I have Magnaflow mufflers which are straight through design and are relatively quiet unless you get on it. I have often wondered what chambered would sound like, hopefully I can find one at one of the local car shows to test hear the sound. Exhaust sound is a real personal preference thing. Personally I love the sound of a throaty cobra, I wish I could get my vette to sound like that.

Are they any loader with headers hooked up to them or dosn't it matter? Hell mine you can't hear anything with the tops off any how do to wind noise whats a little more!!!!!
I would say they would be somewhat louder with headers I have stock manifolds.My Wife complained about $324.00 for the system, but after one criuse in the the car she loved the sound!

Vette(s): 1972 conv., sunfire yellow, blk interior, blk vinyl and convertible top. Off frame restoration with American Speed 383 stroker engine producing 500hp plus a 200hp NOS system. MSD ignition. Hooker super competition headers with chambered exhaust.
I can't tell my car is any louder than a friends which doesn't have headers. This is my first experience with chambered exhaust but I've had several midyear corvettes with side exhaust and I don't think there's too much difference in the noise level.
That being said, I must admit that I just turned 61 and my hearing might not be what it used to be. 
My friends 73 coupe with headers and chambered exhaust was way too loud! He lived in a townhome community and was always getting stinkeye from his one neighbor. We simply added correct 73 mufflers to it, big improvement, still sounds great, too. Me, I prefer the car makes the statement, not the noise from it
. I have headers and duals on one of mine and it couldn't sound any better. On another, simply replacing the cat with a test pipe improved the sound. Ran that one once in the barn with the rear Y pipe and mufflers off but the cat still on. Was almost as quite as normal because of the cat. My motivation for dumping it. Mike

I wonder what a chambered exhaust would sound like with my 454? I am installing a slightly larger cam in it this winter.... should sound pretty darn good I'd think....
right now the car has a pretty quiet set of mufflers on it..... I want my neighbors to know when I fire up the vette!!!!! they sure as heck like to run thier leaf blowers at dinner time!!!
well i run to chambered on my LT-1 pushing 370hp, could be a little more with the vortex heads and elderbrock carb, i just have nothing bad to say about the system

not like I have any friends around here anyway, they all consider me the "army guy with all the cars"... even though I am Air Force and only have a few cars, all GM
I'll see how much $$$ I have left after the engine detail and 454 top end rebuild.
Dave, you're close enough... bring it down for me to hear

Lynne, if you happen to have any sound clips or video that shows what your chambered exhaust sounds like, I would LOVE to hear it.
