    Ok, first of all, are there no O2 sensors bungs in the front? If there arent you need to go and have a shop weld some in, if there are, just connect the sensors and it will solve your problem. The reason the car is running terrible is this, ford dosent just put those sensors in for no reason, they actually do have a purpose. Basically, what they do is measure the exhaust gases for certain things. One is the Air to fuel ratio. So right now, you have no front sensors, and your back sensors are turned off. Now what the computer thinks is that the car is running EXTREMELY lean, because it is not measuring any sort of unburnt fuel in the exhaust, so what it is doing is running very very rich tune to try to correct itself. My suggestion, either hook up the front 02s, or turn the back 02s back on until you can hook up the front O2s, then you can turn them off again.

    Mine was too loud with the o/r H. My prochamber is pretty decent as far as noise goes and gives you "power you can feel", I still prefer a gutted stock H.

    The 2 cats will help quiet the exhaust note down, but it will still be LOUD with those mufflers. That's the reason I went from the american thunders to magnaflows. I guess I'm getting old or just like being able to hold a conversation in the car. :hammer:

    First get rid of those red-neck truck mufflers :hammer:, second I would get a quality X-pipe with or without cats. The mufflers are what is makeing the car so loud (I can imagine what that sounds like ::)) , the 1 chambers is what goes on race cars NOT STREET CARS ;D. If he wants flowmasters get the two or three chambers and it will sound MUCH better.

    hey I'm with you 100% I would go with SLP myself, but I didn't want to throw that out at him in case he is sold on flowmaster products

    okay i stopped reading about halfway through but ive got a stock o/r h with the cats removed and pipe welded back in place of them. i also have the Flowmaster Super 40's... she's not too loud at all, sounds very good. i would just go to a quieter muffler (2 chamber, maybe :dunno:)

    I agree with going with the X pipe. Forget the flows and go with magnaflows. You'll be much happier.
