Make sure the exhaust doesn't draft back up into the cab. I think that, and
of course the noise, are the main reasons tailpipes are in the, well, tail.
Question: Are you planning to buy a really exotic stereo to drown out the
rapture of your engine?

The critical design goal is that gas pulses from the cylinders arrive at
the collector equally spaced, so you get good scavenging negative pressure
waves. As headers collect each bank individually, and then 'Y' the two
together, I think the only thing that matters is that all the pipes on each
side of the engine are equal. We're talking pretty short pipes here, so
you're not likely to get to the fundamental frequency of any of the runners.
[If you did, one bank would have a different 'tuned' frequency, which
corresponds to a certain engine speed, than the other. I don't know if that
would cause major problems, although I suspect you'd be alot better off
with an engine controller that managed each cylinder instead of the
collective output. You might run one bank lean, and the other rich...]
My SAAB V4 has siamesed exhaust ports, and I have a custom 'Y' exhaust
that does reach it's fundamental at about 4000 rpm. I think the runners
are 50 or 60 inches long. I don't think you'll find too many V8 headers
with runners that long.

My '93 V8 has a mat under the hood.
