This front exhaust section eliminates the factory secondary cats on the N54 cars for better flow and more power. As with any turbo engine, the key to making more power is managing airflow. In the exhaust if you remove restrictions and increase piping diameter the exhaust gasses can flow faster which relieves work for the turbos. This set of Supersprint front pipes elminates the secondary cats located after the downpipes. This turns the N54 exhaust layout into something closer to the N55 engine layout. Combine this with the Supersprint section 2 x-pipe for a full straight through design. This front section also fits N55 cars and has slightly larger mandrel-bent piping.
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!
