Description Fitment FAQ Shipping & Returns

Unlock your 2007-2010 6.6L Cummins's true potential with this high-performance DPF delete pipe. Our precision-engineered solution eliminates restrictive factory filters, dramatically reducing exhaust gas temperatures (EGTs) while improving turbo spool-up and throttle response. The mandrel-bent construction ensures maximum flow efficiency, helping your diesel breathe easier. Perfect for off-road enthusiasts seeking better power delivery and reduced maintenance hassles.

Specification

Exhaust Material T-409 Stainless Steel, it is magnetic.
Thickness 2mm
Inlet Diameter  4.0"/5.0‘’
mandrel-bent construction Maximum flow efficiency, helping your diesel breathe easier

 

Benefits

Expect to see a significant increase in fuel mileage. If your DPF is plugged up your probably averaging about 13-14 mpg. More or less depending on the severity of the restriction. After deleting the DPF/CAT expect to get a combined mileage of 18-19 mpg.

  • It removes the need to service the DPF at regular intervals (cleaning, replacement)
  • A DPF delete will remove the possibility of a DPF failure which could cause expensive diesel repairs
  • Due to less exhaust backpressure, the DPF delete increases exhaust flow and therefore increases the performance of your motor!
  • Paired with an ECU remap, the DPF delete is proven to increase power and torque for all vehicles

Installation

Install takes about 1hr with basic hand tools done on the ground of your driveway or garage. Quicker if you have automotive style lift. Cutting may be be required to fit shorter wheelbase bed/cab configurations. Clamps, hangers and hardware are included. You may have to re-use some factory hardware.
Tuner Required: Removal of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting.

It fits!

Plug and play. Only thing keeping it from 5 stars is why in the heck do y’all not charge a little more and ship with new exhaust flange gaskets??? Had to order them in from local car quest.

Pretty good

For the price it’s unbeatable, hangers were a very small amount off but you know they fit so that’s all you can ask for. No rattling at all and the finish on the metal ain’t bad

Perfect bolt up

Perfect bolt up but it sets too close to the cross member “rubs” and vibrates at startup and sometimes at takeoff

LMM 4” Exhaust

Figment was good, but not great. Difficult to keep from contacting either the driveshaft or the bottom of the bedside just above the discharge while keeping in the hangers. Great value.

Was unaware this would not delete the entire exhaust on the truck. Disappointing that it will only delete the DPF and still have the cat
