Dyno Results

Being a prime opportunity for dyno data, we were able to get a baseline and after result with the system installed. With a peak gain of 7whp on 91 octane, this can mean a couple of things: 1) The BMW factory exhaust is very efficient, or 2) The choke point (likely) is further up at the downpipes.

CONDITIONS


We will be installing Downpipes and the Akrapovic Evolution on our shop M4 to compare results soon.











Completed Installation

Installation is about an hour on the exhaust, the diffuser is literally minutes to install. Once completed, we are greeted with a very aggressive appearance and exhaust note. A set of 15mm/12mm Macht Schnell spacers were also installed to match the stance with the exhaust.

























Hope you enjoyed the experience as much as we did. We'll be installing system #2 shortly on our Austin Yellow M4 w/ Downpipes and following up with comparative results.
