Remove baffles for QD Exhaust x Brutale 800

Hello,
i got my QD Exhaust for my Brutale 800 from 3 months, truly i'm satisfied of it ;
now ,i would like to remove one baffles (and maybe i will remove one more and so on ) then when i tried to remove one baffles i saw it was hard to remove the screw and bolt , in fact the screw easy got damaged then i should stop to don't make worse the situation ... before to buy i asked if the baffles could remove and the vendor reply "yes, it is easy to remove".

I would like to know if someone remove the baffles and can give me some suggestion to apply the right procedure as i see not manual online .

Here some photo about the bolt inside the exhaust (near the baffles ) ... in case need more info just let me know.

Thanks

on the newer QD exhausts they used high temperature loctite / silicone based glue to fix the baffles. You have to heat the screw and then remove it.
Please be aware (especially if you use a coated exhaust): your warranty is void once the baffle is removed.

Those pictures show the blind nut inside the exhaust. There will be a hex bolt that threads into that from the outside of the exhaust.

You need to remove the mufflers to access the hex bolt.

of course you can, yet I wouldn't recommend doing so. I had a QD on my F3, lost a baffle because the screw (even though tightened more than I'd usually do) got lost due to the vibrations. If you are not careful you might even lose the tips since it's the same screw holding that in place.

getting new baffles from Italy might involve patience and a lot of mails so think about it

also if you ever remove the screw replace it with a higher quality one, the stock ones really are soft and on the picture it looks like your's won't survive more attempts to unscrew save yourself from all the trouble

@Jayjaycooper: If you haven't already achieved success removing the screws, there are a couple of methods that may work for you on that stripped head.

Douse the threads in a penetrating oil to break the corrosion, then:

I would first try an oversized hex lightly hammered into the offending hole. Use steady pressure until the connection breaks free.

If that doesn't work, you can use a Dremel Tool or the like to "SLOT" the head of the bolt, then use a screwdriver to remove the offending piece.

Curious as to how you get along....

Dear silentservice703,
i appreciate your advices ...already done ...with a bit of effort i could remove 2 baffles , i should cut the first one screw that was broken instead the second one was more easy to remove ... a note about the sound of the exhaust without 2 db killers i could recognise it's really louder !!!

Thanks again for the great support as always.

Cheers

Can I just check with you both - is it just the hex head baffle retaining screws that are glued in, or are the baffles themselves glued in?
