Free ground shipping! Supersprint makes these straight pipes to delete the rear resonator on the Z4 M 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 preference. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation! This item fits the following BMWs: 2006-2008 E85 E86 BMW Z4 M Roadster M Coupe

Supersprint has a wide variety of exhaust components available for the Z4 M Coupe and Roadster. You can pick and choose from either a 60mm Exhaust manifold, designed for increased exhaust flow and higher power potential, or a 63.5mm Racing Exhaust Manifold, built entirely for the best exhaust flow possible! To accompany the headers, you again have the choice of either a catted Section 1 exhaust pipes that feature high-flow metallic catalytic converters, keeping emissions down, or straight Section 1 pipes that eliminate the secondary catalytic converters, eliminating unnecessary exhaust restrictions. Available either as a part of a full system or by itself, the Supersprint Section 2 X-Pipe is the perfect replacement for the factory x-pipe that is resonated and adds another point of excessive restriction and muffling. The Supersprint X-pipe has a straight-through design that provides better flow characteristics and gives your BMW a slightly more aggressive exhaust note. The last set of exhaust components available are the Mufflers and the optional connecting kit. Available in two versions, Sport or Race, Supersprint mufflers are designed with power in mind, while still giving amazing exhaust tones! The Sport mufflers are slightly louder than stock and flow much better than the stock mufflers, and the Race mufflers are even louder and more free-flowing, giving your Z4 M an amazing exhaust sound that never gets old! If you want to run only the mufflers and not any of the other components, you must also purchase the connecting kit which allows you to pair the mufflers with your stock x-pipe. If you decide to go with the Supersprint X-pipe, the connecting kit is not needed. 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.

 The Supersprint 'Race' rear muffler system is one step beyond the standard Sport mufflers. Don't be fooled by the name - the 'Race' mufflers are designed for street use and the name only distinguishes it from the quieter standard Sport system. With the stock system the sound is very subdued. With the 'Race' mufflers the sound is much more noticeable and more aggressive - a perfect sound to compliment the assertive nature of an M Coupe or Roadster. You will hear this exhaust but it will not be intrusive or sound out of place on a civilized sports/GT car like the MZ4. The Supersprint center pipes to delete the rear resonators for more volume can be a welcome addition. 

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.

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!

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. Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation! NOTE: Supersprint engineers and manufactures complete exhaust systems. This part was designed to be used with the rest of the Supersprint system on this car but may be used on its own.

Free ground shipping! Supersprint sport cats for the Z4 M are designed to work with their cat-less headers or to replace factory US cats. The Supersprint sport cats are much freer-flowing than a traditional stock cat. With less restriction, less effort is required to move the exhaust gasses which will free up horsepower and torque. This cat section will mount to the Supersprint headers (p/n 787501) and then to any section 2. This section is built with O2 sensor bungs pre-installed after the cat if you wanted to extend your stock post-cat O2 sensors (however, special software may still be needed). 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. Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!
