1. Based on the K&N replacement filter and exhaust (and stickers) my bike is jetted. Great! Except for it's using the loudest muffler possibly built for these bikes. If I drop the full exhaust and move to stock pipe with a slipon, do I have to rejet completely since I do not know what stage is currently installed? I would assume stage 1 or 2 based on the air box still being installed but the assumption is made on limited knowledge.
2. Tires- 150 on the rear is almost new. 120 on the front is trash. Is the difference in handling justifiable enough to replace the rear tire with the front or should I order a front, wear out the rear and then replace with correct sizing?

1. I doubt you'll have to rejet for an exhaust change since you are probably running a non baffled pipe now and most slip-ons are non-baffled also. Check your spark plugs and if the porcelain is chalk white increase the main jet size. The plugs should have sort a rusty color. The slip-ons may not be much quieter. I just installed some Yoshimuras and they are fairly loud at cruising speed.
2. I would stick with O.E.M tire sizes. Oversize tires do you no good whatsoever and your rim width probably won't properly accommodate the extra width. A wide rear tire my increase your testosterone levels but the bike won't perform better. I like to replace tires that match but a different front tire won't put you in a ditch.
