Has anyone pulled this off? I have drilled the weld, but the baffle won't come out. I can't disassemble the pipe (to knock it out from the back) because it's welded together. I just can't get it to unstick by pulling on it with pliers. Any advice would be appreciated.

I would also like to know how people have done this. I've seen a video where someone has done it but it was a Dyno test so no info on how it was done.

I've tried to fashion together some clips that I can slide down the center of the exhaust to pull it out from the bottom. However I havent tried this yet so I will let you know how it goes later.

Watching with interest, I've drilled the wels and tried pulling it with bent wire in the baffle holes but no joy...

We are going to have to collectively solve this. It can be done, I feel like I may be missing something as I had no luck last night either. Maybe I can get Yamaha to do it for me whilst they fix the issues with the recall!

I found this article:

Looks like you need to use mole grips and a hammer. Saving the baffle isn't an option.

Just a thought but have any of you tried to remove the baffles with the exhaust hot??.. you never know the expansion of the outer can might make it easier....worth a try.

Success! Vice grips and a hammer while hot.

I've tried this method and managed to get the baffle out by about 1mm but it won't budge any further. @Tom_Aus I have PM'd you for any more advice - it's one stubborn DB Killer but I will get it out!...

I actually thought that was a video of you hammering the baffle out haha!

That does sound incredible!!!!!
I really really want the scorpion serkat exhaust but im feeling to tight to buy 1 at the mo........or any mods to be fair lol

 

[Tom_Aus]

i had the exhaust replaced after a crash. i'll need to do it again when it comes back because the shop won't do it for me. i'll post a video when i take it out again. should be hrs of me cursing for everyone to enjoy

Just got my hands on an 2. hand Acrapovic high mount without the cat, but with db killer. I must say, the sound is now perfekt for my taste. The db killer has a bolt / nut (No welding) so can probably be removed for fun. But I really dont need any louder. I know some dont like the looks of high mount Akra. But man, I think it looks Great!

Hello there !

I've been digging around the internet and I didn't find any precise tutorial on how to get the baffle out.
For the few of you that managed to pull it out (no joke intended), what did you have do ?

OK - Drill the welding point on the can
OK - Hold strong with the mole grips and pull even stronger

Did you strip the whole exhaust system ?
What are we supposed to hit with the hammer ? The can ? The baffle itself (doesn't seem practical at all) ?

 

[AidanAus]

Anyone have any luck with this since? Loving my new high mount Akrapovic, but want that DB killer gone! Preferably salvageable if needed again at a later date..

Coming back from a bike repair shop where two big guys did their best for 45min to get the baffle out : they drilled the welding point, tried an extractor, mole grips + hammer, WD40, all this while the can was hot, but the baffle didn't move AT ALL.

Depressing.
I'm starting to think the baffle welded itself to the can (the bike is 20 000km, the exhaust was mounted at 0km).

If any one of those who got through successfully could make us a step by step tuto, that would be hella helpful !

Refering to an earlier suggestion about getting it hot worked for me. Came out like butter when I got back from a ride and it was in perfect condition....this was lucky because the first time I went out without the baffle, the bike started misfiring and I burnt out the exhaust sensor.

My question being will I need to get this set up on a Dyno if I want to do this again? Because let's face it, I want to do it again.

Hey Jak !

May I ask you to precise what you did exactly ? Just went out for a ride to heat up the exhaust, then simply pulled the baffle while it was hot ?

I may give it another try.

I used a pair of grips and just pulled it out when it was hot. Taking to account you've already drilled out the weld. Managed to do it with very little force which saved me from damaging the DB killer itself.

Alright, I tried again, to no avail.
The exhaust was hotter than our respective moms, I did drill out the weld long ago and way wider than it was made, but spilling WD40 all over the outer ring of the DB killer, using a mole grip and 70% of my overall strength didn't make it move at all.

My exhaust has about 22 000km, is it possible that it welded itself to the can ?

Btw : I did damage the DB killer, it's not that round, now...

Help

Still having trouble getting the db killer out. Have drilled through weld (just one?) and gripping with vice grabs and hitting grips with hammer. Does not budge... any advice?
