Has anyone ever used these with a MIG welder? ![http://www.jegs.com/images/photos/500/520/520-12101.gif](http://www.jegs.com/images/photos/500/520/520-12101.gif) [http://www.jegs.com/p/Hooker/763776/10002/-1](http://www.jegs.com/p/Hooker/763776/10002/-1) It says that you do not need weld rod, but I have a wire feeder that I could upgrade to MIG if required… I would imagine these are designed for TIG? Any thoughts. If I can manage to get the exhaust on my car done, I may want to do one for the bike as well. ---

they are aluminum. While there are aluminum kits for mig welders, it is an uncommon practice to use a MIG welder for aluminum. Aluminum is almost always welded with a TIG welder. ---

My understanding is that Aluminum does not play nice with steel… Looks like they do not have 2.5" anyway… But I may want to scrap my old turbo header for the flanges and make a new 4-1 header. That might let me use some. ---

where do you see that they are alum? i watched them use these on hot rod TV over the weekend, and they migged the header tubes just fine… from what i saw in the show, they were mild steel… ---

[/quote] why would you need 2.5" ? these are for aligning header primarty tubes… you dont have 2.5" primary tubes on your header… and you dont need these to weld up an exhaust at all… ---

I have never tried to weld anything and figured it might make the task a little easier. I’m not looking forward to running the pipe up and over my rear twist beam. If You paint Aluminized or Mild Steel exhaust pipe, will it last a year or two longer?
