Been looking at putting a full exhaust system on my bike. Either an akra or two brothers havent decided yet. Just woundering if mods can do damage to the bike. Not looking at doing alot of mods just heard if you get a full exhaust your likly to need an ECIII and air filter and remap. Sounds like there could be a few changes being made to the bike. Is all this likley to cause damage down the track or are these basic mods ok and not risky?
