Will this fit in my 94 mark VIII? It looks like it will fit perfect but I want some more opinions. Thanks
 
Do you have dual exhaust in it? You'd need to measure to be sure, it may fit if you do...
 
I can get it for $100 brand new. I was going to get a universal magnaflow but I seen this and I heard it works on our marks. I just want to make sure it will work before I go and buy it.
 
damm that sounds brutal!! hope it works out for you
 
im going to give it a try. I know it might be pricey but its actually not a stock gt500 x pipe. I found out its the aftermarket one i posted above and its brand new. Its cattless so i most likely will keep it that way and put some magnaflow mufflers on it. i dont feel like cutting the x to put cats in.
 
I have an actual stock GT500 X-Pipe laying in the trunk of my car. Not sure if what you're looking at will work or not but if you'll just get the actual X, it will. Let the exhaust people do the piping for it.
 
So I went and got the X pipe last night. Looks like it will work perfect. Now I am planning on putting new o2 sensors in when I bring it to get put in. How many o2 sensors do our cars have?
 
^^^ I didn't want to sound dumb about asking how many our cars have lol. I'm pretty sure its 2 but I just want to make sure. The x pipe I bought has 3 holes for o2 sensors.
 
Ok. I see in the search that there are big debates over motorcraft and bosch. I most likely will get motorcraft since they are OEM. What should I do about the 3rd hole for the 3rd o2 sensor that I guess the gt500s have? Nolimit is the 3rd hole for an o2 sensor or am i confusing in for something else? I figured Id ask you since you have a stock gt500 x pipe in your trunk.
 
Do I need the wide band o2 sensor for the x pipe installation or can i just somehow plug that hole?
 
Here I took the picture of my X pipe and put arrows showing where I think my stock o2 sensors that are already in my car should go. The other hole I most likely will just plug to make things easier.

Alright, I'm just taking a big guess here but from what I'm looking at, you'll be plugging all three of those holes up because your 02's are going to be before your high flow cats which are way up higher than what I'm seeing here in this pic. Yes, I would highly suggest going with Motorcraft 02's and you only need two of them. I got mine from rockauto.com for half the price of a local Ford dealer and $20 cheaper than 2 Bosch from AZ.

Some here have never had a problem with Bosch 02's but some have and why chance it when the real thing is out there cheap enough? rockauto will have them to you in 2 days.
 
This is an offroad x pipe so there is not going to be any cats. Since there aren't going to be any cats this pipe still includes the spot for the o2 sensors to still be in place. Now I was thinking, our cars have 2 front and 2 rear sensors right? Could I just do this to get all the front and rear sensors in this pipe, where the blue arrows are put the 2 front sensors in and where the red arrows are put the rear sensors in. I would have to get a shop to make another spot but would it work?

This is all getting confusing but I want to make sure everything goes right when it gets installed.
