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

Flo-Pro puts great care into their cat back dual exhausts and their attention to detail is just as obvious here. This is a great system for your GM truck's 6.6L Duramax engine, designed to improve exhaust flow on the racetrack. This system comes with a machined flange to perfectly match your stock or aftermarket turbo. 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 diesel 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.

Stainless Steel for Longer Life on your Silverado or Sierra

If you're looking for a cat back diesel exhaust that won’t rust out, you've come to the right place. Flo-Pro makes this cat back dual kit from stainless steel. To keep your cat back lasting longer, Flo-Pro has included 6-7 inches of welding on their hangers for long life, and lapjoint stainless steel clamps to prevent any warping to the tubing. This kit comes with all the parts you need for an easy installation! Note: you’ll need programming otherwise this cat back will trigger an engine code and the check engine light. Off-road use only.
