Sold the SG/IR which I probably shouldnít have...Iím kicking around the idea of another E46 or something completely off the wall. I donít think the E36 is going anywhere and definitely fills my hard roof raw car needs.

Next set of headers in the works is keeping stock primaries for 8Ē, then 10Ē of 1 7/8 to a custom collector into 2.5Ē outlet to 2.5 sec 1.

Iím in the process of copying your jig. Is it necessary to back purge? I plan to swaintech coat the ones Iím making. Also wonder if I swaintech cost does that avoid having me to backpurge the weld as well.

You need to back purge stainless or it’ll “sugar” and create peaks. Use solar flux B. It’s a powder that you mix with water then brush on. It dries and shields the back of the weld. Works well too.

Also, surprisingly, ceramic spray paint from autozone works as far as durability. I coated welds on my sec 2 three years ago and it still looks like that day.

Thanks! So you just used the flux?

Did you use tri mix gas or an argon/CO2 mix? Those welds look pretty good.

Can you get the insides of the pipes like Swaintech? Wonder if itís even worth it...Iím all about the rattle can if it gets good results.

I used pure argon throughout the entire process. You donít need to weld inside because the penetration makes it in there and the solar flex shields itÖ Thereís a nice low smooth bead inside. And yes I only used the solar flux.

All the welds I did were fusion welds, without any filler. When I was doing the fusion welds I forget my exact settings right now but I know I used a pulse and that was able to pull the Puddle along real easily

TIG? I need to get one. But MIG is so much easier.

Yea TIG, Lincoln square wave tig 200. Really great for the home garage. I tried flux core SS MiG and it was disastrous. Maybe Gas shielded mig will be much better. Iím worlds better with mig but under the right conditions I can tig like a machine.
