i removed it, its really nothing, it just allows a smooth transition from the packing to the exit of the muffler.
I just finished putting mine on nod taking Akaoni for a spin.

AWESOME!!!!!!!!!!!!!!!!!!! Is all I can say

nevermind, you can remove a piece out of the muffler. remove the allen screw from the end of the muffler, have to remove the little rubber plug on the carbon tip to get to the nut. The inner sleeve comes out from the inlet side. Then take a bearing puller and remover the little aluminum restrictor.

Got a picture of what your talking about removing? I took out the screw on mine, but can't seem to take out the darker annodized section out. I'm not using a puller though. I will, but am not sure exactly what I'm suppose to be taking out.
got my exhaust today and removed the baffle right away sound amazing and throaty like a pitster pro i just too the rubber piece off the bottom of the exhaust and loosened the 8mm nut and held the top side with an allen then removed the allen and used the spring puller that comes with the exhaust to pull the baffle out
Mine's is really in there. I guess some parts are machined tighter than others. I bent that spring hook, and tried to make something along the lines of a dent puller. It didn't budge. Show me what the parts are that came off. I can figure out the rest. Was it the stainless 1" pipe and the larger 3.5" annodized bezel/ring thing-a-ma-jing?

yes the stainless pipe comes out, but you have to get it out from the inlet side of the muffler. And then use a puller of some type, i used a habor freight bearing puller, to get the 3.5" anodized bezel/ring thing out
So today I removed the screw from the baffle and attempted to pull it out. Whilst trying to pulling it out It looked the metal pipe slid back into the can (F*&!) Does any one mind showing me a picture of their baffle? I would really help to see what I'm trying to take out.

Right now I need to figure out how the hell I'm getting it out......

Here ya go. The grey ring on the shiny pipe comes off (I run mine with the grey ring still installed, but without the sleeve).

Try grabbing it with 2 small allens and walk them around...its a very snug fit, so if you don't pull it evenly out it will hang up...FYI

my new Grom has an rs9 and I tried to remove the baffle today

i found that only the shiney pipe came out via the inlet but the grey ring stayed put, which is fine as it's plenty load like this.

so with the shiney pipe out and grey ring in place do I still need to use the screw to secure the grey ring ?

and if I want to install the shiney pipe again how do i install it ? Pop it in through the inlet or can I push it down via the outlet ?

Sorry for the the questions but the bike didn't come with the manual for the yoshimura rs9 and Google doesn't show much about this.

thanks.

First, this is a really old post, so don't expect a reply from people you quoted.

Second, I love Yoshi pipes, definitely my favorite pipe.

Third, hahaha, getting the baffle out of any Yoshi pipe is a biatch! Slide hammer is the easiest best way. Took me a few bikes and Yoshi systems to learn that. Slide hammers are cheap, $20 from Amazon of Harbor Freight, etc. I don't have the Yoshi on my Grom, but they're all pretty similar. Keep that screw, get a slide hammer, and once you have the hammer, reinstall that screw a little bit, but not all the way through, and attach slide hammer to that, and start softy hammering it out. It'll come out. Sounds like your baffle broke, and that's why it's in two pieces. If I'm understanding your post correctly anyways. Once out, you might be able to have it welded back together, or order a new one from Yoshi directly. Once out, you'll probably just leave it out and not want it back in to be honest. It's not that much louder.

Thanks for the fast reply

i didn't hammer anything , I just unscrewed the bolt and the inner pipe was already loose, it just wouldn't pull out of the outlet so had to remove it from inlet.

the same is mentioned above in a few posts. So not sure if the baffle is broke.

I've read the Grom rs9 has a tuneable baffle so can have pipe out, ring in, or all of it out,
Spray Wd40 around that coller
I pulled mine out using the spring tool. It's a tight fit for sure but, it will come out with lube and constant pressure.
Just sprayed it, going to try to take it out tomorrow.
From what I remember seeing, some people say it decreases performance. So should you reset the Ecu after removing the baffle?
