[Tigers] VIN # INFO

[Cullen McCann]

....at least in late model performance like my 5.0 mustang, we have "H" pipes
and "X" pipes...and I think its meant to equalize the harmonics of the exhaust
pulsing between the two banks...which improves exhaust flow effeciency...very
slightly I'll bet. It was said earlier and I'll agree, the engines do seem to
sound alot better with it installed...IMO

pardon my ignorance.  what is the purpose of a crossover pipe between
the exhausts, anyway?
