Just go on YouTube and view some videos on what mufflers your thinking about.

I asked my uncle about that after reading this, and he did mention that you don't want to run a large diameter exhaust pipe if you're looking for that "late pipe" roar. I am quoting him directly, he's an old 50's era hot rodder who owns his own collision shop.
That's all I got though, as I am too young to know how to build that myself, but old enough to know exactly what you mean.

That's true, a classic error is to run (too) large diameter exhaust pipe, from what I've read.

My understanding is larger diameter tubing slows the speed of the exhaust gases resulting in a deeper and louder exhaust note. I could be wrong, but it seems to fall in line with what I have seen and experienced on my cars.
Also, lower horsepower motors will tend to have quieter exhaust notes regardless of the muffler or tubing size.

That is an error if the motor makes it's power at lower RPM's. The larger diameter exhaust pipe reduces the velocity of the exhaust gasses through the pipe, thus, reduces cylinder scavenging at lower RPM's. One thing to consider is the diameter of the exhaust should be taylored to RPM range the motor makes it's power in. There's probably more science to it than that.

Well I should be more clear, the exhaust guys say there's no benefit for oversized exhaust pipe? It sounds "better" with the right sized pipes too. I agree that things should be tailored for the intended use. If there's one trend that seems to be somewhat common is peeps bolting on lots of expensive, high performance parts that are optomized for all out drag racing, parts that aren't really very well suited at all for street driving, and just cruising around.
