Supersprint tubular headers for the F90 M5. This manifold has larger diameter headers that make great power at high RPM. 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 preference. 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!

The factory M5 exhaust system is pretty wide open with minimal restrictions - except for the catalytic converter. The factory cat is the biggest restriction so any exhaust work to gain more power is going to have to involve replacing it with something freer-flowing. Supersprint's downpipe incorporates an ultra high-flow HJS 200-cell metallic cat that flows considerably more than the stock ceramic part. It also uses bigger 80mm piping to minimize restrictions. 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.

Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation! Supersprint metallic sport catalytic converters are sourced from HJS of Germany. For 30 years HJS has been supplying motorsports teams with sport cats when rules required them. HJS is now a worldwide leader in sport cat technology and performance. Rally cars, German DTM, and Formula 3 all rely on HJS for clean, reliable horsepower. Supersprint works closely with HJS to spec a catalytic converter that is correct for the vehicle and engine package. This allows for a substantial increase in flow but which, at the same time, keeps the environmental specs within European limits. With any high-flow catalytic converter, special software or other work may be required to keep emissions fault codes and check engine lights from displaying. Supersprint catalytic converters are sold for track and other off-road uses only. 200-cell cats have 200 honeycomb cells per square inch. This is much better flow than stock but still does a good job of cleansing the exhaust.
