Hi there, i know this is sort of a newbie question, but i'm really not sure of what can be made with tubing. I was thinking of a bumper, light/push bar and maybe some step bars, but...i'm not sure how. Or further more, is exhust tubing strong enough, it's stainless steel, so not aluminum...but still, is it strong enough.

you have exhuast tubing and want to make a bumper? i wouldnt do it, exhuast tubing isnt hte right thickness to support being used for something like that

No way is exhaust tubing strong enough to do bumpers or anything other than exhaust. Thats why its called EXHAUST tubing.
