I've got a guy that's going to possibly sell me his Hahn intercooler piping without silicone couplers. Can anyone tell me what size/angle and reducers couplers that come with the kit? It will be a little while until I can get it from him, but I would like to buy all blue couplers from siliconeintakes.com This is for the Hahn FMIC piping. Thanks.

I have a brand new (still in the plastic wrapping) set of Hahn IC piping I would be willing to sell you on the cheap. PM me if you are interested.

Off the top of my head, the cold pipe is 2.5" and the hot pipe is 2.25". Both of the smaller pipes are 2.5".

For the cold pipe, you will need a straight coupler for the TB connection, a right angle 2.5" for the main piece to the smaller pipe, and one more straight 2.5" coupler to connect to the IC. For the hot pipe you will need one right angle 2.25" for the turbine connection, one straight 2.25-2.5" coupler for the connection to the smaller pipe, and one 2.5" for the IC connection.

Give Hahn a call and see if they sell replacements.
