Special Pricing! Supersprint makes these straight pipes to delete the rear resonator on the MZ4 models. The stock exhaust is over muffled with two sets of cats, the rear resonator, and two rear mufflers. If you want a bit more sound from the S54 to come through this is a great addition. Deleting the resonator will add a bit more volume and makes the system less restrictive for a modest power and torque increase. If you want a more dramatic change to the exhaust, we suggest changing the rear mufflers and possibly deleting the secondary cats. Supersprint mufflers are required for a direct fit.
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!
