Hey, I have a a 95 mustang with a stock 3.8L v6 engine. I recently had the stock muffler replaced with a 40 flowmaster and the Y-pipe cut and another 2in pipe with flowmaster run. Here's my question...disregarding any legal considerations ;) Can I safely strip the insides of the cats and expect the engine to run ok when I put them back on? All the muffler shops I've talked to say the engine would have to be rechipped, bla bla bla...but I have a feeling that's not quite true Should it change the tone of the flowmasters much? I would hate for it to sounds like a freakin rice burner. :) Any advice would be much appreciated.
tia!
