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.

What’s the difference between 4" and 5" exhaust systems? 4" – Better for mild/moderate tunes, retains some backpressure for low-end torque. 5" – Best for high-horsepower builds, maximizes flow for reduced EGTs and top-end power. Q2. Will a magnet stick to this pipe? Is it really stainless steel? Yes – This pipe uses T-409 stainless steel, which is still magnetic (unlike T-304). It offers excellent corrosion resistance while being more affordable than T-304. Q3. How thick is the pipe? Will it last? 2mm thick T-409 stainless steel – Durable enough for long-term use without excessive weight. Q4. Will this improve performance? Yes! Benefits include: Lower EGTs (Exhaust Gas Temperatures) Faster turbo spool Better fuel efficiency (with proper tuning) No more DPF clogging issues Q5. Is this street legal? ⚠ Off-Road Use Only – DPF removal is illegal for on-road vehicles in most regions. For competition/racing use only. ---tab Shipping & Returns--- Fast Shipping Policy Your order will be dispatched within 1-2 business days, and the package will arrive within your order's estimated date.
