Replacement exhaust - 09 TXC 510

I had a little uh-oh and smashed up my stock can pretty good. FMF has one listed for an 09 TC 450. Will it work on a TXC 510 ??? From looking at my manual, it should work....

Thank you

..... don't fit.....

I see you answered it. You can look at the parts fiche , I believe the 510 with its longer stroke has a cylinder spacer or taller cylinder effectively moving the exhaust port on the head up a few mm, messing up the mount points between the 450/510 models.
Check P/Ns of the OEM parts to verify fit.
When I was with that series of engine I was constantly using the parts fiche to check what parts are compatible between the displacement models.
PS the bottom end/crankcase is essentially the same for 250/310 (before X-Lite) and 450/510 of the (older) Ing. Macchi big block engine series with almost all crossover parts.
