The 350 in my 67 has true dual exhaust but has glass packs. Its been fun for a couple months.

But I wish I could have quiet, with good flow in a muffler. I researched it a bit and best I could come up with is Walker Dynamax either 17749 ot 17747.

Glass packs are a blast, with the engine idling I can put my hand 5 feet from the exhaust pipe and still feel the pulse,

)

I'm looking for the quietest muffler with the best flow. I'm thinking I might even go stock if it costs me a little top-end HP. thanks for any suggestions
