Mike, there was no packing material inside chambered exhaust. Nothing to absorb decibels, just pure tuning. Chambered exhaust creates a soundwave anomaly or tuning effect.

I didn't think there was any packing until I saw the pic you posted. Maybe I'm not seeing it right but doesn't that pic make it look like there's some sort of dark gray packing material between the outer shell and inner perforated tubing? If not, time for me to make that eye appointment :-O.

Isn't that the baffle?

I think it's just the end plate or bulkhead of the inner chambered pipe piece - but I have wondered if there was some fiberglass packing in between them in the original GM pipes.

I have full under car chambered exhaust , there is no packing or baffle in them, just the chambered sections.

Good points. I'm not real concerned about the power just cruising around. I do like the look and am a big "loud" fan.

Does anyone have a ballpark estimate on the cost to replace, paint and install the rear panel for a side exhaust car?

New panel, professional paint and paint matching, and professional install about $1000 total.

You can do it for about 1/2 this if you shop used and do some of the work yourself.

Now the other bodywork and mechanical work to install the side pipes will also cost a bit to do it right. So figure this in also. Then add in the sidpipe and covers costs as well.

Not that it really matters, but is your car a AOS body?? These bodies could not originally have factory side pipes...........so they take large hits in judging, and it could possibly affect resale dollars, although this is unlikely for most cars. But something to consider. I bought an AOS body car with side pipes because I liked the overall car. Side pipes were low on my "wish list". But after 25 years of ownership, I like the pipes and the sound. You probably will also.

That's what I figured in that range. I like the thrill of the hunt so finding a good used one would be cool.

It's not an AO Smith car and other than local shows I don't know that I'll ever really show it. I just got it in April and plan on keeping it unless something crazy happens.

your chance of finding a good used original lower panel is slim to none.

and your car looks great as is

your car does look great.................but would look better with side pipes, and of course there is the sound.

Haha. Thanks! I'm beginning to believe the side pipe part.

I would start with a WTB ad in our C1C2 Section, call David S in California, and also call J&D Corvette in Bellflower, California. Also check Ebay and Craigs List. Carlisle is also coming up soon. He doesn't need a 1966 original glass piece, but a used Shermersheims or Corvette Image would work fine as well.

But I agree, with everyone wanting side pipes on their cars, that rear panel is scarce.

Your car looks great the way it is. The added on kickstands do nothing compliment the basic lines of the car.

Are there things I should look for? (any markings, part codes, date codes, etc?)

My car has the 327/350hp engine.
I like the side pipes a lot. Good sounding, at both slow and highway speeds.

The easy way to identify OEM side pipes: chrome tips (not polished stainless). Not so easy: GM part numbers are stamped on the pipes about 8" below the exhaust manifold mounting flange. Left side p/n GM3877215-2, right side p/n GM3877216-W.

Here are the GM part numbers roll-stamped on original assembly-line Walker sidepipes, and the last of the sidepipe inventory in a GM warehouse in Canada 25-30 years ago.

John,
I think those sidepipes were in Stepinwolf's garage attic at the time, after he bought the entire inventory.

That's correct - he bought the entire lot from GM of Canada. One of the great "finds" of the day!
