Chambered? Are the "off-road" exhaust systems not just straight pipes w/ very low restriction mufflers? Off-Road meaning not legal in some states due to certain state exhaust restrictions, yes? I know that in the '60s, chambered (mufflers) exhaust systems were offered on some of the performance cars, and they had a neat sound. I've also seen "off-road" systems f/ sale by aftermarket companies that were simply straight pipes w/ very low restriction mufflers, which also had a tough sound, but different from that "chambered" sound.

I also know that it's important that everyone have the same understanding of the words and terms we use. I'm not as smart as a lot of these guys, so I have to at least keep the terminology straight.
So..."straight pipes" are just that--NOTHING inside them--just an open pipe.
Mufflers have some type of baffling system in them.
Therefore, if one has "straight pipes" they do not have "mufflers" or "baffling"--of any type. The two are mutually exclusive.
I hope this helps.

I don't know the answer to the OP's question. But I do know the answer to yours, and it's "no."
I also know that it's important that everyone have the same understanding of the words and terms we use. I'm not as smart as a lot of these guys, so I have to at least keep the terminology straight.

I had the N11 option "off road exhaust" on a 67 427/400 coupe. It was an undercar system that had low restriction mufflers. Alot of people confued the terminology with the factory side mount exhaust N14. I have those on my 65 convertible. Factory side exhaust is louder and the off road was louder than a stock system.
Corvette Central carries the off road exhaust for mid years. I don't know if they have an application for C3's. Most that bought them for their midyears really like the fit, sound and quality. You might give them a call.

The off road option when it was available included larger than stock diameter pipes and lower restriction mufflers.
The aftermarket providers might have a reproduction kit you could use.

Unless you're suggesting that someone makes EMPTY "mufflers," with zero baffles, possible to fool state inspections stations?
If that's what you're asking me, no, I have not heard of that.
Again, straight pipes are just that--ZERO flow restriction. Mufflers have baffling/glasspack/some restriction. If empty "mufflers" exist, I'm not aware of them.
Hope this helps.

*You're exactly right. The off-road system had the less restrictive mufflers and straight pipes, THIS COMBO CONSISTS OF THESE TWO. If I say straight pipes and don't mention mufflers, then that's all there is. And straight pipes w/ mufflers is just that, w/ no resonator or converter. So "FOREVER...," YOU'RE WRONG, NOT DIFFICULT. Chambered exhaust/mufflers are not just gutted mufflers, and infact they're packed and formed to make a tough sound. Look it up and you'll have the correct info.

What you're looking for is this:

I have this system on my 1970 L-46 and it sounds fantastic, only loud when you want it to be. Fit is great right out of the box.
This is not a chambered exhaust, nor is it baffleless...the only difference between stock mufflers and N11s is that the former have three baffles in each muffler while the latter have two. The pipes are 2.5".
Let me know if you have questions.

Thanks went to corvette central they have n11 mufflers. now sidepipes or n11s i'll have to think on that. n11 a lot cheaper but sides look nice on my 69 http://forums.covetteforum.com/image...ies/woohoo.gif
