E60 M5, E63 M6 Supersprint Cat-Delete Downpipes (Deletes Primary Cats In Manifold)

Free ground shipping! One key to making power from the S85 V10 is eliminating the factory catalytic converters in the manifold. Ideally, the best way to do this is with a set of Supersprint tubular headers. But if you want to keep your stock manifold and 'gut' the stock cats from them these pipes are the way to go. The stock cats are cut along an existing weld in each manifold and this piece is welded in place. Special software or modules will be required to keep fault codes and check engine lights from coming on. O2 sensor and EGT sensor bungs are pre-installed. Any Supersprint section 1 piece will bolt on to these downpipes.

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!
