So….more header talk….this had me scratching my head

Is the pipe length and diameter after the collector the same as with the smaller headers?

old headers were 1-5/8” with 3” collector under chassis.

New headers are 1-3/4” stepped to 1-7/8” with a 2.25” to 3” merge collector and are fender exit. New headers are way shorter the the old ones. I don’t have all the pipes the same length as I made them to fit the car and be able to remove them with engine in car.
