Hey, me and my friend are looking into wleding up a CAI for my tc. just wondering if anyone has attempted it, and if they have how hard it was to pull off

 

If you want custom, avoid metal all together. The metal tube of a CAI is one thing that takes away from it. Look up G.F.I on yoursciontc (or here I think) if you are wanting to make one. You want to get rid of as much heatsoak as you can. You also want cheap since they provide little gain (even one that eliminates more of the heat soak).
