That may be trx250r. I know for sure the trx exhaust flange from esr fits the lt with a lil notching of the bolt holes.. Thing is though you have to make sure it will fit the inside diameter of the pipe your using.. My trx flange will not fit in my dg pipe.

Thanks pat, let me know the OD of that esr flange.

Skeans- is that flange you have a stock one? I have a stock flange, but am looking for a better o ring type to give a try.

Well due to the Power Valve (PV) that is a 87+ cylinder and I know Q makes Q pipes for the 87+ 250 and based on the looks of that being aluminum and o-ringed plus set up for the spring hooks I'd say there is a good chance it is off a 250 Q pipe.

Call Matt Shear he makes the Q pipes for Q he might have or be able to get a hold of another one for this bike.

Or if you just need o-rings you can get the Viton -rings off McMaster Carr

I'm in the process of figuring out what pipe I'm going to use on my 86' 250.  I've heard people on here say the ftz pipe has nothing on a q pipe and I've heard they haul azz.  I think Iceracer has run or is running an ftz, but his is a powervalve type.  When I called ftz a guy in the shop answered the phone and didn't really give me the opportunity to tell him what it's for...he just told me to email him.  I honestly will be very glad when I figure this out.
