zo6 vs zr1 exhaust note
Good evening gentlemen, I'm here in Corpus Christi Texas still in a fog over the end of the Spurs game. Man, what a bummer. Anyway, I'm fixing to order a zo6, or a zr1. I've owned a c6,c7, and a c8 zo6 in the past. The exhaust note on the LT6 is what I enjoyed the most about the car. My question is has anyone driven both cars and does the LT7 sound anything like the LT6 at high rpm, or as I've heard, is it true that the turbos take away from the exhaust note. Thanks again for your thoughts

I had a 23 SR with the GM performance exhaust which sounded great, then a 24 Z06 which has a sound of its own and very different then the big block. I now have a 26 ZR1 which is noticeably quiet compared to the Z06 at in town cruising untill you start getting into it, it has a bark of its own when you are getting on it.

Totally different sounds, even with aftermarket exhaust. We've installed virtually every aftermarket combo on the Z06 and have done downpipes/exhaust on the ZR1
No way around it, turbos will always muffle some exhaust volume compared to an N/A application.
You can definitely make the ZR1 sound more aggressive but still falls short of even a stock Z06 IMO. The ZR1 sounds more McLaren-esque
However, the power/tq difference is huge so it depends on what you prioritize

The LT6 is going to rev quicker, due to higher compression ratio (12.5:1)
The boosted LT7 is going to rev slower, due to it's lower comp ratio (9.8:1)
Some drivers love the "change in speed" of a rev. But it this case, it's a false projection of power, as the LT7 far out performs the LT6.

These two guys present good arguments at these linked timestamps. Might be worth rewinding a few seconds for full context of their arguments, especially the second video:
In the second video, it's mostly about how NA cars will hold value over turbo cars. True the ZR1 will always be more expensive the the Z06, all other variables (options, mileage, condition) being equal. But he argues the Z06 may not depreciate as worse as the ZR1. You'd think the ZR1 should hold value due to fewer production numbers. But that's the supply side which covers only one part of the equation. The other part of the equation is demand side. There will be way more Z06 buyers than ZR1 because more people can afford the Z06 while the ZR1 is more cost prohibitive. A smaller pool of buyers for the ZR1 will force ZR1 prices down to where buyer demand exists.

Uh. You sure about that? I don't actually think comp ratio dictates how fast an engine will rev. The rotating mass (eg: FPC) will, and both engines have it. I suspect they'll both rev up just as quickly.
