cool. well my Y-pipe is outta there. i have 2.5" divorced duals from the cats back. so obviously the midpipes are still 2.25. but when i get the headers, i was going to have new 2.5" midpipes fabbed up to use my BBK high flow cats that i have. i have the o2 sensor bungs already. if i do this, what size flange would need to be on the midpipes to meet up to the collectors of the new shorties? and then should i just get some 94-98 BBK shorties and have the inside ceramic coated? i really don't want to deal with LT's in Cali, so this would be the next best thing i think. i really just don't want to put older Ford parts on. i'd rather go aftermarket and spend a little more. but it IS good info for the guys who don't want to spend the money on aftermarket.
