Welding Exhaust??

Hey Guys,

So I figured out the 91 header will work with my 89 as long as I buy the newer downpipe.

The only thing I need to do is hook back up the EGR bung.

I was thinking about cutting the bung off my old exhaust and welding it to the new header. Can I do this with my flux core welder? Or do I need special wire?

All I can find on headers are stainless steel. Is my stock 89 one stainless too? Are they weldable? Thanks!

If it's magnetic you can weld to it. Flux core is too general to tell you if you have the right wire, not all flux core is the same. Fluxcore just means the shielding gas is inside the wire or rod rather than the bottle. Is it a MIG machine or stick? You can weld stainless, but not a with a MIG welder as far as I know.

Yes its MIG, wire feed.

Or should I use a different wire?

Stop by a muffler shop. Buy a new bung and have them weld it on.

As long as you're welding steel (not stainless) it should be just fine. Most wire that you pick up at a Lowes, Home Depot, ect is going to be general purpose. Just make sure everything is extremely clean before you go welding with flux core.

And I don't mean for this to come across as offensive, but given that you had to ask basic questions about whether or not you could use your machine and wire I'd assume you don't really have the skill to do the welding you need to do. Like Tim suggested, you're probably better off having a muffler shop do it. It'll cost you a lot less than if you do it wrong and there's a lot of ways for it to go wrong.

Well I've never welded stainless, only mild steel. I'm no professional but I think I do we'll enough as a hobby. That's why I'm asking.

I have to do the repair over a weekend and I'm in a time crunch. My jeep is my wife's only transportation to and from work. So taking the header to a shop wasn't in my time frame.

My only other option is to replace with stock header, or buy the pacesetter repacement?
