baffle removal,Good or bad?

I'm new to this forum and just got my 2014 Honda cb500f, love the bike. Had gsxr750 but wanted something more upright so got the cb500f,so much better. Anyways, have already added after market stuff but was wondering my slip on exhaust has a removable baffle and does removing it cause problems to my engine??? Have read different answers on Google which some say it doesn't effect and other say it does,any thoughts would be great. Thks

removing the baffle will obviously make it louder, it will also allow more gas to flow through the exhaust system, causing a lean condition for the engine. If it is a problem for the engine you can only know by removing the baffle, riding it for a few miles and then performing a plug chop to see how lean it is running, however it usually doesn't cause any harm but it will often cause some popping on deceleration. if it's a removable baffle I would just go and try it, you can always put the baffle back in if you don't like it. It is unlikely to harm the engine.. The best solution is to remove the baffle and then re-tune the fuel injection system to work with the modified exhaust system, due to the better gas flow you will pick up a small (probably only 2 or 3) amount of extra horsepower, add a less restrictive air filter and you might see up to 5hp increase, doesn't sound much but that's a 10% increase and you will notice it, but getting the ECU flashed is not cheap, so I suggest just removing the baffle and see what you think, if you like it then save your pennies and get the ECU flashed at a later date, and if you don't like it, but the baffle back in and you are none the worst for it..
