Chambered exhaust
Guy asked this question over on Classracer.com.
Any copo's have documented factory installed chambered exhaust? |
Re: Chambered exhaust
didn't #3 yellow ZL-1 have chambered ?...the Berger car..didn't Charlie own that at one time?....(as if there is a car he did not own at one time or another !!)

Re: Chambered exhaust
I believe Kevin D's COPO Chevelle was factory documented C Exhaust. Beastly sounding btw!!
|
Re: Chambered exhaust
Yes.

Re: Chambered exhaust
When I had my L78 Camaro SS convertible restored at Bob Harris's Camaro Specialties in East Aurora, NY in 2001, I was looking at buying his Fathom Green, green interior COPO Camaro, with Canadian Docs. It was ordered as L72, M22, Chambered Exhaust and Endura bumper. I wish I had now.

Re: Chambered exhaust
Several COPOs are known to have been ordered with it; however ZL-1 #3 was not one of them. The HP Cars test of it back in '69 had some excellent undercarriage photos showing the standard single muffler/dual resonator system. It was later restored with chambered.

Re: Chambered exhaust
Thanks William.... https://www.yenko.net/ubbthreads/imag...ns/worship.gif
I guess it was later on after it was restored that I saw the chambered on the car.. |
Re: Chambered exhaust
I love the sound of Chambered exhaust in the morning........it sounds like victory.

Re: Chambered exhaust
Only one documented Chambered ZL-1. That was an orange Car. The car is now owned by Ervin Harquail and was written up in a magazine fairly recently.

Re: Chambered exhaust
I have information on one COPO Chevelle having come from the factory with chambered exhaust. Apparently, while it sounded good, it was restrictive and actually hurt power. Our car was loud enough with the standard reverse flow mufflers and they probably hurt performance too.

i am buying one of those for my 2007 GT500 Shelby.
with a factory 1000 watt stereo system i am sure i can make my car sound old school. it will be funny to see the looks on people faces when i go to a cruise https://www.yenko.net/ubbthreads/imag...ns/naughty.gif I have GM chambered exhaust on my LS6 car with headers and nothing sounds better.at the ends of the chambered exhausts INLET and OUTLET there is a factory reducer/washer plate that restricts the flow of the exhaust.when you look indside they kind of look like big metal washers welded on. you can drill them open with a large drill bit to get better exhaust flow and more power. just dont gun it when your around cops as they are very loud. i love the sound as it is very unique and nothing sounds better than chambered exhaust with headers but my neighbours hate me https://www.yenko.net/ubbthreads/imag...s/headbang.gif Look closely at the attached photo,you can see my chambered exhaust looking nasty !! |
Re: Chambered exhaust
I didn't want to hijack this thread until it just about run it's course.
It was brought to my attention recently that chambered exhaust was available on 69 ElCamino's. Has anyone ever seen an original chambered exhaust system on an El Camino? It would have to be different than the Chevelle system, because the frame has a longer wheel base by 4". The tailpipes also dump behind the rear tires, not under the bumper like the Chevelles. I wonder if there were part numbers for Elky chambered exhaust pieces, in the parts books. |
Re: Chambered exhaust
NC-8 was never offered on Elcaminos @ the factory that I can see in any literature.Parts books even specify certain ex. pipes were Elcamino specific...and when Chambered comes up,it states "except Elcamino".

Re: Chambered exhaust
Sorry to hijack this thread even further, but did they make any COPO El Caminos??

[/ QUOTE ] Thanks Rick. I was assuming the Chambered ex was not available. I do have some docs from GM that didn't rule it out, but it also doesn't say it was an option on Elky's [ QUOTE ] Sorry to hijack this thread even further, but did they make any COPO El Caminos?? [/ QUOTE ] Yes they did. I have the only one, and it for sale https://www.yenko.net/ubbthreads/imag...ins/3gears.gif Just kidding. I wish they did. The next best thing is the LS-6 ElCamino. That is a goal of mine, before I'm planted. |
Re: Chambered exhaust
Don't want to hijack either, but my '69 BB Pace Car has Canadian docs showing chambered. Anyone know if there are a lot of BB chambered Pacers out there?
