This replica exhaust can you match with an TJT or an c16, it is not the most number one exhaust for the manston cylinder or an pro race 2 , better you try an c20 or HR4
thank you.... the threas was older than what is shown... cause in the middle of december i bought a TJT gruppe B....
but now i've just bought a Metrakit Pro Race 2.... and i will get soon a new crankshaft an a new exaust...
Flange Pipe is the piece you put in your whole exhaust. Usually you first put the flange pipe on your cylinder and than you put the whole exhaust on the flange pipe.
