Our customer has managed to record the highest trap speed thus far with the M3/M4 platform. Known as NJ_M4 to the forums, Dave has come back in pursuit of shaving some more time off his seasons best, 10.36 at 136 is not enough!

Running 10.3 at 136 mph was very impressive, but what was possibly even more impressive was the minimal amount of modifications required. Like most who modify their personal cars, the process becomes both rewarding and addictive, and as the horsepower and capability of the car grows, so do the customer expectations. In attempt to inch closer to that elusive 9 second mark the car is back today to shed some weight.

To improve the exhaust and increase performance we have elected to install an Akrapovic catback System on this car. Previously a resonator delete was performed at another facility and the result was a car that was louder, but didn’t necessarily sound “better”. When making improvements to well-designed vehicles, improving slightly beyond stock is easy, but to reach the highest levels of performance and reliability the best parts must be sought out. Luckily the professionals at Akrapovic not only can create and design exhaust systems with the utmost regard to performance, but they also have the technology to engineer the exhaust note.
