i will have to check if mine is there. i have a little leek when i rev it up to like 7000 rpm's. Can u explane what all is suppose to be there. i know there is a ring that bolts to the engine and then 2 springs hold the pipe on. (i can't remeber what els when i toot it off) i should paint it or i'am thinking about ceramic coating it

I found the cure to a leaky exhaust manifold was to replace it with RPM's machined manifold that uses 2 hi-temp o-rings, instead of the single steel ring that the stock flange uses. I never had much luck in getting a stock flange to seal up for very long, no matter how much hi-temp RTV was used. The RPM flange is a bit expensive, but works! I have one on both of my 250R's and neither leaks a drop.
