z 400 exhaust

[raptor684]

I have a 04 z 400 with a slip on FMF on and was wandering if the FMF head pipe would help any or waste of money?

The head only is really needed if your doin motorwork to your bike. Or if you just need that little power to get you by. Try tinkerin with your jet or airbox/airfilter or even a revbox before you see if your gonna get a head. Defnilty go with one if your doin some motorwork though
