I have heard that reeds will not help you out very much....

What you want to do is get a clutch kit for it.

I know they made a twin pipe for your sled but I dont know if they still do. v force reeds will really liven it up.

I would try V-force reeds and a good commet clutch. Pipe will only make it louder!

yes it will make it louder, but it will also make it more powerfull.

Here we go again!!!! Loud vs power... J/K folks.

Seriously, i picked up a Mach Z 800 this fall that had a complete Dynoport setup on it. It was loud so I replaced it back to stock. I see NO difference in power or performance since the change. Stick with the reeds first.

pipes do give you more power, the reason why you might have not gotten noticible gains is cuz they are dyno ports. there are way better aftermarket companys out there.

**smallengineguy** · 05-17-2005, 05:36 PM

The worst part about it, someone paid $1000 for the pipes that were on my sled. That's insane.....

sesnopro · 05-17-2005, 06:39 PM

that is pretty steep, dyno port is the last company I would buy pipes from.
