❓ Frequently Asked Questions
Will these downpipes work on the stock tune?
Yes, they’ll operate with a stock ECU, but tuning unlocks the full +100 HP potential and prevents CEL light.
Will installing these trigger a check engine light?
Catless downpipes may trigger a CEL. Use O₂ spacers or ECU tuning to resolve.
