Need an exhaust kit for my 68.5 swb truck. Bonus pic of my truck

Was wondering if you guys would have any recommendations on some pre bent exhaust kits. I'm tired of scraping my exhaust going over speed bumps so I was looking for something that would come from the headers and up into the frame. Then exit before the rear wheels. I have my own welder so all I would need is the tubing pre bent ...It would be for a swb.. Thanks. Here's a complimentary picture of my truck.
