manifolds???
 

anyone know what manifolds these are? they have no markings in them, there light, and the exit to the riser is round.
I need risers for silent choice and would like to know which ones to order.

they are gils..Dependine on which cam is in the engine you may not be able to run the shorter riser

wouldnt the silent choice make the short ones longer?

yes but you will need to worrie about reversion whicj gil;s are known to have a problem with..need to know the cam specs first before you change them..the longer the tube and the further back in the tube where the water blends with the exhaust the less chance of reversion..

this is what you need if you choose to go with the silent choice..
