Installing a ETS side mount intercooler this weekend. I'm using some spare 2.25" intercooler piping for the cold-side and want everything to fit snug. What size silicone couplers/reducers do I need for the manifold and endtank? I thought the manifold size was 2.5" and the intercooler side was 2"... Let me know, don't want to waste my money.
