exhaust
I have a 1992,4 litre, A.W.D. Ford Aerostar. I want to replace the stock factory exhaust system with high performance system. I want to take (2) converters off and replace with (1) converter. I would like to improve the exhaust system and let the engine breath a little better. What should I increase the pipe size too. What high performance cat should I put on? Dynamax super cat, a dynamax flo pro,or flowmaster muffler? Will changes affect the computer. What will be gained by doing this? If anybody has done this before please let me know. Thank you
