I just take a 1/8" or 1/4" steal plate and drill 2 holes in it that line up with the bolt holes that the stock tow hook spot, then weld on a hanger off to the side. When I get back from vacation I will take a quick picture of one.

Its just holding the end of the exhaust. Which would dangle maybe 6 inches further down. 20lbs maybe. Fun fact. Thats actually a wire brush on top of the jackstand, because the jackstand wasn't tall enough.

Nice. Good price. This will literally be on the car once every 2 years.

Axle back welded. Ran my second bottle out of argon. Guess the 2 welds up front wont be backpurged. :(

Clean your tungsten off dude! If it dips its time to stop. ...Unless you didn't dip bad and you don't care what it looks like. ..Then proceed.

I know I'm really bad about cleaning my tunsten.

Yours is too long, I don't have a straight long enough to fit it in.

If you seriously want to get good at it then it's got to be clean. If its balled up and coated in stainless then it changes the way you direct heat to the part and it contaminates the weld. Learning how to control the heat in shitty conditions is great if you want to produce consistent ****. You'll be tackling a new challenge if you want them to look good though. controlling the puddle will be different. You can do this. Take your time.

Especially with aluminum^^^

I clean it if it *****. I get lazy if I bump the tungsten with the filler or something and its just coated. When backpurging I could not get it to look good, but when welding the v-bands with thicker material it was a lot better.

I got good penetration though. That's for sure.

That'll flow. You'll enjoy the v-bands for sure.

I already love the vbands. Going to add another up by the front of the trans, then another when the cat comes.

sometimes I regret doing vbands on my car because sometimes they dont want to lineup quite right and dont seal. And then I deal with normal exhaust flanges on other cars and realize those suck more.

I have the kind with male female mating surfaces. They line up awesome.

Takes forever to weld because I have to do it inch by inch.
