CB650F How to remove baffle/db-killer Akrapovic?

[Jorgenape]

Hi Guys! I just finished fitting a full Acrapovic exhaust (https://www.akrapovic.com/en/moto/p...egmentId=1&brandId=30&modelId=735&yearId=4861)

to my CB650FA 2018!

Now I'm really wondering if any of you know how to remove the baffle/db-killer on this exhaust?

Thanks!

Bump, No one knows how to remove this?

Call the company and ask. I'm sure they'll tell you any proper way of doing so. If not, get your drill out!!!

Thanks for the reply! I'll try to contact them and see if they have any answers for me

Start there first. I imagine they're going to tell you the baffles should stay. If so, I'm willing to bet most that go this route will have drilled them out. But I could be wrong!

Yeah, I find alot of videos for removing the db-killer from acrapovics other exhaust models for this bike (ie: ) But none for my specific exhaust
Hope the manufacturer has some good answers for me haha

Have you tried that method in the video? Another look at your model and it appears to be more angled. Are those rivets or screws around the muffler?

I Have not tried what they do in the video as I have found no hidden screws anywhere that could be holding onto the baffle.. and those are rivets. Only screws on the muffler are the screws holding the carbon heat shield. Also I tried removing the carbon heat shield to find any hidden screws for the baffle, but there were none

Unless someone else on the forum knows of a trick I'm...baffled! Not sure if the baffles are curved and, if so, I think they're there to stay. Unless the company says different you may be stuck with what you have. Then again, there's always a way to modify anything albeit not an easy job.
Good luck with whatever it is you do!

Yeah, thanks! I might just leave it be, since I guess it will be hard to put back in again if I actually remove it.

DB killer removal

 

[Dottyzebra]

Hi jorgen i have the exact same exhaust on my bike! To remove the db killer take of the end can and then remove the carben fibre piece there will be a slight imperfection somewhere on end piece of exhaust and also on the inside opposite! you can see when looking inside a spot weld. You need to drill out the spot weld using a 10 mm drill bit then spray some Wd40 around edge of db killer and lastly knock out db killer from inside using a long wooden pole or something similar while a friend holds on to exhaust

^^^ This!
Thank you D @Dottyzebra! I also have this exact exhaust and this helped a ton. It's just as you said on the spot weld. The toughest part was the wooden pole thing. It nudged the db killer out about a centimeter as I bashed it in there, but then it got stuck inside. I broke the pole off where it entered the exhaust trying to pull it back out lol. Ended up having to pull the baffle from the front with vice grips wrapped in a rubber glove. After that the remaining stuck piece of wood fell out. So... I'd recommend for some, try to loosen the baffle with a pole, then pull it out from front rather than beating the pole into oblivion. I'd have never gotten through this without this post man. Props!

took me three attacks to get it done. Listen carefully!
- Buy Titanium drill bits (Gold) - All 2017+ Akras are spot welded
- Remove the exhaust can
- wear safety glasses
- Hold it between your legs on a soft and grippy surface (Yoga Matt)
- Pick a bit one size smaller than the bolt and drill few mm to make space for the bigger drill - In your case, there is a mark (a sanded off weld mark) underneath the carbon cover. you have to drill the shield to access the bolt (10mm drill). Same procedure from here.
- Drill the bolt out counter clockwise - it will fall out from the other side.
- Fun part begins! taking the shit out!
- Have a hammer and a metal straw ready
- spray some WD-40 around it and wait for 3 minutes
- insert the pole/straw 45 degrees into the hole you have made and start tapping gently. it will loosen the muffler.
- Get a Tongue pliers and a pair of dish washing gloves (for traction!)
- wrap it around the pliers and bite the db killer
- pull it out like you are extracting a tooth! turn and twist but gently- you may damage the muffler tip.it's buttery soft
- take it out - clean every thing up - put the can back - yell out loud and jump!
- Have a beer and turn it on....
- Congrats!

Congratulations, you now have an obnoxiously loud motorcycle!

JK, if you like it, go for it. However, I do understand why people that live on roads that are popular with bikers get super annoyed but these loud pipes.

Nothing like the sound of a 4 cylinder Honda paired with a proper full system. Maybe not everyone knows that the Akra with the Db-killer in is same sound level as stock. When I brought my bike in to my local Honda dealership for routine maintenance they were excited about my exhaust. Upon returning the bike to me they said "We fired it up in the shop, of course. You'll be wanting to remove that baffle. It's pretty underwhelming." If your dealer is telling you that... well that says something. Not to mention, with a power commander there are substantial performance gains to be had.

That’s not true, it’s definitely louder than stock with the baffle in. Perfect some may say.

will this work with the new model ? I am a noob and there is no video for this model S-H6R14-HEGEHT

same concept. the only deference is that you have to drill the welding mark on the body (under the carbon cap) to attack the bolt
