common
occurance that when I start my engine when parked next to an
alarmed car, the alarm goes off. :-)
Yeh, those 3/4-race cams and headers have this tendancy to do that . . .
One of my brothers old buddies had his exhaust rigged with a pair of 3"
electric aircraft fuel valves. Switch up on the dash ran the exhaust thru a
Caddie quiet set of mufflers, down and it went out about a foot behind the
front wheels with no restriction of any kind. Not only rather loud, but
shot flame a fair distance.
