Look at the difference on the Hondata website between the re-flash with the CAT in place and with the racing header (CAT removed.) Very significant gains. Remember, you will no longer be street legal, much louder and will have a caron colored rear bumper.

I found when removing the catylitic, put 5 coats of wax on your rear bumper. That way when you wash it, the carbon comes right off.
