your 0/2 sensors are before the first set of cats...right after the header connection.

correct which means that your 02's are reading the exhuast that comes out of the motor before it ever reaches the cats to begin w/ so weather you have them on there or not it wont make them read any diffrent

No, it won't set off the CE light. I'm always swapping my o/r H to the stock cats for emissions testing and have never had a CE light or any problems at all.

do you know how the 02 sensors come out and did you have to trim or cut your air pump tube at all?

O2 sensors screw in. You can use an o2 sensor socket or just use a tubing wrench so you don't round off the head. You won't have to cut your AP tube if you hang it up before you install the pipe. You can cut the AP tube to remove it when the pipe is installed, just makes it easier. I'm speaking in reference to a 94 5.0.

You mean cutting the egr tube instead of disconnecting it from the stock h-pipe? Why would you do that?

Since you have to put your stock h-pipe on every year, how do you reconnect the egr tube when you go to emmisions? Or do you not hook it up?

I just recently cut the stock tube in 2 about 10" from where it hooks to the stock H. I started taking my car to my buddy's shop which has a lift you drive up on. Well, when we installed the stock H, we forgot to hang the tube 1st. Cutting the tube was the easiest way to get it in on that lift. On other lifts, that lift at the frame, I could just snake it in there. I don't think I'll be able to run the air pump tube now, after my NOVI2000, b/c there's no way I can connnect it now. Hopefully, I'll pass emissions w/o it. In Maryland, emissions is every other year for certain counties.

the check engine light wont come on. the sensor is positioned right after the connection between the exhaust manifold/header and the h-pipe, on the h-pipe tube. the light would come on if you had a 96 or newer mustang, but since you have a 94-95, you are good to go with your h-pipe.

oh my friend put a off road H on his car an said he had to trim that little tube(air pump tube i think) so it would fit right or something, he has a 95 cobra, there was this rubber looking tube that connected to that little tube on the Hpipe an he told me instead he just cut the rubber tube that plugs into it, i have no clue why he had to do it thats why im confused. any of you guys with 94 gt's have to cut anything while putting on a bbk h-pipe?

The air pump tube on my Magnaflow H-pipe didn't fit either, it was too short so I had to rig up another tube to make it fit. Exhaust fitting can be a pain, I wonder how those guys at the factory get everything to line up so well?
