If you really want to do it right, put on the new exhaust and drive around for a while to break in. Then swap back in the stock exhaust and do three pulls. Swap back to the FI exhaust and do three pulls on the same dyno, same day.

But why go through the expense ... I believe the gains are about 10 WHp for most cat backs on an HR/VHR?
