▀▄ eas | MY11 M3 - Dinan, Akrapovic, Challenge Race+ X-Pipe [Dyno]

As a continuation from Charles' MY11 M3 build from yesterday (see: http://www.m3post.com/forums/showthr...13#post9665913), the pads were bedded in after the Brembo installation. With some time left over, we quickly strapped the car to our in-house dynojet to see what she's made of:

Engine Mods:
- Akrapovic Slip-On Titanium Exhaust System
- Challenge Race+ Stainless Steel X-Pipe, primary/secondary catalyst & resonator delete
- Dinan Performance Engine Software





Unfortunately, we were unable to get a baseline before the mods were installed.

The end results make for some very impressive power gains on pump fuel (91 octane), with room to spare if more power is desired.

Enjoy!

Baselines are in the ~350hp range for stock, not as varied as the e46M3 was.

Very little, if any. Of course, this is subject to opinion as different people have different tastes.
