well guys im gonna finally start peicing together a turbo setup for my car and was wondering about intercooler piping, Does it need to be bead rolled? My plans for now will only be around 10 lbs of boost. I know i could make the piping myself but im not sure how i would have it bead rolled if this is necessary. I see alot of kits on ebay for DIY but most of the are not beadrolled ends. So i guess my question is how necessary is it cause i should be able to save a decent amount if i can make my own piping.
