From the daddy of DPF Deletes, H&S Performance, comes the 4" Turbo Down Pipe-Back DPF-Delete Exhaust with Muffler for your 2007.5-2010 Chevy/GMC 6.6L Duramax LMM off-road racing monster. Designed for closed-course racing, the 4" DPF-Delete Exhaust replaces the Diesel Particulate Filter with free flowing 4" aluminized steel mandrel-bent piping – so no more clogged DPFs to end your day at the track early!

Key Features

• High-Flow Muffler
• No welding or cutting necessary — all hangers are pre-welded on
• Replaces entire exhaust system from downpipe to tail pipe with 4" free-flowing mandrel-bent pipes.
• 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 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 4" DPF-Delete will not throw error codes or trigger the Check Engine Light. When you’re ready to take your 6.6L Duramax to new heights, go with an off-road exhaust system from H&S Performance! 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 your 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.

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:

• All DPF-Delete kits will engage the Check Engine Light unless they are installed in conjunction with an H&S Tuner.
• There aren’t any threaded bungs welded into this exhaust kit. No Bungs! H&S exhaust kits are designed to work with H&S Tuners which do not require any sensors to be re-installed into the new exhaust system.
• This exhaust kit does NOT include Tip
