The Supersprint rear mufflers for the turbo Z4 is a subtle sound and performance improvement for those that think the stock muffler is too tame. This sport rear muffler is a free-flowing design with larger piping to improve flow and tune the sound. With the stock cats in place the sound is still subdued but the Supersprint muffler makes an alteration to the exhaust note to be a little more sporty and aggressive but not intrusive or obnoxious. This system includes the center X-pipe with slightly oversized piping for improved flow over the stock system. This system uses two exhaust tips per side, giving more muscle and presence like BMW uses on their "M" models.

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!

Looking to elevate the acoustics of your X3 M40i / X4 M40i with an exhaust system that not only offers a much-improved sound while retaining the flexibility associated with valves, but also raises the eye appeal beyond the mundane? Look no further than the Dinan valved cat-back to meet all your needs… and then some! 

The full cat-back requires no cutting and utilizes factory mounting locations that allow the Dinan exhaust system to be a straightforward and painless install. Fabricated from brushed 100% T304 stainless steel, TIG welded, and free of hydroformed pipe, the upgraded system is also a marked improvement from its predecessor - both in terms of material/construction as well as in overall looks. The most glaring change being the replacement of the OEM dual slip tips in favor of an M-inspired quad tip configuration. Despite the limited room, Dinan was determined to offer four individually functioning pathways/tips and not lessen the representation with Y-tips or other gimmickry.  The result is a proper quad setup furnished with cavity covering 3.75-inch (95mm) tips in either black ceramic or polished stainless ensuring the system can be appreciated even before it is heard.

While looks are important, the auditory advantages are what any enthusiast is truly after with an exhaust system, and the Dinan offering for the G01/G02 M40i platform delivers in spades. For not only aural enhancement via the elimination of the central collector/resonator, but also weight savings and simplicity. The stock single-to-dual pipe setup has been abandoned in favor of an enlarged, straight, unrestricted, and freer-flowing single pipe system. This pathway feeds into a Helmholtz-equipped muffler that limits frequencies associated with drone, as well as assists in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows versatility in volume levels with the retained factory valve functionality. Go from refined when cruising (low RPM’s) to rowdy when in it (high RPM’s), with ease. Or better yet, pair the system with an exhaust valve remote and have full control of elevating or reducing the sound! When open, the system behaves as a straight pipe solution that promotes maximum flow and volume for an exhilarating and forceful chorus. When the valve is closed, however, exhaust gases are wholly redirected through the muffler and emit more tempered vocals acceptable for even the most sensitive ears. It is the perfect blend of civility when cruising or the full spectrum of auditory delight when in the throttle. No matter the situation, the Dinan valved cat-back exhaust system is the answer for the discerning enthusiast looking for sound without sacrifice.
