Any suggestions for a Quiet, High-Flow Muffler? (1 Viewer)

[mrjordann]

Hi, I've got 6-into-1 headers on my 1973 F motor. I want a muffler relatively quiet but something I can hear at idle. Preferably quiet at high RPMs.

But I also would like something High-Flow if possible. Or at least, I don't want a muffler to add backpressure as a compromise for being quiet.

I appreciate your suggestions!

You're looking for something that doesn't really exist. Quiet = back pressure. High flow = louder. That said, I've got a magnaflow 2.5" behind a set of Downey headers and it's got a nice quiet-ish rumble at idle. Not obnoxious at all. It gets a little loud if you're really on it, but not anything I wouldn't want to drive behind if the guy in front of me had the same.
