Removing DB-killer Akrapovic 2017 Euro4
« on: July 02, 2017, 04:09:29 PM »
Today I removed the db-killer from my Akrapovic 2017 Euro 4. Just drill a 2mm hole in the carbon, if you look inside you can see where the bolt sits. Go up in size till you hit 10mm.
Remove the hex bolt, the bolt is welded "tacked?" but it will easily break off, pull out the db-killer. Buy some kind of plug and cover the hole. Literally took me 7 minutes.
Make sure you mask the carbon with covering tape of some kind before drilling.

Did it make a significant difference in the sound?

Not really but I have racing headers, more darker sound and a bit louder.
More significant difference in the sound if you still uses the original headers I guess.

Thanks for the info!

Did you change the tune after installing the full Akrapovič system?

No, but I will next week. Tune or no tune, full system did a big difference straight away.

How did you know you have to dril this place? I mean, if I check exhaust from the end of, there are 3 places which looks like they indicates the screw position.

If you look very closely you can see what position of the 3 has the screw. It's on the side towards the wheel. In the same place as on a non-euro4 akrapovic.
My hole is not in the center of the bold. You could drill it about 5 mm more up (if you look at it mounted), Use my picture as reference, look at the rivet and the text.

 You're a legend!  :020:Cant thank you enough for this. I have the same setup.Followed your instructions and it all went according to plan :046:
I was a little nervous drilling a hole into my brand new pipe. Once done I was so happy to be rid of the baffle.Bike feels crisper and sounds deeper and lil louder.
