FAQ
Q1: Do I need a tuner?
A1: Yes. It’s required to prevent check engine lights and ensure smooth operation.
Q2: Will this fit Cab & Chassis models?
A2: No. These models require a longer pipe. Contact us for assistance.
Q3: Is it legal to use on public roads?
A3: No. DPF delete kits are intended for off-road or racing use only.
Q4: What’s the difference between DPF and DEF delete?
A4: DPF targets the filter; DEF targets the fluid system. This kit only removes the filter.
Q5: Is this kit complete, or do I need extra parts?
A5: This kit includes everything you need for installation, including the pipes, clamps, and hardware.
Q6: How do I know which connection my 2015 Duramax has?
A6: 2015 is a split year. Early 2015 models use a V-band clamp connection, while late 2015 (2015.5) models use a 3-bolt flange. Please visually check your factory downpipe connection before ordering.
Q7: How much will my fuel economy improve after the delete?
A7: By reducing exhaust backpressure and eliminating forced regeneration cycles, you can see a fuel economy boost of up to 25%, depending on your driving habits and tuning.
Q8: What material is the delete pipe made of?
A8: This DPF delete kit is constructed from T409 stainless steel, which offers excellent corrosion resistance and durability for heavy-duty use.
Q9: How long does it take to install this kit?
A9: The installation is a direct bolt-on process that typically takes around 1.5 to 2 hours using basic hand tools. A lift is optional but recommended for easier access.
Q10: Will this DPF delete kit make my Duramax louder?
A10: Yes, removing the restrictive factory DPF will give your 6.6L LML Duramax a deeper, more aggressive exhaust tone and make the turbo whistle more noticeable.
