FAQ

Q: What do I need to know before ordering a diesel delete kit?

A: Confirm the model year, engine or Duramax code, pickup versus cab-and-chassis configuration, and current exhaust layout. Then check exactly which EGR, DPF, DEF, CCV, exhaust, and tuner components the selected variant includes.

Q: Does a full diesel delete kit come with a tuner?

A: Not always. Some full diesel delete kits include a tuner and supported tuning workflow, while others contain only mechanical hardware. Check the selected option and cart contents before ordering.

Q: Will a pickup diesel delete kit fit a cab-and-chassis truck?

A: Do not assume it will. Cab-and-chassis trucks can use different exhaust layouts and calibration requirements. Order only when the product page specifically confirms cab-and-chassis fitment.

Q: Should I choose a 4-inch or 5-inch delete exhaust?

A: Choose the size and layout specified for your truck and preferred sound level. A 5-inch system is typically louder, while downpipe-back, turbo-back, and muffler availability depends on the exact application.

Q: Are diesel delete kits legal for street use?

A: These products are intended for off-road, closed-course, and race-use applications where permitted. Emissions regulations vary, so check the laws applying to your vehicle and location before purchase or installation.
