Full Akra DB killer removal

Post by dukebadboy » Mon Oct 24, 2016 12:07 am

I have 2016 Full Akra and would like to get DB killer out. Turns out it's a quite complicated task.

I figured out that DB killer is being held by some sort of anti-tamper screw. It looks like it consists of 2 parts, one is the actual screw thay you can unscrew and two - some sort of pin that sits below the screw and there is no way to take it out.


Does anyone have any guidance how this can be done? Is drilling the pin out is the only option? Do I need to get titanium drills?

I don't know what you're talking about? On my full akra, you just have to take out the bolt under the rubber plug. Easy as pie. Maybe they changed the design since I bought mine 6 months ago?

Think they have tightened the tolerances a bit on these chaps :o

Had a full system a year ago on my bike and it just came out with the pliers after removing the retaining screw

These new ones are a different ball game

Had a new full system fitted to my new SE and the thing won't budge, managed to get it out in the end with a slide hammer from the inside but took a hell of a lot of force and effort to even start to get it to move

The baffle is useless now as it does damage it so be warned

There has been a lot of talk across the forums that maybe its tac welded somewhere but as far as i can see there are no tac marks on it now its removed - Just a really really tight fit


GOOD LUCK! :mrgreen:

The following letter appears in today's MCN:

Q: Is Euro4 the end of exhaust mods?

A: Euro4 affects all new models introduced in 2016, and all new bikes from 2017. It is focused on hydrocarbon emissions, noise levels, anti-lock brakes and on-board diagnostics.
For an aftermarket exhaust to be Euro4 compliant, it must have passed the relevant homologation testing and be e-marked. Like Euro3, the e-marking will only be valid when used with similarly homologated parts. So it won't be 100% legal combined with a decat link pipe. But of course the visible marking on the muffler remains in place and as there is no toxic emissions test as part of the MOT test in the UK it is difficult to ascertain if a converter is in place.
Under Euro4, physical so-called "defeat" devices, such as bolt-in "removable" baffles and noise-deadening flap valves in the exhaust are no longer permitted. A compliant baffle must be fitted in such a way that its removal will cause permanent, irreversible damage to the exhaust. This sounds a little extreme, but it may just be a case of needing to drill out a pin or rivet, or grind off a weld in order to remove a baffle. The onus is on the manufacturer not to make the exhaust deliberately designed to defeat Euro4 compliance.



Of course, Euro4, like most EU regulations apply at the point of manufacture so bikes and bike parts made within the EU must be Euro4 compliant even if they are for export outside the bloc.
The last paragraph in the reply above would suggest that here in the UK, until we finally leave the EU at least, exhaust cans must be e-marked to pass an MOT. How that will affect our domestic small volume and custom aftermarket exhaust manufacturers I don't know. The sooner we're out of this shit the better. There are Euro5 and Euro6 regulations planned.
Of course big manufacturers love this kind of bureaucratic regulation because compliance is expensive at both design and manufacturing stages which makes it harder for smaller companies to compete, so gradually the corporate big boys establish a monopoly. No surprise then that big name automotive manufacturers are powerful lobbyists within the EU and they always seem by strange coincidence to be years ahead of regulation with their (fully homologated) accessories catalogues.

That's a super informative piece!!!

Unfortunately I'm one of the "luckiest" guys who got end of 2016 exhaust.

Just an update:


I managed to remove the baffle, but this was a very painful process that required:

1. Un-rivet the back carbon piece part and take out the back assembly.

2. Drill the anti-tamper screw out.

3. Using a press machine to push out the baffle

Unfortunately there are two side effects after this:

a. You end up with the whole on the side
b. The outer casing where the baffle sits bends under pressure and it's quite difficult to level it to the original


So the theory about Euro4 standard was the right one. The baffle was fit using an interference fit. The anti tamper screw is just a sham to distract people or a rudiment from the original design.


I will post some photos later on.

hello!

i removed mine without unrivetting anything... but! it was no easy task. Had to hammer it with a big piece of metal that was closest to the baffle size in diameter. After the job done the db killer was in a pretty bad shape and no longer useable. Need to be careful and avoid any dammage inside the silencer. Wondering why some people got this done easy with pliers. Mine is a 2016 also and forgot to mention the side screw was also removed before this process haha :D

Hi guys, mine came out really easily, screw wasn't even that tight, bit of round wood against the baffle, fairly light tap, out came the baffle, very easy. Mine by the way is brand new, bought end of Jan this year, not even on the bike yet.

Maybe it's easier when it's new. I started the removal process after 1k km on it.

Dealer tried to remove mine when new and couldn't. They got it out at first service and gave me a new baffle but I'm relunctant to put it back for track days. On this new baffle it's a bolt not a screw.

After all the trouble getting it out, I'm a bit weary of putting the new one back in for track days.

Anyone have a link to a replacement? I may need it for sound requirements for a trackday
