Presenting the Dual 4" Cat-Back DPF-Delete Exhaust without Muffler for your 2011 or 2012 Chevy/GMC 6.6L Duramax LML — engineered to look and sound just like the off-road racing monster it’s been dying to be! Designed for closed-course racing, the Dual 4" DPF-Delete Exhaust replaces the Diesel Particulate Filter with dual free flowing 4" aluminized steel mandrel-bent pipes — so no more clogged DPFs to end your day at the track early. It’s time to step up your game and leave the others behind in your Duramax LML exhaust smoke.

Key Features

• Free flowing 4" DUAL mandrel-bent pipes
• Bolt-On Design — No cutting or welding necessary
• Dual outlets
• Replaces exhaust system from catalytic converter to tail pipe
• Removes the DPF – reducing damaging EGT’s and premature engine wear & tear

• Requires a Duramax LML compatible H&S tuner — XRT Pro, Mini Maxx or Black Maxx to work correctly
• The Excellent customer service & support for which H&S Performance is known

^{The H&S Tuners: XRT Pro, Black Maxx & the Mini Maxx}

H&S exhausts are designed for maximum flow with straight-piped sound. You can be sure these dual mandrel-bent pipes flow better than anything else out there, and sound even better! When used with one of the Duramax LML compatible H&S tuners — XRT Pro, Mini Maxx or Black Maxx — the DPF-Delete with 4" duals will not throw error codes or trigger the Check Engine Light. When you’re ready to take your 2011 or 2012 6.6L Duramax LML to new performance heights while making it look good — an off-road exhaust system from H&S Performance is in your future! Not only will you feel the difference on the track, you’ll hear it too! Recently H&S installed the DPF-Delete exhaust kit -– with their Black Maxx tuner set to *"Hot!" Listen to this!

Consider including a stainless steel H&S universal tip to complete this ground-breaking exhaust system. Choose from either a 5" or 6" rolled-edged angled tip or a shorter 13" long 5" outlet, resonated double walled slanted tip for a dramatic looking effect. All tips presented here are bolt on kits for easy & secure installation.

Removal of the DEF/UREA tank standard in all 2011 6.6L Duramax LML’s is recommended but NOT required when running H&S Performance DPF-Removed Tuning.
