    Hello Inmates!

    Hope everyone is well. I did in fact search the site and found nothing on this particular point. So, if I missed it apologies. Otherwise here we go:

    Does anyone have any tips or tricks to help remove a stock exhaust can from the pipe on a (new to me) 2017 Rallye? I am trying to install racks for the 35L BackCountry from Mosko and I am having trouble removing the exhaust can.

    I removed the three T25 srcrews, the top one above the can (size escapes me) and loosen the 13mm nut so the cuff slides back. I wiggle and cajole as much as I think would be needed to get it to slide off. I don't come BMWs and, while I realise they are tough bikes, I don't want to cause any real damage just wrenching on it with reckless abandon. And before I go down the WD-40/heat avenue I thought I would check with some folks smarter than me. That would be you all.

    Thanks in advance and stay safe out there.

    ^ If you removed both the clamp btw slip-on/headers and top hanging screw, that's all that holds slip-on in place so using some sort of penetrant and rotating slip-on back-'n-forth to break it free is all you'll need to do...

    On my 1150GS I had a tough time getting the stock can onto the DanMoto Y-pipe. Ultimately I used a strap wrench (sold at FLAPS for under $10). When I needed to remove it to add RTV sealant (decel popping) the strap wrench worked perfectly.

    Push up and down as far as possible, then side to side as far as possible, the wiggle like hell and pull. This never fails, though you will need to repeat the process a few times.

    I squirted wd40 on the joints and they come loose easily.

    Hammers and crow bars are perfectly acceptable tools for exhaust work.

    Sometimes cursing violently at the exhaust while wiggling it helps.

    Any curses more effective than others?

    From experience I’ve found an advanced degree in Navy magic words is very effective.

    Make sure it's aligned correctly as it's a very tight fit. Rotate just a little left and right and pull. BFH with rubber if needed and maybe lube

    When you put it back together slather some if this where the exhausts slip fit with the header as well as the clamp screw. It makes subsequent removal far easier. Also works as a gasket lubricant on bikes that utilize the tubular Grafoil gaskets like ST1100’s and many others.

    AS above but I use some high temp copper slip, first time getting the blighter off was tough as hell millimetre by millimetre, once off copper slip makes it so much easier now.

    Along with the copper slip anti seize suggestions I clean the contact areas with scotchbrite before the anti seize and re-fit. Prevention over cure.:*sip*
