Akra valves

[Rickzg]

Hi guys, i recently picked up my m5 and it has an akra evolution exhaust on it. It has been on the car for some time now but I really feel the exhaust note is really tame until you really give the car some beans.

I noticed the exhaust does have valves, is it possible to do the exhaust flapper mod on this exhaust or would it cause problems? Getting DP's is out of the question as the car is still under warranty.

Anyone done this before on the Akra??

I don't think you need a MOD just need hose clips, I clipped the valves on my stock exhaust open with garden hose clips from B&Q there is a thread on here how to do it

I haven't had the testicular fortitude to attempt this on my AKRA but should be possible

I wired mine (M performance Akra) open with high temp zip ties

Was there a massive difference in sound? During regular driving
