I have an 05 WR450 with jet kit, Grey wire cut, pea shooter modifies AIS removed, and maybe some other common mods. Other than maybe the pea shooter changed or modified, the exhaust is stock. I am happy with the power of the bike but I would like to give it a little sound. I would like to do this on a budget cause I'm sure if I throw $4 to 5 hundred at this I will easily get what im looking for. So what If I bought one of those mega bomb headers, would that change the sound or do I just need to focus all the $$$ on the slip on? THanks all!
