No definate number, to many variables but in a nut shell you'll typically get more HP out of an offroad X rather then cats.
The tradeoff is the fact the Offroad has a horrible rasp and loses a little more low end torque but makes up for it up top.

I dont have any dyno figures to refute your statement but I am not sure it is true, that being said there isnt a whole lot of difference from what I have read previously maybe 2-5whp.
I have the cats because I wanted to tone down the volume a bit with my borla exhaust.

not a bad rasp here. we shall see whn i put dumped magnaflows on it next week. but i think it depends on the type of O/R X Pipe you go with.

The difference between the two is ...maybeee 5 hp.Stay catted,help keep our enemies away...and that would be the law enforcements,ministry,government,ect,ect,ect....
Getting tired of all the laws they keep bringing out

are you all talking about stock to a off road X ? cuz mine was like night and day in the HP zone ! the only mod i have done to get a "big" "o hell this was a good mod " reaction from my self...

I actually gained a substantial amount of hp from my x pipe. I dunno how.StangPro said:
Oh, and I have the off-road, and I love the smell a lot better (it is all based on preference) and I love the hallow sound of the exhaust (again, preference).
Most people will tell you to just get exhaust depending on your sound preference:
If you like a hallow ripping sound, get an O/R X. /* some people say it's a bit raspy with 2 chamber mufflers, but I don't know what they're talking about...I thought that's how Mustangs are supposed to sound */
If you like a solid ripping sound, get an X.
If you like a hallow rumbling sound, get an O/R H.
If you like a solid rumbling sound, get an H.
If you like a hallow mix between the two, get a O/R ProChamber.
If you like a solid mix between the two, get a ProChamber.
If I am wrong on any of these, someone please correct me.
i am going with a off road x for mine because i like the sound.. and i dont mind the smell.. thats how cars are supposed too smell.. but a good set of aftermarket high flow cats will loose hardly any HP over a off road peice...
From those that have taken the time to really try and measure HP gain, loss and shift, the difference is maybe 5 HP more. As someone already said, there are too many vairables. For you, an O/R X may do better, because you already have a chip and can take the car back in to be re-tuned so it's not pig rich at idle.
There will probably never be a real answer to this; too much money to prove or disprove. You'd need a 96-98 Mustang, a 99-01, and a 02-04, all stock, and all automatics for consistency. Then you'd need to baseline each on a 1/4 mile. After the baseline runs, start swapping exhaust systems, and re-run each under virtually identical weather conditions. Mathmatically, the combinations of midpipes and catbacks would be mind numbing. But, that would be real-world results; not what a dyno indicates. Dyno's are a great tuning and test tool, but we don't drive our 'Stang on rollers; we drive them in the real world.
