Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

NOT ROAD LEGAL - FOR OFF-ROAD AND TRACK USE ONLY

Unlock serious performance from your BMW E90, E92, E93 M3 with the Evolve Primary Cat Delete/Test Pipes. The factory primary catalytic converters are a major restriction on the E9X M3 exhaust system. Replacing them with these Evolve cat delete pipes frees up power, sharpens response and is the most cost effective way to release performance without committing to a full X pipe replacement.

Designed specifically for the OEM X pipe, these Evolve test pipes use a proven slip-on and clamp solution for a tight, secure fit. No welding required. Supplied with 2 new gaskets for a clean install.

  • Direct fit for BMW M3 E90 saloon, E92 coupé, E93 convertible
  • Replaces restrictive primary catalytic converters in the factory X pipe
  • Slip-on and clamp design for a solid, leak-free fit - no welding
  • Dyno proven gains of up to 20 bhp and 20 lb ft torque
  • ECU remap required to remove CEL check engine light and to maximise gains
  • Includes 2x new gaskets
  • Track only - not road legal

If you want the performance benefits without changing the entire mid section, Evolve Primary Cat Delete/Test Pipes are the smart choice. Keep your OEM X pipe, remove the biggest restriction and enjoy noticeable power gains. We run these on our own E9X M3 builds and customer feedback has been consistently excellent.

Why choose these Evolve cat delete/test pipes

  • Best value performance upgrade for the E9X M3 exhaust
  • Clamps and slip joints ensure a precise, serviceable install
  • Perfect for stage 2 tuning when paired with an ECU remap

Fitting and support

Important notes

  • Not road legal. For off-road and motorsport use only.
