Catalytic converter delete pipe???

[pimprezawrx]

Have any of you DIY guys made a cat delete pipe for this bike yet? I'm looking for pipe dimensions you may have used successfully. Inner diameters, for both the y-section on the header which needs to be cut AND where it would attach to the STOCK muffler. Thanks for any insight!

Check out the Austin Racing Cut-off System (ACRS). They make exactly what you're looking for, with some neat choices on the exhaust-cone. Add a PC-5 and it is an awsesome power addition, and not difficult to install.
