Dumb question but I have to ask anyway. What do you folks use to cut the reed stuffers off the RZ/Banshee intake manifolds, razor knife or dremel? I got careless on the first one I tried and cut straight through the rectangular sealing lip.  :bang:
I know I have to be more careful but maybe someone has a hack to make it easier.

i use an exacto. however, the upp ones dont have the stuffer.  :twocents:

Hi Mark
I assume patience is the key here. Do you just cut them flush or taper them to the inlet?
BTW how well do the UPP manifolds fit?

the upps bolt right on. you need a gasket between them and the cage though.

on the banshee style, i usually cut, them smooth with a sanding drum on a dremel.

1 more question
I already have the Banshee cross over tube so will it fit the UPP manifolds?

I just cut them off with a utility knife leaving a sliver stick up and then hold it up to a belt sander and sand it smooth or.............I take some sticky back sand paper (120 grit) and stick it to something flat like a table top or even a countertop and then slide the intake back and forth on the sand paper until it's smooth. And as mark says, use a gasket between the manifold and reed block as well.

Wouldn't that sand the sealing lip off also?

That's good news, looks like I can salvage the one I cut into the sealing lip. Do you go down to the metal or just until the rubber is smooth and flat?

I take them right down to the metal.
