Do you guys notice a rare light clanking noise under 2k RPM when the car is trying to speed up form a crawl? Can happen anywhere, but maybe more noticeable when you are climbing?
EDIT: It is most noticeable in higher gears. I am pretty sure this is normal and can be heard in all Akra Evo M3s, but since it's not very noticeable most people probably don't heard it. I think the following thread is talking about the same thing http://www.m3post.com/forums/showthread.php?t=477144&highlight=akra+noise. Put it in higher gears (4, 5, or 6) and give it a bit more gas, you'll probably hear what I am talking about at around 2k RPM. Last edited by eNCore; 04-10-2012 at 09:34 PM.. |

Switch to a higher gear and give it a little more throttle then you'll hear it!

Check that the front section is not making contact with anything - from the secondary o2's to the transmission area. The engine has a resonance around 2k that can cause the front section on any exhaust to vibrate. If it isn't installed properly, there is a chance it could be rattling.
I would not suspect the rear section as it is pretty damn hard to screw up that part of the installation. |

my guess would be a clearance issue as stated above. Heat shield or o2 sensor, etc.
Mine is great no issues.
