Chambered exhaust
« on: February 25, 2016, 05:00:05 PM »
Looking for comments from anyone that has chambered exhaust system on their 1969 Z28. I am getting ready to order chambered exhaust from Gardner for my early (Oct 1968) LOS produced
69Z. It came from the factory with chambered, so I thought, I would get chambered exhaust again.

I have heard that the Chambered is noisy and tinny sounding. I will be using the cast iron exhaust manifolds. The car is not a show car but will be driven for pleasure and fun.

So, my questions are,

If you have installed Chambered exhaust on your 69Z are you happy with it ?

Would you install a different exhaust system after having experienced the chambered exhaust system performance and noise ?

Thank you

ASM....  you probably got that 'tinny' term from my description of Gardner's exhaust, but I wasn't referring to the 'chambered sound' (I love the factory chambered sound even though it's a horsepower robber).  I was referring to ANY Stainless Steel exhaust as sounding 'tinny'.  that is due to the fact that the metal used in stainless steel exhausts are thinner, less mass, and vibrate/resonate at higher frequencies than does heavier gauge steel (such as is used in aluminized exhaust components).   If you feel the need to install chambered (because your car came that way, or if you just 'love the sound'), there are chambered system manufacturers that make their parts using heavier gauge metal (ie.  Allen's Exhaust and others)...

It appears that most people like Gardners' chambered exhaust due to the ease of fit and correct reproduction. I was leaning towards Gardners' chambered exhaust system due to positive comments from others in the group.

All I have listened to is sound bytes on the internet. I agree it would be better if I could listen to set in
real time.

I've got chambered on my Z (Nov. 68 - LOS) and I had it on a previous 69 big block. The sounds are different, I prefer the big block sound over the small block. The Z seems to cackle more...I know different manufactures do sound different. Don't get me wrong it does sound great. My wife hasn't liked either one! If you are going for driving for pleasure and fun I would go for deep tone system...your neighbors won't know when you start the car up every time! ;D

I'm leaning towards the chambered because my car it came with it. Just listened to several sound bytes on internet. Chambered system is a little loud, but sounds great.

I'm the same way...the car came that way. As far as inside noise, it's not too bad, you have to talk a little louder. It's not as bad as sidepipes on a mid-year Vette.

I listened to deep tone mufflers on internet. They sound good and are a little more quiet. The Chambered system is unique in appearance and may bring more value to vehicle.

Putting my car back together after a project that went far too long. Remember sound of a solid lifter big block thru the chambered. And especially the echoes going on roads with overpasses. It is not supposed to be quiet. That is why it was canceled

Pacecar, are you saying you decided not to install Chambered exhaust because of the noise ?

No - I love the sound.  Run a car with headers thru open exhaust. That is loud but music to some

if all you are going to do is *look* at your car, then a stainless steel system will appear 'new' longer, but if you are going to drive the car, and want it to *sound* original, then a stainless steel system does NOT do that IMO...   Am I the only one who has that opinion??

Is the gardner chambered exhaust a stainless steel system ?
