4-1 exhaust impact on engine..

[Ribo]

Interested in getting you guys opinion on the impact/effect of going from a 4-2 to a 4-1 exhaust on a xj650 maxim and if the baffle/cans makes any difference?

I guess I'm asking if this has any impact on carbs / airflow through the engine?

yes,of course, you will need to do some tuning after a major change
