Installing Arrow exhaust on S4R... new exhaust gaskets?

OK, so I'm planning on doing my install tomorrow. Should I pick up new exhaust gaskets?

Re: Installing Arrow exhaust on S4R... new exhaust gaskets?

definitely get the flange gaskets(round ones). when i did mine i had to replace these and i also noticed on the rear the manifold gasket wasn't sealing against the head. checked it and found the head surface was flat and clean but the header was not.i had to use 2 gaskets with exhaust rtv between them to get a good seal. sounds bodgy i know but unless i told you you would never know to look at it.

those things get brittle as h3ll and are a real bother to try to reuse. yeah... see about getting new ones if you're swapping your headers.

I've re-used the exhaust gaskets at the head (formed steel ones) a couple times with no problems.

the arrow exhaust for the s4R doesn't require removing the manifolds from the head so those don't come into play in this case. what derby's referring to are the round gaskets that go between the manifolds and the main header assembly. the s2r/s4r systems don't use a double-slip-fit. they're a single slip-fit which requires those gaskets. and yeah... it sucks trying to reuse them.

Re: Installing Arrow exhaust on S4R... new exhaust gaskets?

Yeah I need some of those mofos too. I thought I had my arrows set after having them chromexed but the leaks are still there. I got three gaskets from BCM Ducati via Mellimoto but there doesn't seem to be alot of them floating around.......and yes they do get destroyed and are not very resuable. I also ordered some of that new exhaust sealing tape. It seems like an 0-ring settup might work better. I know my old RZ with a banshee motor has o-rings at the exhaust head pipes and they seemed to seal up real well.

Anyway...who has the V-donut gaskets DUCSea??

'til you can find replacements, try a nice smearing of high-temp silicone in the slip-fit. not so much that it gets in the way of flow, but a good amount to fill the gaps. should do well in the meantime.

Re: Installing Arrow exhaust on S4R... new exhaust gaskets?

yeah that high temp silicone apparently ain't high temp enough....dried up and flaked away. Maybe the ceramic coated pipes made it worse by holding in more heat at the joint. I was in a pinch the other day with it and actually smeared some JB Weld in the joints and cleaned it off. Thought maybe that would hold me over for a week or two but apparently that too is not high temp enough....burned away like butta......I'm gonna take it apart one more time and hopefully the gaskets aren't destroyed enought to reuse one more time. Somebody on here was reccomending some FMF exhaust tape so I'll give that a try next.

my dealer's parts list didn't list em but we found the st3 ones are the same.and i thought i had to at least loosen the ft. header to slip all the tubing together,but it has been awhile.

Re: Installing Arrow exhaust on S4R... new exhaust gaskets?

(only) one of my local dealers has a few in stock but i wasn't able to make it there before they closed tonight so...

..i went ahead and put the exhaust on anyway. =)

no leaks from the rear and a slight one from the front. took the front apart and tried to make sure it sealed a little better when i reassembled.

then i rode.

i'll check it again tomorrow and if it still leaks i'll get a new gasket.
