💬 What Customers Say

"Insane sound. Perfect fitment and fast shipping. Car feels way more alive now. Will be back for the tune!"

– @c43marco

"Didn’t think I’d notice this big of a difference. Turbo spools way quicker, and the coating really helped with underhood temps."

– Chris A., E43 Owner

❓ Frequently Asked Questions

  • Will this trigger a check engine light?
    Yes. Removing factory catalytic converters will trigger a CEL unless the ECU is tuned. We offer discounted tuning with purchase.
  • Do I need an ECU tune?
    Yes. Tuning is required for CEL removal and to realize the full performance potential of these downpipes.
  • Is ceramic coating worth it?
    Absolutely — it lowers engine bay temps, improves flow, and extends component life, especially under repeated full-throttle use.
  • Is this legal?
    No. These downpipes are for off-road or competition use only. Always check your local emissions laws.
