Jim,
The Flowmaster or Pypes systems really aren't all that hard to install in
your garage. I've done several exhaust systems in a day taking my time and
making sure everything fits as it should.
I put a system on a 72 Monte Carlo with stock manifolds that consisted of a
set of down pipes (from Pypes) that made up the length difference from the
stock manifold to where a typical header would dump out at, then finished it
off with one of those cheap Summit Racing systems. It went OK at best, the
generic Summit kit was not my choice, but the owner of the car wanting to
get it done cheaply.
I put the Flowmaster American Thunder system with the 40 series mufflers on
my 70 back in 2000. It does fit the car nice, no complaints there, just the
mufflers rotted out on the bottom and blew the baffles loose so I need to
replace them. That was a system off a set of Dynomax Headers.
I put the Pypes 2.5" X Crossover system on the Charger. It was one of the
best fitting systems I've ever put on a car...seriously. The only problem I
ran into with it are where the Hooker Super Comp headers dumped out under
the body. They didn't line up with the humps in the trans crossmember so I
had to be a little creative there and use a mandrel bent pipe to complete
the system. I used their Race Flo Mufflers that came with the system.
Overall, the mufflers sound OK at best, and the car doesn't have that MOPAR
sound like it should. I'm considering changing the mufflers out.
On my 86 Cutlass that I put a 350 in and full length headers, I used a
Dynomax dual system designed for G body cars with small block chevy engines.
The system fit OK. I don't like how they get around the fact that G body
trans crossmembers don't have 2 humps in them for dual exhaust. They bend
the pipe around and then try to tuck up back up. That system has been on
that car since 2001 and it's rotting and falling apart, probably in part to
the fact I was driving the car thourgh those wonderful NJ winters for a
couple years until I got the truck. I would imagine the system they have
for 68-72 A body GM would be a tad better in quality.
All of these systems can be installed in 1 day by yourself and as long as
you have certain tools like a pipe cutter or sawzall and some wrenches.
I've had to cut and expand pipes on each of the installs I listed above.

That's one thing about my current system that's
probably working out as a "good" thing- since it's not
sealed real well right now, all the moisture drains
out on the floor in my garage!! 8^]
I appreciate everyone' input on this, thanks so much.
I saw the Pypes setup in either my Jegs or Summit
catalog, and knew nada about their stuff, so it's good
to hear some feedback on it.
And I guess you guys are concluding from me talking
about an exhaust swap, that I decided NOT to trade the
car 8^] The exhaust thing has been the biggest
thing bumming me out about the vehicle, so if I can
get that resolved I think I'll be in a much better
place.
Regards,
Jim

OTOH, I've had Flowmasters on my 69 El Camino for
about 4 years, and
it is a driver that I park on the street and drive
in all kinds of
weather, and everything is fine. No signs of rust or
rot anywhere.
Maybe just the fact that I drive it more often keeps
the water from
sitting in there long enough to do damage. Leaving a
car sitting (esp.
in this kind of weather) is probably bad for just
about any muffler.
Just throwing out an alternative experience. Your
results may vary.
