These Emgo aftermarket cans (mufflers) will probably work, but since they are generic, rather than dyno tested and test rode specifically for your year and model, no one knows for sure how well they will work (unless they tried this with the same year and model bike, but the jetting still might be different for yours).
My advice is to leave the airbox and air filter stock, then try these exhausts with the stock jetting. You might need to buy a jet kit and do some rejetting to be happy with the throttle response. You might get lucky and your engine runs fine with no rejetting. If you fuck with the stock airbox and stock air filter, you increase your chances of needing to rejet by maybe a thousand million times.
My advice- keep track of the gas mileage after the exhaust changes. Better (higher) gas mileage than stock is usually from running leaner and hotter than stock, possibly shortening the life of the engine, especially if you notice the engine is running hotter than normal.
