This section includes a set of sport catalytic converters to work with the cat-less Supersprint performance headers. This section replaces the front exhaust ahead of the stock center resonator. The sport cats are designed to be a free-flow design for the least restriction but still providing a catalyzing effect to the exhaust. The less restriction is great for making more peak horsepower and torque. You can pair this section 1 with the Supersprint section 2 that deletes the center resonator and you will get more engine volume and a sporty BMW rasp from the M54 inline-6. These cats have O2 bungs on the backside of the cats so you can extend your oxygen sensors to work with these cats. This will give you a near-stock system that's close to a Euro exhaust layout.

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!

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.
