The F90 M5 continues the powerful legacy of the S63 4.4L twin-turbo engine, yet the factory exhaust system often keeps its true acoustic potential far too quiet. The Valvetronic Designs Valved Titanium Cat-Back system finally unlocks the aggressive soundtrack this car deserves, providing a refined tone for daily driving and a ferocious roar when you decide to push the limits. Crafted entirely from premium Grade 5 titanium with 3.0" tubing from the inlet to the outlet, this lightweight masterpiece integrates seamlessly with your factory controls or operates via a standalone remote for absolute command over your driving experience. Engineered for maximum performance, the forward-mounted, large cross-section X-Pipe significantly improves exhaust scavenging and smooths the overall tone, virtually eliminating unwanted rasp, which is particularly beneficial for vehicles equipped with aftermarket downpipes. This free-flow architecture reduces back pressure to deliver sharper throttle response and a much cleaner note at the top of the rev range. For effortless versatility, the integrated valve control ties directly into the car’s ECU through the Sport and Sport+ settings, while the included standalone remote ensures you can instantly toggle between a stealthy profile and an unrestricted scream in any drive mode.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!
