glasspacks get there sound from the back pressure caused by the shape and packing where as my race bullets jus flow through and the sound comes from the sound waves not being cancelled out completely.

And just how the hell do you know that, PhD?
Back pressure refers to resistance of exhaust flow at exhaust valve in the head. Although there is resistance to flow in any abstruction in exhaust, be it a bump or a muffler, backpressure refers to the overall ability of exhaust system to flow the exhaust gases.
Your race mufflers and glasspacks dumpen the sound pretty much the same way. Sound is absorbed by material packing around the race muffler or glasspack. What is the type of this material does not matter. What matters is that the sound is being dumpened or absorbed. In a chamber muffler, the sound is actually being canceled.

I have read alot of your posts and quite franky, 90% of the time you don't have a clue what you are talking about
|
Well Franky, I have read most of your posts too, 100% of the time you are stubborn in your believes of how things work. Could it be because you drive a chevy and have dog that smokes?

a muffler is any device that muffles (hence the name muffler)
|
Yes. But there are straight through mufflers, muffler mufflers, and even aquistic mufflers. The latter ones use a mic and speaker to cancel the sound completely. I bet you never even heard of such a thing.

I see, a funny pic of one of my dogs or what car I happen to own currently has so much to do with my knowlage and willingness to help people. Yea I own a Chevy along with a Stang and my wifes VW, in fact in the last 12 months alone I have owned a 73 Cutlass, 95 Impala SS, a pro street 72 Nova and 70 Cutlass vert, all these cars have required work, some of them major chassis stuff and guess who did it, thats right me, when I speak, it's from experiance, not from what I heard or read on some web site or magazine. I've seen the cars on your little site and honestly they suck, you had some beater ex-cop car that you claim laid rubber into 4th gear and survived a spin at 120 mph, what a load of BS, your not fooling anybody here, nobody is really dumb enough to beleive anything you say . Oh yea lets not forget the two NMRA cars I have built and crewed on in the last year as well. So please come back when you actually know what the fuk you are doing.
