Is my M Akra Exhaust Defected

I have the M Performance Titanium Akra Exhaust on my 2018 M6 GC Compitition.

Coming from an M4 with M Performance Titanium Exhaust, it had a satisfying sound and enjoybale pops/crackles on downshifting.

My current M6 M Titanuim exhaust I can barely hear it if the windows are up. I hear more of the engine sound. When the windows are down I can hear the rumpling but nothing more. Also, no pops on downshifting.

Overall, I hearing the engine more than exhaust .

Is the exhaust system defect? its still underwarranty with 16k Miles on.

If this is how M Exhaust sound, what can I do to enhance the sound without voiding the warranty ?

How can I get the pops/crackle sound upon shifting up and down??



Your feedback is highly apperciated.

It's subjective, but I assure you the MPE sounds way better than the MPE on a M4.

A few considerations, are you sure you have a MPE? Can you take a picture of the exhaust canister? Sounds crazy, but some people are confused about what comes on a competition package car. The MPE is not standard on a competition car.

Here is a picture:

Also, your car may have ASD unplugged or coded out. And your M4 may have had ASD on. At least check this as well. I remember when I unplugged my ASD, The immediate reaction was the car's interior cabin was quieter and less boomy.

However I could hear my exhaust pop. It only happens in certain situations, hard to duplicate all the time. I can tell you, I definitely can hear my exhaust. Windows down it just sounds amazing.

I went under to ensure I have the right exhaust, based on the pictures, I believe I have the right M exhaust.

I had the flaps coded to be open at all time when I first purchased the M6. Not sure if this ASD was disabled.

would you recommend getting checked at the dealer ? any upgraded would you recommend to get a better aggressive exhaust? [IMG]undefined[/IMG]

Well, you could cut the mufflers off and do a decent muffler delete... And then let me buy the akra mufflers from you.
