I've noticed that quite a few of you have welded your own IC pipes from mild steel mandrel bends. My question to you is, have you experienced any rust issues? I have noticed that, when using the same material for an exhaust system, that stuff likes to rust. Have you gotten any rust inside the pipe? Have you taken precautions such as powder coating or ceramic coating the inside? Is it really as much of an issue as I am making it out to be? Thanks

the exhaust rust b/c of the heating and cooling along with the water contact. your ic pipes will see heat but not like that so you won't see rust on the pipes themselves for a while, the welds will rust once they go thur a heat cycle and are exposed to water. i would just weld them and either powerd coat or spray just so they dont look ugly.

the STAR kit pipes have a light rusting on the inside...that and the "chrome" is flaking.

In the end you will have to coat em too like I do. So just go for it.

aluminzed *sp* from jc whitney and the only spots of rust I have gotten were on the welds I made...if you powdercoated they would likely never rust.

Im getting mine made out of SS hopefully I wont have to worry about it that way.

my pipes from hahn have a little rust where the nozzle of my water injection kit is
i used a wire brush to scrape it out and then some of that ceramic 1800 degree engine paint

sprayed inside of it
