FS: ITB'S Envy Motorsports ITB's B16 Type R

I have a set of Envy Motorsports ITB's. Do not take this as a hacked up manifold with some TB's on them. They have a custom CNC machined intake manifold flange with tig welded 2 3/4 aluminum tubes. There are GSXR 750 TB's on these with some velocity stacks. There are no filter on them. These fit a B16 or a Type R head. Im asking 725, or some performance H22 parts. let me know.
