I wouldnt, some people have success with those though, It all depends on what you want, if you want that polished aluminum pipe then i guess so. I am going with just normal steel and I am having it power coated. There is a great seller on ebay, do a search on his seller name UBendMan, he can hook you up with mandrel bends that you will need in any size. The rest of the pipe you can probally just buy at a hardware or auto parts store in town. I got all my bends and pipe for like $50 total. And like I was saying all those intercoolers on ebay that are cheap and arent name brand are all the same, so whatever is cheapest i would go with. Some sellers on there mark them up real high
