whats the most aggressive flowmaster muffler? the 40 or the 44 model ?
i have a stock 1966 hemi, its very quite, need some nice sounded muffler, whats your suggestion ??The Super40 is a bigger case than the Super 44, so theoretically quieter (but not much). Any delta muffler will be milder than a non-delta.
If you want the MOST aggressive (really?) that's the super 10 (you'll be sorrrreeeee!)
I'm running the 50series big block, giant case with 3 1/2 in/out. I like the sound. You might also consider hooker aero's. Ran 9s thru aeros with a n/a smallblock.
Cherry bomb extreme are LOUD, and cheap as heck. One chamber, $27, and no packing.
Pretty sure that's Tom Hand's test, a member here,VOETOM. If its not, I'm sure he has something similar. He is THE GO-TO guy here for exhaust info.Not a big fan of Flowmasters - I do like the sound but they don't flow very well.
I don't remember which college in Michigan did this test, but they tested the flow values of the major performance mufflers.
They tested the flow of the muffler vs open pipe.
Here are the results of that testing.

Okay, for something with the same sound as your hemi mufflers, with little more volume, I would get a quality turbo. Triple pass like the hemis, just shorter and (somewhat) louder.Following
As I'm looking for something a little more aggressive than stock hemi mufflers for mine.
Not obnoxious just a little more growl than stock
