I need a 2.5" flange welded to a high flow cat and a 2.5" flange welded onto the other side of the exhaust cut out pipe both pieces welded together of flanged idk. Then most likely the B piping shortened and the flange welded back on. I called a few places locally and they told me they wont do any welding even welding flanges on a catalytic. "The EPA wont let us weld anything onto a cat" Seriously WTF I could run a test pipe if you want lol Anyways any shops you know of or experienced welders on the side would be great.
