Bring on the noise! RPi Exhaust is here..

As part of our weight loss program we have gone for a Axle Back RPi exhaust, so the Z4M should sound a lot louder like the animal it is. Plus apparently there will be a few wHp power gain too!

First impressions, its very well made and a quality piece of kit..

For now we have done a static noise test on the OEM exhaust so we can compare once this new one is fitted:

87.5 dBA @ 6000 rpm for the OEM
