Akrapovic baffle removal

[Gridiron]

Hi, I am having trouble removing the baffle from my Superduke GT's Akrapovic slip on can. I've taken out the rubber grommet and the bolt underneath, but it still will not come out. Any advice greatly appreciated, cheers.

When i had an Acra on my 1290R, i too had trouble removing that screw behind the gromet. What i found, or what it looked like to me was, The screw that holds the baffle in, is connected to a rod, and as the screw is tightened, it sheers off, leaving the screw in tight, but unable to be removed, i drilled it, and hit a hex key into the hole, and wound it out. Well that was my acra, yours could be different, I've noticed on my Remus muffler, the baffle is held in by a similar screw, but it has a small spot weld holding it in place solid. (small coal chisel should sort that little fuker out) . Good luck removing it.

It's most likely a tamper proof screw (the little rod nub) preventing a tool from fitting into the head of the bolt. Then. Either an interference fit between the baffle and pipe and or a weld somewhere. Euro 4 rules state that the baffle must be installed in such a way to cause damage to the pipe if removed. Nice ha? I have heard that the slip ons for the full systems are not installed the same way , but they are technically not street legal.

I have been advised locally to take it off and chap it out with a bit of wood! Cheers for the help, I'll let you know how it goes [FLUSHED FACE]

Did you remove the bolt?

[Ravendark]

OK... part No. 61405979000 (the new can), baffle came out very easily
Remove the bolt from the side (be careful not to lose the bolt inside the carbon cap)

I used a big metal bar (tommy bar? not sure of the name) and I stuck a 38mm socket in the end



Put it in the can and with a hammer I pushed it out. 2 minutes job.





No damage to the can. The baffle is quite snug in there

Forgive me for being late to reply to this, only recently joined the group.

So - a couple of quick questions.

1. I am going (or was going) to get the black Akra end can on my GT when I buy it - new next month. I'm not interested in the power increase or otherwise as its powerful enough as it is. Is the sound much different?
2. With the whole end can removed - was it much easier to remove the baffle?
3. Are all after market end cans the same now that Euro 4 is here that the baffle cannot be removed??

One of the things I love about my current bike (Aprilia RSV1000R) is the lovely V-twin sound from two Akrapovic exhausts with the baffles removed.

I can only comment on the sound. It does sound considerably better than the stock can. I haven't heard the Akro with the baffle in though - I bought a used Akro from ebay that already had the baffle removed. It sounds subjectively 'meatier' than the stock exhaust does and is also significantly louder at higher revs even with the cat still intact on the bike. I ended up returning the Akro and bought a Remus, which is smaller, louder, and cheaper. If looks are a consideration though, the Akro is much easier on the eyes than just about any other slip on.
