I'm attempting to put hard pipes on with the stock CT26 and I'm having a hard time finding a place locally that has the silicon coupler from the turbo to the piping and before I order it online I want to make sure I have the right size... So that's my question what is the right size for the turbo side of the coupler? I'm guessing 2.25 but again I want to be 100% sure before I purchase it.
