look into a tread stone intercooler. I had a CX racing IC setup and im doing a TT build now, ive done decided to use a quality IC. I dont want any pressure drop. There have been issues with the IC cause a lot of pressure drop. but they work great for a budget build..

You're going to have some pressure drop. It's not a bad thing, it just means the intercooler is doing it's job. Of course, you can have too much pressure drop if the core is too small/restrictive. I wouldn't say Treadstone is a quality intercooler and CX isn't. If anything, Treadstone has slightly better cores. Quality would be Garrett or Bell.

if you cut it, make sure you bead roll the ends. a lot of guys will even spray the ends with aerosol hairspray and it act like a temporary glue. i blew off a coupler at 6psi on a non-bead rolled end. Ive decided im going to use mild steel this time around. itll weigh a little more, not much, but i can get a much tighter clamp force with it, unlike aluminum which starts to oval if you over tighten it. plus mild steel is easier to weld. just my .02. And i would say a treadstone IC is a little better quality..., im going with them because they have a twin 2.5" to single 3" out.
@allout06: so you used mild steel for your intake piping? I've been contemplating this because of my lack of a TIG welder and I hear using a MIG on aluminum is a pain. I could buy a TIG but that would cost most than my Turbo build.
I havent bought my IC piping yet but yes i plan on using mild steel. It might weigh an extra 10lbs but at least itll be easy to weld then i will have it powder coated. Ill b makin between 17-20psi so i really want a good clamping force on the couples and weld it where i can. Welding alumimum for a beigginer welder is very difficult from my understanding. I would do aluminum if i had a way to tack it all together and go have it TIGd, but i dont know how i would tac it
i noticed i started smashing mine when i was tightening them, so i took easy, then ended up blowing a coupler off at 6 psi... so i cant imagine 3x more pressure. im sure if it was bead rolled it would of been ok though.

Definitely, not only does bead rolling give the coupler something to grab, it also adds strength.
It basically is a lip on the end of the pipe. Just like most the vacuum lines on our cars. You can buy the bead maker at harbor freight. Found this.
