i have read before that gutting the gats can produce results that are comporable to purchasing MSDS headers (if you get a high flow Y-pipe too)my question is this- i wouldn't be able to do the work myself, so can anyone give me a general idea as to the cost of having the cats "gutted" (i'm assuming this means removed....is that correct?). has anyone done this and had before and after dyno results?thanks
