If your friend is a novice welder and he will use a 110v buzz-box welder, then, no. Take it to someone that can weld and fabricate properly or it could make it worseThanks, it makes sense not to wait until something fails. I tend to catastrophize scenarios, especially after reading certain people's expert opinions on automotive repairs. I simply don't want to f*** things up worse.....the old adage, don't fix it if it isn't broken comes to mind. The evidence is there to do something about it though, and I'm at a good point to do it.
Another factor I forgot to mention and for me to consider is that I only have 110v in my garage.
This is a structural point and the whole idea is to reinforce to prevent a problem, not do a half ass trail repair.
Find a local fabricator that can do it, go through it with them and see if you can come together on a price.
Some exhaust shops have this ability, but they also will tell you they've been welding for years, then put their lowest paid man on it and you end up with crap.
Be prepared to spend $500-$1000 for someone else to do the final welding, even with your help to have it disassembled, cleaned, and ready to be welded.
