The "hot spot" should be at the target rpm for that engine. This gives that
engine setup the peak point. That is fine for an engine that has no
interfering space. With our street Imperials that general use cross-over pipe
is the
gap between the engine and the transmission and some times at the rear of the
transmission pan.
When I had the "X" installed on my car he build it so that the center came
together just behind the transmission pan. The rear of the "X" as it expands
is
just ahead of the drive shaft. As it was the vehicle before mine with also
an "X" system was a guy with a '72 Fury III 2 dr powered by a 440 and the car
had the factory's OEM towing package. Any ole way back to Imperials, I have
the same inside diameter from the exhaust manifolds thru the mufflers and
resonators to the rear tip just below the bumper. The rear tips are hooked
much
like a lazy question mark with the stem towards the front and the "C" part cut
level with the ground. Chrysler started this hooked tail pipe style with the
1957 year.
