletes the diesel particulate filter (DPF), the diesel emissions fluid (DEF) system, the diesel oxidation catalyst (DOC) and mufflers so it is not street legal.

Aluminized Steel for Longer Life on Your Silverado or Sierra, Affordable Cost

If you're looking for a cat back diesel exhaust that's one step above the rest, you've come to the right place. Flo-Pro makes this cat back dual kit out of aluminized steel to last longer and be a great value. To keep your cat back lasting longer, Flo-Pro has included 6-7 inches of welding on their hangers and lapjoint stainless steel clamps to prevent any further long-term damage or warping that may be caused by lesser quality hangars and clamps. This kit comes with all the parts you need for an easy installation! Note: you’ll need programming otherwise this cat back will trigger a code and check engine light. Off-road use only.
