What Donut gasket & where do I get one???

[Theseminole]

I have a 2009 RS, i bought a Voodoo slip on exhaust and it is too big to fit on to my trike. The dealer said that i needed a oem doughnut gasket, that one came with the trike and if i didnt still have it i need to purchase another one. Can anyone tell me what they are talking about and where can i get one please. TIA!

I dont know what the "doughnut gasket" is, but you should take a closer look to the BRP parts catalog:

http://epc.brp.com/Index.aspx?lang=E...8-667fe6b8cd6a

As product select "Can-Am On-Road", select your year and model, then select "Exhaust System".
Then you should see all the parts the bike had, when it was built and maybe you can also see, what the dealer meant.

Well some times there is a gasket between the header pipe and muffler, it looks like a doughnut with a flat side on it, it sets over the end of the header pipe, flat side towards the engine up ageist a flange, then the muffler will have a ball type of socket that go's over the rounded end of the gasket, and there are springs that hold the whole works together and makes a seal!! I would ask the shop or person that's doing this work what he did with the one he took off???? Looked at that parts break down from BRP and they are calling them slip joints and they don't look anything like I just suggested!! They are the seals between everyone of the connections on your system, you just got to know which one he needs!!! Good luck

If I remember correctly, they were using a Honda gasket. It was alittle thicker.

Not quite the same thing as that one shown in the link above, but if you're looking for the fatter gasket/seal to go between the catalytic converter &/or the bell shaped flared end of one of those pipes, IIRC it's still Honda who does a fat graphite type slip joint gasket that's generally cheaper, more readily available, and fits over the straight pipe to get it to match up to that flared end pipe - altho you might hafta ream its inside/straight pipe bit out juuust a smidge (easy to do, it's a softish graphite material, not steel or even copper/brass.

Can't get a pic to post right now, and JOINT TUYAU*SLIP JOINT 707600650 is all I can see on what's left of the package/cover.... and I dunno if that's a BRP number, a Honda number, or another more generic A/mkt number.

So, apart from asking what happened to the one that came off, that's all I got.

Good Luck!

Hi all have a 2011 RT

What I am looking for is the is the exhaust gasket - between muffler and headers OEM # 514053677 - aftermarket equivalent?

Thanks in advance

You can still get the gasket, why are you looking for aftermarket???

Good morning. Yes, I see that you're in NZ. And Freddy is correct. There was a Honda gasket used on the GS's, between the cat and the headers, because the OEM gaskets were failing. That was not the case with the RT gaskets. They are different. I can't recall anyone having an issue with the OEM gasket that you are asking about. And actually, it goes between the muffler and the Cat, not the muffler and the headers. It is also used on snow mobiles. Typically, if a person is simply replacing the OEM muffler with an aftermarket muffler, that gasket is re-used. Or, just order the OEM gasket and be done with it. You might find a better price on eBay with somebody that ships internationally. 2011 RT. Nice ride.

This thread started with an enquiry about a 2009GS. Totally different from an RT now being discussed.

The GS has 2 gaskets where the engine header pipes fit onto a 2in/1out pipe that allows the muffler to attach

People have replaced the 2 gaskets on the engine side with Honda gaskets because they are much longer lasting.

I gather the OP is looking for the larger gasket on the muffler end of the 2 into one pipe. The OEM muffler is very large and has an integral curved pipe that slides on and over this 3rd gasket.

It depends on how the OP's replacement muffler was attached as to what gasket(s) he needs. I would very much doubt if it would be what is normally called the "Honda" gasket when talking about an '09 GS.

I believe this is the gasket referred to. BRP calls it a seal, #12 on the chart.
Also the 2009 RS has the cat inside the muffler. Replacing the muffler with aftermarket exhaust
effectively eliminates the cat. The muffler connects to a Y pipe that connects to the two exhaust manifolds.
This connection is where we used the Honda gold wing exhaust gaskets because they were more robust. 6500DA70-B17B-404D-A15F-B59323F21A05.jpg
