Exhaust o-ring

[grackle]

 I have an fmf SST exhaust on my 2001 YZ250.  I was wondering if oem o-rings and the FMF o-rings are interchangeable.  Aso would anyone happen to know the o-ring dimensions and material.  Thanks for any help.

I can't help you with this specific question, but I've found that if you take the pipe into any decent automotive supply store you can find an exhaust o-ring to fit for about a buck.
Better than o.e.m. too.

i was wondering the same thing about exhaust o-rings. My 95yz250 o-ring is $9 an i wondered if an o-ring would work?

Its best to use an exhuast o-ring as they are heat resistant.
If you can only find a regular o-ring, just coat it with hi temp silicone seal.
