350F 2 into 1 exhaust adaptor
« on: October 31, 2023, 12:10:52 AM »
The 1972 megaphone style mufflers on my 350F are solid, nicely chromed on the outside but completely shot on the inside.  Replacement factory-look mufflers are too expensive, if I can even find them.  Does anyone know of a 2 into 1 adaptor that would let me connect 2 standard exhaust on each side to a single exhaust about 11/2” - 2” in diameter?  I would like, I think, to then connect a simple straight through muffle on each side.

"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S. Lewis

Yikes!  I guess I pretty naive about the cost.  Didn't really want to spend $550+ on factory look alike originals, or $200+ on a couple of 2 into 1 collectors.  Maybe I will get my welder brother to make me a couple.  Thanks for the information.
