I'm not a fan of the chambered on Z28. It's sounds like glass pack with a high pitch pop. I like it on big blocks, as it's much more pleasant to my ear. Flowmaster American thunder with 40 series droning is unbearable. I even put 50 series and still too much drone. I installed a set of cheapie Hush Thrust Turbo mufflers and good to go.

I think chambered exhaust looks great and exotic. Its cool that GM installed that type of system from the factory, but wow, that is a loud exhaust system. I'm still going to look at local car shows to try to hear one in person.

firstgenaddict, I listened to several clips last night of chambered exhaust and non-chambered exhaust. There is something that can be said about the way that chambered exhaust sounds. I realize that it is louder than deep tone, but, the sound is powerful, gut wrenching and compliments what the Z28 is known for, speed and power.

Only ones I have heard sound like glass packs when you let off the gas. Maybe if I were 17 again but not at 70.

It sounds wicked whether through manifolds or headers, I agree with Steve the Big Block esp the L78 sounds exceptionally well with the chambers, however I like the sound from the high revving small blocks as well...

Chamber sounds good when the engine is at full song and high rpm, but around town I got tired of it pretty quick riding in a friends car.  It sounds like old school glass packs to me.  On a fun car seldom driven I could live with it.  Driving it frequently would have me making another choice.  My wife certainly wouldn't stand for it at all, even occasionally, lol.

firstgenaddict, on your recent youtube link. The sound of that chambered exhaust sound like that "Z" is ready for business. Mean and loud.

I have decided to move forward and install the chambered exhaust system on my early produced Z (Oct 68).

After reviewing many "youtube" videos of Z28's with the chambered exhaust system and speaking with Eric gardner from gardner exhaust, I feel its the correct decision.

I now can distinguish the chambered sound from a deep tone sound. Yes, its louder and more crackley, but, its what my Z came with.

Good for you! I would have done the same IF my car had originally come with chambered, because I would then have that "excuse" to annoy my wife and neighbors. When I get the urge to do so, I'll just uncork my headers and prepare to sleep in the doghouse.
I'd like to hear your systems when it's done, if possible!

my car came with chambered exhaust.i remember when new it had more of a popping sound but I think it was due to the smog equipment that was on it. i removed the smog pump and the tubes that went into the exhaust manifolds and i think it removed the popping sound.I liked the sound then and still do now. I replaced the old system with a new stainless system sometime in the early 80's, its still on it and i really like the way it sounds, but thats my opinion.

The chambered system will pop back because there is no equalization through a cross flow muffler, it is a true independent DUAL Exhaust.
