BMW M5 Valved Cat-Back Exhaust System

Engineered exclusively for the BMW M5 G90 and G99, this valved cat-back exhaust system enhances the car’s powerful V8 soundtrack while ensuring precise OEM-style fitment. Constructed from high-quality stainless steel with an optional titanium upgrade, it features a quad-exit layout and integrated valvetronic technology, allowing you to tailor the exhaust tone to your preference. Optional tip finishes are available to complete the look.

The system includes complete cat-back piping, premium clamps and fittings, valve actuators (where applicable), and a remote-control module for effortless valve operation. Each exhaust is hand-built to order with precision welding to guarantee durability, performance, and a perfect fit on standard vehicles.

Adjustable valves let you switch from a refined, subdued tone for daily driving to a more aggressive open-valve setting when you want to showcase the M5’s performance character.

Production takes up to four weeks from order confirmation, with next-day dispatch once complete. Returns and refunds are accepted only in cases of verified manufacturing defects.
