What is the DPF and is it worth doing a DPF Delete?

Most post-2007 diesel vehicles are fitted with a Diesel Particulate Filter (DPF) for emissions reasons, however there are a few disadvantages to this device; including constant maintenance and repairs.

Because the DPF clogs up, it increases backpressure. Due to this pressure, the fuel flow is hugely disturbed and slowed down. Therefore, when you remove this filter, the fuel flows much easily and faster, increasing the overall fuel mileage.

Specification

Exhaust Material T-409 Stainless Steel, it is magnetic.
Thickness 2mm
Inlet Diameter  4.0"/5.0‘’

 

Installation

2011-2015 LML 6.6L 4'' DPF Race Intallation Instruction

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.

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

Great fit Great price

Exhaust pipe seems to be good quality. Everything lined up and fits great. The exhaust tip is ok. Not enough room to get a socket on it so had to use the open end of a wrench and even then can only get a 1/4-1/2 turn which took a little bit to get the tip secured. Otherwise happy with my purchase.

The exhaust pieces all went together as they should and fit well. I'm pretty happy with how it turned out. I had to tweak the exhaust hanger that is at the trans cross member some to make it line up but overall will buy in the future

Amazing fit

This kit came exactly as described and fit perfectly it was way easier to install than taking the factory exhaust out and all the hangers are in perfect placement to use the stock hangers over again

Thanks for the review and I look forward to receiving pictures of your installation feedback!
