BMW M3 / BMW M4 Valved Cat-Back Exhaust System

Specifically engineered for the BMW M3 and M4 E90, E92, and E93 models, this valved cat-back exhaust system delivers an enhanced exhaust note, improved performance, and precision OEM-style fitment. Constructed from premium stainless steel, with an optional titanium upgrade, it features a quad-exit design and integrated valvetronic technology for fully adjustable sound. A range of exhaust tip finishes is available to complement your vehicle’s style.

Each system comes complete with full cat-back piping, high-quality clamps and fittings, valve actuators (where applicable), and a dedicated remote-control module for easy valve operation. Every exhaust is hand-built to order using precision welding to ensure strength, longevity, and a seamless fit on standard vehicles.

The adjustable valve functionality allows you to switch from a controlled, refined tone for everyday driving to a bold open-valve roar when you want maximum presence on the road.

Production typically takes up to four weeks from order confirmation, with next-day dispatch once your system is complete. Returns and refunds are accepted only for confirmed manufacturing defects.
