best mx exhaust

[TeamOMatic69]

I'm getting my special edition yfz450 tomorrow, and down the road, I am gonna start racing. I was just wondering what the best exhaust for mx is for the yfz. Can anyone help me out or tell me what you use?

Id say it depends on what types of upgrades you will be making mainly to the engine.

i would recommend a yoshi or curtis sparks those are nice pipes, yet there is a pipe called a woods racing pipe, and it sounds awesome they make them for a yfz too, if u put a pipe on itll make ur bike scream
