hit a rock in my friends driveway yesterday. did a good bit of damage to the turbo outlet pipe. also dented the down pipe pretty good. 
big rock killed my exhaust
How do you fuck up that badly?
Well there's stainless for you.
Good news is there's a Tig torch right there to fix it.
Try not to breathe while welding that.
I am out of argon. cant weld it till I get a new bottle tomorrow. its when welding galvanized you don't want to breath it in. nothing given off when welding stainless.
I wanna see a pic of the rock!
Zinc will give you fever. I've welded a lot of it. Stainless has chrome in it - very bad.
Breathing none of it is good. But zinc is a mineral in your body. Chrome is a heavy metal poison.

Didn't mean to make the thread more of a downer than it already is. It's really not that much to weld, and the good thing is you have the equipment, which most don't.
levels of are very low and i have ventilation. so its a non issue.
sorry no picture of the rock. lol
i second the pics to this rock! pick up it up and put it on a shelf as a trophy or something, thats one strong bastard lol
got argon today. all better now 
Frankenpipe.
yeah thats not to bad. lol . just one crack all the way around. I had a mild steel turbo mani on my ka-t that cracked several times. it ended up being more weld than pipe.
It would have buffed right out. No big deal. haha
got it all back in today. took it for a test drive . no leaks. no traction at all with freezing road temps.
