Akrapovic Exhaust Rattle

MGF82 · 08-18-2018, 09:38 AM

I recently purchased a 2015 M4 with 8K miles. The previous owner had installed a full Akrapovic exhaust system. On cold starts the exhaust makes a horrible rattle noise. I have confirmed it's the exhaust valve. It's also my understanding that this is a know issue with this system.

Can anyone point me in a direction to get this fixed or replaced?

Contact akrapovic directly they will help you out.

Yes, same thing happened with Eisenmann. Unlike other brands, Eisenmann sent us a brand new rear exhaust and reimbursed cost of installation. The old one was returned to IND their main distributor.

Pretty sure Akrapovic will do the same.

Sidebar but had the same issue with factory valve rattle noise in my 997gt3. Just another thing to break.

It's rare that Akra valves rattle, I hear it a lot more when it comes to Eisenmann but never Akrapovic. I know Eisenmann pretty much replaces it if it happens to theirs, I'm certain Akrapovic will do the same if you just take it into a shop that sells their things and they can get the replacement done.
