When i get my exhaust...since it alluminized we wont be able to weld with a MIG will we or stick weld right? Caust its too hot for the alluminum piping at the joint?

use a tig weld. those are for aluminum.

Aluminized as in just a coating around mild steel? I welded my ghetto downpipe that was aluminized wrinkle bends from Advanced auto with a flux-core unshielded welder. Basically MIG minus the shielding gas. Worked for six months until I just welded up my 3" stainless these past three days.

TIG is a very hard weld to master. For most people, it takes about 5 years of practice before they can weld proficiently. Again I say most becuase there are naturals and such. I would say try what you have and just toy with heat settings and wire feed speed(if you're using a wire feed type).

I thought exhaust systems bolted up...

Well...the cat back does bolt to the cat but i doubt the whole ting comes as one like 6-8+ ft piece... So what about MIG and Stick?

ha nope it comes in a 8ft section. i cant tell you how happy i was to see a guy carrying an 8ft long box that said A'PEXi all over it towards my front door. one gigantic box, one gigantic exhaust.

Oh I though you were doing a custom job or something.

I highly doubt HKS requires welding the exhaust together. My Apexi N1 came in a huge box shipped freight.

Thats awesome...my friend knows how to weld but hes scared of alluminum...i just wouldnt imagine a 8ft box... well maybe i can get the exhaust from whoever was selling it on this forum
