From the daddy of DPF Deletes, H&S Performance, comes the Dual 4" Turbo Down Pipe-Back DPF-Delete Exhaust without Muffler to make your 2007.5-2010 Chevy/GMC 6.6L Duramax LMM look and sound just like the off-road racing monster it’s meant 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!

Key Features

• Free flowing 4" DUAL mandrel-bent pipes
• Bolt-On Design — No cutting or welding necessary
• Dual outlets
• Replaces entire exhaust system from downpipe to tail pipe
• Removes the DPF – reducing damaging EGT’s and premature engine wear & tear
• Requires an 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 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 6.6L Duramax 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 two stainless steel H&S universal tips to complete this exciting exhaust system. Choose from either 5" or 6" rolled-edged angled tips or shorter 13" long 5" outlet, resonated double walled slanted tips for a dramatic looking effect. All tips presented here are bolt on kits for easy & secure installation.

This is a Race Only product used solely for competition. Its use is limited to closed-course racing that is formally sanctioned by a recognized racing organization. Any other use, including recreational off-road use, could be in violation of local, state and federal laws.

Notes:
