Aftermarket Exhaust

First, I'd buy a Turbine Core, not a Power Core silencer. The Turbine Core is a spark arrestor and the Power Core is not. The Gnarly Woods pipe will give you more low end if you need it. The Gnarly Desert pipe will give you more top end. In my opinion stick with FMF. I've had 5 FMF pipes and they have never failed me. I bought a new Pro Circuit pipe for a KX250 and it rusted out at a weld joint in less than a year. Also, I couldn't really tell any difference other than a little more mid-range boost. My advice for woods riding is a FMF Gnarly Woods pipe and a Turbine Core silencer. You will be pleased! If you want it quiet, go to e-bay and buy a stock silencer cheap. There are always lots of them for sale under motorcycle "parts".

Since it's loud I think maybe your normally quiet pipe has been cut in two, the insulation stripped out, and then welded back together. If so then you've got a good pipe, just need a good spark arrestor.

Maybe someone knows if an '89-94 silencer can be finagled onto your bike. They are effectively quiet, and don't hinder performance worth the noise penalty.

They have a universal s/a for older bikes
