Loud mufflers I mean LOUD
Whats the best muffler that will fit a 72 that will give it the loudest LEGAL sound. I'd run straight pipes if I could. 
I heard Flowmasters ser 40 are good and loud andyone have them and your thoughts.
I don't know why the cops let bikes have open pipes and not some custom cars.
I have a 1999 Yahama Road Star 1602cc with straight pipes and they are about 2x louder than any HD with straight pipes.

Spintech didn't seem to sound that loud.
I like the sound of the Flowmaster 40 ser from what I heard on their web site. The scavengers are what I think I want but don't want a ton of tickets.
If anyone has a set of Flowmasters for anything around a 72 let me know which ones you have and how loud they sound.
Thanks in advance.

some kind of glasspack, the dynomax race bullets are glasspacks with very little glass 
and they are loud, very loud (eben at idle), especially the short ones. I have the short ones and love them. They are excellent for scaring the shi-ot out of people

I run 3" Dynomax Race Magnum "Bullet" eh.. Mufflers.
I don't really want to call them that as they are loud as H#$L.
I like em.
EDIT: Here's a video, exhaust exits out the side in front of the tire. Video was taken from around the 330' mark.

Since I actually drive my car a fair amount, I find the loudness of the muffs to be not the overall issue, but that damn droaning I seem to allways get at 1800 rpm or so, especially if pulling a minor hill at slo speed throug the 'hood'....
drives me crazy....that's why I went back to stock on my '72...
I would love to have a deep bass rumble, loud, but NO DRONE>>>

Then you really want the race bullets, the noise will overwhelm the drone
Where you put the mufflers also greatly influences the noise (drone), if you put them under the rear bumper the whole area where the tank sits will act as a sounding chamber, if you put the mufflers somewhere under the floorboards it will greatly be reduced. The bullets are only a tad bigger in diameter than a 3,5" pipe so you can easily put them under the floor somewhere without worrying too much about ground clearance.

TT, you really sure of that?? the locatiion?? interesting point, makes some sense, I guess....maybe I gotta look at that....
I had a set of bullett red Thrush tubes on there, but they not the typical glass packs in they seemed to have a series of plates protruding into the pipe, around which the gasses passed...probably fairly restrictive, but not as bad as stock, nice sound under the rear bumpers, but it drove me crazy with the droning....
you know, I"m not one damn bit happy with the stockish crossmember I have for the tranny mount, and so forth, need mod hell out of it for exhaust pipes....maybe I should look into your suggestion....any other comments??

Maybe Norval's option is a bit better, the idea of being able to drop the entire thing in 1 piece is starting to grow on me.
The race bullets are very open, just like these (these are the dynomax stainless race mufflers that will be isntalled on the vette)
The race bullets are just like that (perforated tube), just round instead of oval.

TT, that damn thing is nothing but a straight pipe, it won't muffle a bit, I had glass packs before, they loud allright but too droney and sharp sounding, what I want to hear is a LOUD bass rumble, without drone, and higher freq noise...that rapp on backdown say, throttle closed...none of that, keep the sound below say 80 hz and kill anything above it....just as a guess.....

yes the perforated pipe does muffle, it muffles the high pitched sounds and leaves a ground shaking rumble. I'll take a vid of ym truck so you can hear it, will have to put the rear drum brake back toghether first...hold on 
Don't you just love the sight of a real open muffler? It should be possible to look yp the tailpipe and see the exhaust valves

Are you running a crossover pipe? From what I understand it really cuts down on the droan but keeps the rumble, will be redoing my whole exh from headers back and adding a crossover to go with my 40's.
