My M4: Akrapovic Evolution Exhaust (Pics + Vids)

JustinCredibleM · 12-03-2014, 02:01 PM

First off -- I want to give a HUGE shoutout and thank you to European Auto Source for getting this done for me. They spent the whole day meticulously working on my car to install a bunch of delicious goodies on my car. Here are some awesome pictures of the exhaust (it's a god damn piece of art) and install.

VIDEOS!!!

Thanks again to eAs for doing such a great job on my car

What's going on at 1:26 and 1:39 on the Dyno? Sound almost doubles in volume it seems like.

Nice sound! I think DP's are a must to get a good tone from any exhaust setup. The ER akra combo is pretty nice.

The sounds is from the exhaust valves are opening up mid-run.

JustinCredibleM: Glad you are happy with your new baby, thanks for allow us to be part of your build!

That's what I was thinking but I was unsure how they operate.

I very much like when they open... Lol

Thank you for the info!

this is awesome! congrats

To me, these are the best looking exhausts. Not sure if the sound is better than other after markets. Sounds good though.

I would go for their diffuser as well, pricey but gorgeous.

I think the flaps open up in the exhaust so it gets louder

I just installed the Akra Evo and ER DPs and it feels like the car is making less power?? Haven't dynoed but just feels sluggish and f'ing noisy

Waiting for my ESS software piggy back hope that will make me smile
