For what I have heard and watched on videos you need to take some sort of tool and grab it and drag real hard while you wiggle it. Which may result in damaging the DB-killer. Only cosmetic damage but still annoying. So try and live with it installed I think you will find the sound without it to much in the long run.Hello!
Anyone have any good tips on how to remove the Akrapovic DB-killer?? I've removed the screw that holds it in place, but it won't budge even when warmed up..
exhaust needs to be cold as metal expands when warm. You have to get some pliers with a rag and pull and twist as best you can. Pretty crap and it will damage the pipes. I used a bit of wd40 sparyed also into edges, If you take it our the DB is way to heavy and loud. Ive put mine back in an dcut the pipes.[video=youtube;R9ydssH5qRk]https://www.youtube.com/watch?v=R9ydssH5qRk[/video]
I actually just keep the screw and the grommet with the db-killer, so I know where it is if I want to put it back.Ok, forgive me for asking such a rudimentary question, but after removing the screw that holds the DB Killer in place, what are you guys doing with it?
It's like a rubber end cap on the outside, with a nut on the inside right? Or is the DB Killer internally threaded so no nut is needed?
Either way, are people putting it back in, or are they just leaving the hole empty?

Ok, perfect. So you just leave the little hole exposed. You think that messes with the sound at all? I was thinking of leaving the rubber grommet in place, but I figured the pressure from the exhaust gasses would pop it out and then if I ever wanted to use the DB Killer I'd have to order a new grommet.I actually just keep the screw and the grommet with the db-killer, so I know where it is if I want to put it back.
The db-killer has a nut welded in place, so it has its own threads. The tailpipe is not threaded, so if you want to put the screw back in, you'd have to insert your own nut, and that just seems like extra work for no reason to me.
Ya, it is LOUD. I've used my bike two times since I installed akra without db killer, and I think I might have lost a bit of hearing. Gonna try out your level of modification.I ended up modifying my dbk and refitting , have the perfect balance now , volume in between dbk in and out

That hole is so small compared to the outlet, it makes zero difference. And its on the inside of the unit, so it wont show either.Ok, perfect. So you just leave the little hole exposed.

Looks like I'll leave the hole exposed then...thanks for the info!

Mellanslag, the note changes slightly , by the number of holes you drill the position of the holes and the diameter of hole you make. My advice start with one small hole? Run the engine test the sound. Then repeat until you have the volume you like... I have to be honest I didn't notice a particular note change just a steady increase in volume with each hole.... You also inherit a nice BBBRRAappp deep rasp , similar to without the dbk but only noticeable 5-6k revs plus. Personally I love it, quiet when I need it to be but a nice growl on demand [emoji106]Ya, it is LOUD.
