Question for people who know exhaust!

[MandarinSixSeven]

Hi all,

First off, I must say, my truck has never been all that loud. This is not to say that this is on purpose . The truck has had dual exhaust since the get go, first 1 7/8 now 2 1/4, and 3 different types of mufflers from glasspacks, to cheapy turbos, to now Flowmaster 40 series Delta flows.

My beef is mostly with the sound at idle...it's just too quiet. The engine is quite mild, so far it's just a 350 4-bolt main, edel 1406 carb, HEI ignition, edel performer aluminum intake and corvette style ram horns. At idle is it very mellow, no lump at all and yes it has a wussy cam, but still...I have seen other cars with the Exact same setup that sound a lot lumpier at idle and I don't mean cam lumpy, just the sound of hearing every cylinder fire basically, mines just one steady mellow "flow" of sound.

Can anyone tell me why this would be? I was thinking that it might be due to low compression maybe? Like being that each cylinder doesnt explode at strongly it's just mellow?

I know this sounds kinda funny, but basically what I'm asking is what makes exhaust louder? (other than straight pipes) Because even with the old blown out glasspacks it was not really loud at all...

you thoughts???

thanks
