I had a local shop run new duals on my 68 suburban. From the headers out and angled down behind the rear wheels with “turbo” mufflers. I thought they made a mistake but it was $175 plus tax. I don’t think I could’ve gotten the materials for that to do myself..

To answer your first question though - Yes, you can do a larger single exhaust instead of duals. If your engine is stock you probably don’t need more than a single 3” pipe.
