i bought this quad for my girl cause i still love 2strokes and dont have time to keep messing with another 2stroke

 

i have a pro circut t4 on my 03
its very loud and works great if u jet it out

 

don't be lazy. do a search. there is plenty of info on here. if not, type in on the internet "z400 exhaust dyno", there is a CT test on there. It will tell you everything you need to know.

 

I could name probably 20 good brands. They are all very similar. I like the HMF because you can get differnet colour ones. Everyone compliments me on the sound of my Big gun. I like yoshimira, curtis sparks, pulse charger, Rossier,Trinity. Tons more, you can't go wrong really.

 

yoshimira, a full pipe yoshimira.
pulse charger's have been known to fall apart
