Small, usually multivalve engines, many with flat plane cranks will sound considerably different to larger, pushrod engines with different firing orders. I suspect it's a combination of the exhaust design mandated by both chassis' and the fact that the Corvette engines typicallly have higher compression, rev higher, and have cam shafts designed around making them rev higher and the more pleasant sound is a by product.
You can also strap a Flowmaster to anything you want and make it sound horrible. And V8 people love their Flowmasters. I disagree on most non-American V8en using flatplane cranks. I think it's induction noise and general noise from overhead cam setups vs. In today's environment of noise and emissions requirements, a bunch of Webers vs. I don't really like the typical sound of an American V8 blowing through large Flowmaster or similar mufflers.
When I had my old '95 Mustang with pushrod 5. I always thought that car sounded great, but I used a cat'd X-pipe and turbo mufflers which use packing and perforated pipe instead of baffles and walls to manage noise. I don't know what V8's your considering for your car but it doesn't have to sound like your typical American hot rod. Flat plane crank? Nah, not many of those outside Ferrari and the GT I think the newer Mustang sounds pretty good.
The Dodge and GM units sound terrible at aggressive throttle. I said many, not ALL had flat plane cranks. If you notice the AMG cars have been steadily upping the size of their motors and they are sounding more and more American in the amount of rumble and burble.
I had a iL briefly that was a nice engine wrapped around a PITA car to work on, but would be a nice cruiser if you didn't have to fix it all the time. That quad cam V8 was very nice and made some nice noises while pulling to 7 or without complaint. European cars tended to compensate for engine size with more RPM capability due to the emissions and licensing fees there, so that's another reason for the differences in engines.
Because a rpm redline is poopy. Look up videos of cup cars qualifying at Indianapolis. Sound inside the car is different than outside, unless it's an open car. I thought my Ram had a nice rumble with the stock exhaust, but I never spent much time on the outside. Same with the 5. I would agree that most or maybe half of V8 cars with aftermarket exhaust don't sound that great, but it's true of all cars, not just the V8 ones. There was a 70 chevelle yesterday at the gas station, it had a mean lumpy idle, but when it pulled away, it sounded horrible.
I think there are not these 'cut-outs' that even the OEM use, which make the engines sound terrible hollow tinny. Me thinks you need to post video examples of the bad ones and the good ones and see if 'the hive' agrees with you. Those cars from the 60s sounded awesome because they had glass packs. You need some cherry bombs. It is so distinctive even with the factory fitted exhaust or marque.
So why does it sound so much better than a V6? Please explain to an engineering numpty. Not sure but i totally agree! If i could get my V12 to sound like a V8 i probably would ScoobyZoom 6, posts months.
A v8 rumble appeals to everyone because it sounds like the mother's heart beat to a foetus in the womb, so we are all preconditioned before birth to the comfort and security associated with the bass tone and resonance unless it's not your v8 but you live next door to someone who owns a v8 and then it can become a source of intense irritation initially mediated by envy.

One of the great things from Virgina Water was hearing the different cars being driven off Lots of lovely V8s of course, but Tony's Diablo did sound particularly awesome I really do wish my car sounded a bit more feisty!

The difference lies in the type of crankshaft used, either flat-plane crank or cross-plane crank. Traditionally, flat-plane cranks have been used in four cylinder engines but European V8s use it while American V8s use the cross-plane crank. The crankshaft is what is connected to the pistons via a connecting rod and the point of connection is called the crank journal. The positioning of the crank journals are what dictates the firing order of the engine and the type of crankshaft.
When you observe a single bank of an cross-plane crank, the firing order is uneven in spacing whereas that of a flat-plane crank is even. Picture a V8 with its 2 banks and cylinders numbered from 1 to 8, take 1 bank to have the even numbers and the other have the odd numbers. With that in mind, the firing order of the C8 Corvette is and as you can see there are two even numbers following each other meaning at some point two cylinders in one bank of the engine fire consecutively instead of alternating to the other bank thus the firing order is uneven.
The uneven firing order means the exhaust gases leaving the engine are also uneven resulting in a pulse that produces the rumble we know. In European V8s, the firing order is even i. Due to the less resistance as an effect of even exhaust gases, the engine with flat-plane crank can rev to higher RPMs. Each type of crank has their benefits and drawbacks but when it comes to engines its a matter of showing your engineering muscles and reducing the drawbacks.
