Welding Magnaflow Stainless

[momsnova]

Hey Guys,

I'm in the process of mocking up a 3" Magnaflow system on my Nova. I'm using the clamps that came with the kit initially but, when its all in place I want to weld the pipes together.

The 409 allow they use can be MIG welded with mild steel wire but I'd rather not do that. A nice stainless exhaust should not have rusty rings.

I have 308 & 309 filler rod, should I get some 409 just for this or will the lower alloy work fine?

I have a MIG and TIG welder in my shop.

Thanks in advance!

I looked everywhere regarding filler when welding 409 and found nothing. Thank you for that article.

I worked at a machine shop and ALL we did was stainless steel. We used 316,304,409, etc... and did all of our tig with 308 rod. At my shop now(www.RustysRodShop.com), the 308 rod is what I use to weld all my stainless exhaust with. I even use the 308 rod to weld clean mild steel. Local Street Rod Shops favor this rod due to the cleanliness of the weld. Hope this helps.
