Stealthee Help Please...

I posted on 3si.org about the RippModds headers for the SOHC. Stealthee had said that you have to move the cat back in order for the arrangement to fit. I was wanting to know how much extra work or money that would be. Adding 35-40 horses to my car would be very nice but adding even more money on top of buying $900 headers is really pushing my budget.

Please use PMs for this type of thing.
