I'm 2 weeks into ownership on this car and there's a ways to go. It has 2 glass packs, but the routing on the pipe takes it under the differential, slightly left. I can lift the pipe and it hits the diff. So today I had the shop look at it.

Turns out the front glass pack had a pipe shoved all the way thru, making it like no muffler at all. And the glass pack in the rear was turned backwards. So I had them take the front pack out and brought back new pipe, routed correctly around the diff, and attached the rear pack the right way around. It breathes a bit better now, and looks better too.

I would bet that the 1st glass pack with the pipe though it was an attempt at a resonator!

Possibly. It was ugly under there.

Post some pics Davey G.

I don't know if this will help, here are a couple of pictures of my 76 stock exhaust.

Nice pics and good lookin' exhaust. Thanks Michael.
