Back when I had my $50 festiva (yes a $50 car, whole other story there) I tried to go to a few exhaust shops just to get a pipe welded from the cat converter to anywhere protruding from under so I could take it to the echeck station and get a fail sticker. With the fail sticker I could get a t tag and drive it while I fixed it. The first shop quoted me $1200, the second was $800 and the third just laughed and said no. I asked if I could just buy a stick of pipe and the guy said sure, so I drove home in that festiva with a ten foot stick of pipe hanging out the window. I swung by advance to grab a few elbows and headed straight to my garage. With my trusty eBay stick welder set on kill, I welded on a straight piece to extend just behind the passenger door, added a 90 then popped another piece on to let it just protrude from under the car. Total cost was like $30! Best part is, this thing smoked like a diesel rollin coal and used more oil than gas but SOAB if I didn’t roll into that echeck station and it passed!
