RE: Once and For All 94-98 VS 99-04 Header guide! STICKY!!!
I dont have those specs because:
1.) I am poor
2.) They are not smog legal in Cali
3.) I am poor
You will have greater torque, power and a more broad powerband though, BUT!!!! You need to upgrade your intake to help match the exhaust flow. A lot of people will say dont bother with CAI's, larger maf housings and larger TB's.
Its all part of the big picture, people arent happy with TB's and CAI's and headers because they dont put them all on at one time, that kick in the pants feeling just isnt there when putting them on one by one.
I feel that a NA setup should be similar as listed for bolt ons (No bottom end) assuming you have a splitport.
Intake:
1.) MAC orC&L 73mm MAF kit (You can go bigger but this kit makes it simple.)
2.) 70mm Throttle body
3.) Port matched and ported upper and lower intakes with post removed from intake.
4.) Ported and port matched heads w/valve components of your choice
5.) Cam of your choice or go with Harland sharp rollerrockers (These are geometrically incorrect though they net 10hp)
6.) Rhoads or FRPP best hydrolic roller lifters. These are critical for valve lift, stock experiance catastrophic failure at and above 6200rpms.
Exhaust:
1.) Stock 94-98 3-1 Headers or LT or aftermarket shorties of your choice.
2.) Shop modified 1994/95 H or X pipe of your choice, Federal law says you must have 2 cats.
3.) Mufflers and tips of your choice
Final Step: Get it dyno tuned to optimize performance. Adding a CAI, larger MAF housing, TB or spacer can cause the AFR to go way out of specs.
I havnt mentioned things like ignition or UDP's because that doesnt involve this thread.
That is how I have set up my own engine and have enjoyed the results.

Simple, its more cost effictive to cast an exhaust manifold than have it welded up.
The smaller diameter also allowed for more torque making the car feel more Sporty
Hey what happened up there with that banned person? I didnt get to read the posts o.o'
I thought at first you meant the ban stick was for me and I was like "I just want to help! " LOL
Horsepower wise you probably wont see much of an increase, but its a more cost worth solution to getting aftermarket headers (except long tubes.)
There is more work involved though so that you can use the 94-98 headers like expanding the size of the Y-pipe collectors.
Now I should mention that this information is based on three mustangs. A 1995, a 1996 and a 2000. Things changed a little in 01' and there are chances that the 94/95 X-pipe that I used (That worked great with only $70 in modifications from a shop) may not work on 01 or 02 or 03 or 04 or all.
So as long as you dont destroy your stock exhaust you can have fun and learn something new when trying to upgrade.
As for me and my setup (Again www.youtube.com/CrainRacing no mufflers) I gained some good power, enough to feel it from this modification, but I really needed to get mufflers on it before I felt the power increase. The Torque loss was too great without mufflers causing it to bog heavily.
