1966 Correct Exhaust

I am restoring a 1966 Convertible 289 2V with Thermactor Emissions built in San Jose and am confused about the original exhaust. I have two basic questions.

1. Which elements were welded and which (if any) were clamped? Y Pipe, intermediate, muffler, tail pipe.

2. Did the original have an in-line resonator before the muffler? When I first got this car, the aging exhaust did not have a resonator. I think it was original but was no longer usable. I have seen comments both ways. Could it be plant or drive-train specific?

Thanks as always for any help.

not plant or drivetrain specific. the only clamp used other than the hangars is where the 'Y' pipe meets the intermediate pipe. all other joints were welded. you do need a resonator.

The amazing Carlite65 has the answer once again. I really appreciate your knowledge and willingness to share. So I guess the old pipes without the resonator would not have been original. I will do it correctly.

Thanks again.

Back in the day of leaded fuel, the burned exhaust gas and water vapor from the air made the exhaust rust through rather quickly. In the Chicago area about every 3-4 year on a car driven often.

I have all the respect in the world for Carlite65 (have met him and will confirm he's a knowledgeable guy, but also a good guy). However, I will offer a differing opinion. The Y-pipe was one piece. The intermediate pipe with welded resonator was the 2nd piece. The muffler with welded tail pipe was the 3rd piece. All 3 pieces connected with Ford horseshoe clamps.
