Supersprint recently finished research and development on the E89 Z4 platform with the new 4 cylinder 2.0 Turbo N20 and the 6 cylinder 3.0 Turbo. As with all Supersprint exhaust systems, the development was focused on bringing out the most performance from the Z4 while aiming at a sporty and throaty sound.
For pricing information, send us a PM or contact your local Supersprint dealer.
The Z4 28i marks the introduction of the 4 cylinder 2.0 Turbo on the E89 platform. Unfortunately, the OEM sound and aesthetics are a major let down. We set out to develop a full exhaust system with a single and dual rear muffler configuration.
The system uses oversized 70mm piping for improved performance and throttle response. It is available in catted or catless, and resonated or non-resonated configuration.
The tips are available in chromed, black chromed, satin black, satin silver and raw polished stainless steel.
The stock exhaust has various compromises to meet emissions, sound and fitment restrictions. It has various crumpled zones and excessively restrictive 400 cell ceramic cats.
