I just installed my Akrapovic exhaust at a friends shop this weekend. Those of you who are familiar with the name Akrapovic know that they make some of the finest titanium motorcycle available. When I heard they made a full titanium exhaust for the M3, based on my experience with their product in the motorcycle world, I decided that would be the way to go. Overall, I am very happy with this exhaust. The quality and construction are amazing. The sound is perfect for me, since I didn't want something that was going to be too loud for a daily driven car. We did some before and after dyno runs as well. The dyno is a Dyno Dynamics, so the numbers read a little low compared to others, but the car picked up 16 hp and 21 ft/lb tq at the wheels.

can't see the video (company firewall)... looks sweet though. What's with the inconsistent power between 2500-3500 RPM?

EDIT: how much weight does this save?

 

My understanding is that since it is a load bearing dyno, as it is loading, you see some spikes.

 

Full Ti, right?

VERY nice.

 

the spikes are here when you see the car do little bumps on the dyno.

 

Yes, the exhaust is full Ti.

 

perfect sound. Congrats Ara.

 

sweet ara. i'll have to hear this in person one day.

 

Mark, let's try to do Chiba next Tuesday or Thursday.

 

either day works for me.
