New Exhaust System Advice

[Rabbit16v@attbi.com (Rabbit16v)]

There is an ideal amount of back pressure for every motor.  Too much is
restrictive and not enough messes with the vacuum effect or swirl or
something but causes a reduction in power also.  If your running a turbo or
something then it's different but if it's just an N/A motor then there is an
ideal amount you just gotta find it.  So, I wouldn't try the potato idea!

It was because of less back pressure.
If more BP was better, you could get an increase in power by jamming a
potato in your tailpipe.

  I believe he meant "rush out of the valves" not rust but this doesn't make
  sense.  If the exhaust would come out faster it wouldn't cause over
heating.
  What it would cause is an improper pressure causing the exhaust to just
puff
  out without any type of pattern or consistancy.  I had TT system (racing
dp
  and dynocrap muffler) that didn't have enough back pressure because I'd
blow
  the muffler out every few weeks.  Once I got a decent muffler the engine
  pepped up quite a bit.  I can only say that it must of been because of the
  greater amount of back pressure the new muffler created.

  Not sure I understand what you are trying to say, Dan.
  I do think C & C were misquoted.

    Slightly on a different subject but I read a Click and Clack article
where
  they said too little backpressure would cause the exhaust to rust out of
the
  valves too quickly. That could make them hot enough to melt or at least
  warp. This true??!!
