FAQ

Q：How do I choose the right DPF Delete Pipe?

A：Choose based on your sound preference and performance requirements. 4" systems are ideal for daily driving with a balanced tone, while 5" systems maximize airflow and provide a more aggressive exhaust note. Muffler versions help reduce drone, while race versions are louder and more aggressive.

Q：What is the difference between Single Tune and SOTF Tune?

A：Single Tune offers one fixed performance calibration. SOTF (Switch-On-The-Fly) lets you switch between multiple performance levels while driving, offering greater flexibility and control.

Q：How long does shipping take for the EZ Lynk tuner?

A：The tuner typically arrives within 5–10 business days and may ship separately from other items.

Q：Is this kit street legal?

A：No. This product is intended for off-road, race, or competition use only, where emissions equipment removal is allowed. Please ensure you check your local regulations before purchasing.

Q：Is professional installation recommended?

A：Yes. Professional installation is highly recommended to ensure proper fitment, correct tuning, and safe operation.
