92 rm125 best pipe and tall seat advice ..

Hi guys im new to the forum and would like some advice ....

I live in the uk and have just got a mint old 92 rm125, the bike has only done around 10 hours in 20 years !!
Im after a pipe for it just to add some flavour, can anyone tell me what would be the best front pipe ? .... i see that you can still buy a pro circuit platinum pipe new.... i would like an fmf gold series but these seem to be harder to find, i can see 93 onwards but no fmf's new for 92's ?.... im heading over the pond to the usa next week for a holiday so would like to get something to bring home..... Does anyone have the pc ? and if so is it a good pipe ?
Any advice on both pipes would be wicked

Allso im looking to see if there is anyway of making the seat higher and flatter as im over 6" tall and sink into it to much !
does anyone no if a tall seat is or was an option ? or does a later seat or seat foam fit ?

thanks alot

Cheers
