Search crossovers here and you will find a much more detailed thread. Long and short, crossovers change the sound and can improve the breathing at certain RPMs, depending on type and location. The exhaust moving at the crossover can help pull exhaust out of the next cylinder (improved scavanging I think it's called).
Current fleet (subject to change w/o notice) \'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run. My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787. Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
