John:
The car you saw was either Chris Moore's (JK Jackson's wife) black TR6 or
Brian Watts' green TR6. Both are running a single pipe sized to a JK
formula that starts with exaust valve size and ends with the length past the
headers. You might have been looking at mine (carmine TR6) but I have a
4"supertrapp. What you noticed was a horn at the end of the pipe that
somewhat makes up for the fact the ideal pipe should extend some 2 or 3 feet
or so past the back bumper. I think its a fairly well accepted fact that a
properly sized single exaust produces more horsepower than a duel system.
Kaz put this in his writings 27 years or so ago.
