Frequently Asked Questions
Does this bolt up to the factory catalytic converter?
Yes. This catback system connects at the factory converter outlet and mounts at OEM mounting points — no adapter pipes or rerouting needed.
Will I need a tune after installing this?
This exhaust is a passive bolt-on with no electronic components, so no tune is required. Some owners add a tuner separately for added performance, but it's not mandatory for installation.
What's the difference between stainless and aluminized steel?
Stainless won't rust or corrode in any climate — it's built to last the life of the truck. Aluminized systems are cheaper but will eventually pit and fail, especially around moisture and salt. Stainless is the diesel standard.
