My TTR is standard but i have a new FMF Powercore (with db killer) , it came with the bike. I'm thinking of fitting it and opening up the airbox and fitting jets to suit. Maybe i'll also get the short header pipe. I'll still run it in standard form for the next few months before deciding to do the mods.
So, is it worth doing ?

My air box is intact so I can still go through deep water. Its nice to have that nice sound isn't it, plus they are a bit lighter and add around 2hp ish too.
