1983 Sportster XLX.
How important is the exhaust pipe crossover? I'm talking about the pipe that runs between the two exhaust pipes. It runs horizontal. Is it supposed to be open flow in there? Does it have to be there? Are there advantages to having it/not having it? Any info would be helpfull. Thanks.

Exhuast crossovers balance the exhaust flow to help scavange gasses out of the pipe. While not mandatory, it greatly helps with performance and a good running motor
Your bike will make a little more power with it, especially at real-world engine speeds. I've run my '83 XLX with and without it, and I believe the best setup to be the crossover exhaust headers with free-flowing slip on mufflers.
