I am installing the TBR full tarmac exhaust today. Which way do the new header gaskets go?
thanks

Either. I don't think it matters.

Don't want to call your dealer a liar but I don't see how that's possible since they are one piece and crushable. Whatever, but that doesn't make sense.Just confirmed w/ dealer, flat side goes against the head, the little hump goes out, towards the headers/exhaust.
Otherwise you will create an exhaust leak once the head heats up from that microscopic gap!
One end of the gasket has a lip, the copper gaskets they said need to have the flat end against the head, lipped end against the headers.Don't want to call your dealer a liar but I don't see how that's possible since they are one piece and crushable. Whatever, but that doesn't make sense.
I remember when I did my exhaust and put the new exhaust gaskets in I did pause and thought about what direction they should go in. I can't remember what I did in the end so I obviously didn't pay that much attention to it.
The shop manual makes no specific reference to the direction (unlike other parts) so I guess it's not mission critical. Perhaps it's a mechanic thing where it's assumed they know the correct orientation?
Either way, my exhaust isn't blowing so it can't be all bad. We've read about people not even replacing the crush gaskets when changing exhausts. That's a much bigger crime IMO.
From the shop manual:
18 Nm (13ftlb) for the exhaust pipe joint nut
21 Nm (15ftlb) for the muffler mounting bolt
I torqued mine up using a torque wrench with a long extension bar and a universal joint adaptor (the flexible head so that you can get the angle). Undo the radiator mounting bolts to bring the rad forward to give you an extra 10mm to give you that all important space.
Hmmmm lol good point. I'll just see which way they were on the factory exhaust. Carefully. Cuz I know once I remove the headers they will plop right out and onto the ground.And just on a separate note, my copper gaskets were flat as a pancake when I took them out so does direction really matter that much?

Trust me, they wont fall out. They need picking out so have a small pick or flat head screwdriver at the ready.
@miweber929 - worth a move to the exhaust thread?
Happy for this to stay as its own thread. But let's leave it at "gaskets". Exhaust stuff can head over to that thread.

Tons of info on here already, some you’ve even provided, show these gaskets are not mileage dependent at all but are single use, crush gaskets that form to the shape of the manifold and head to seal out any imperfections. Once there are crushed to seal the OEM pipe, they should be replacedconsidering the bike only has 1,327 miles I felt okay using OEM ones.
