TTI exhaust muffler option

I haven't seen any photos of the GLHS. I just saw my brother last night and he was telling me about it. I don't know that he has done anything cosmetic to the car yet, just a new clutch, axles, and shift linkage. If I go with him to Thunderhill, I'll take photos.

I had another thought about your mufflers this evening. My friend had glass packs welded into the tailpipes of his 67 Barracuda after he got tired of the resonance. It quieted it way down. You might look into that.

I'd love to do that. But on the Barracuda with tips and a 2 1/2" tail pipe there isn't much of any clearance. I feel I'm as close as I can to the gas tank. And real close to the leaf springs too.

Maybe something with the same OD as a 2 1/2 pipe?

Or maybe something with 1/4" max increase in outside radius?

What about an oval resonator that had a minor outside width the same as a 2 1/2 round pipe???
