1972 Dodge Colt

Does the instruction sheet list Torqueflites or Turbo 350/400 & Powerglides only?
I like the balance tube between the two cylinders. Guessing that gives it more mid-range torque as opposed to
individual pipes per cylinder for top end.
The window in the back ground makes me think it's the living room...I do see the door opener.
There is very very little difference using a crossover pipe in the exhaust of a motorcycle.
This is mainly helpful in cutting down the decibels, not for torque
