Well I got good news for ya bout the header. My friends just picked up me one up yesterday from pull-a-part.. I am in the process of getting it ready to put in my car.. I'll try to get you guys some figures.. Don't have a local dyno but I'll try to get you guys some 1/8th mile times.. I also plan to hollow out my second catalytic converter and have already removed the air silencer and have put a K&N air filter on my car.

Ok so its been a week. Sorry to keep you hanging but I finally got a couple days off from work in a row for once so I did the swap. I found the swap a little time consuming and with the right tools not too hard. So I coated in Black 2000 degree paint. It had the O2 bung and egr bung. I found that the EGR bung isnt useable unless you get the tube from the ranger also. So I ended up blocking my egr off. I tried to get some reasonable proof of any gains. The first thing I found was the weight difference between the massive mustang manifold and the Ranger steel tube header. I would say that the mustang manifold weighs at least 10-15 lbs more. Second thing I noticed driving was the difference in the way my car launched. Before It use bog down if I launched it from a rev. Now I notice no bog and a pretty nice weight transfer. A little test I also ran was a frequent pull I make from one stop sign to the speed limit sign near my house. Its about a 75 yard distance. I always tried to get to the speed limit of 45 mph from a complete stop. I of course launched the car evertime and would get to 40 consistently. After the swap I made it to 44 mph with no trouble. I hope this helps. I am very pleased with my results ecspecially the tone change in the exhuast. It seems to have a bit lower tone idle or rev. It doesnt have that dreaded ricer wet fart sound.

p.s. didn't hollow out the cats

Better that you didn't hollow them out. It creates a disturbance in exhaust flow.

Oh though I walk through the valley of the rice, I fear no turbo, for torque art with me.

Yeah some back pressure is necessary. I have decided to unblock my EGR because of all the major problems I have been hearing of what it can do.

ok so my next upgrade suggestion is disconnecting the Knock sensor. I have been hearing a lot of doing this on the forums. But never have heard any feedback on it. I heard the sensor kills 2.3 performance but what can happen if you just disconnect it?

the knock sensor isnt for horsepower gains...if you disconnect it you need to know how to manage your engine. the knock sensor senses knock in the engine and adjusts the timing so that basically your driving wont be too hard on the engine. a lot of people disconnect them but just as many peolple leave them alone.

if you really want power look in to buying a great cam and port the head/intake

Huge Myth and Urban Legend that you need back pressure. Look it up.

Ok so I'll leave the knock sensor alone then.. and I really like the idea of a cam swap and ported head. I think im mechanically inclined enough to take on the job. So next question is what kind of cam do I have? I was thinking of getting a mild comp roller cam. but thats about $300. Any suggestions? lift? duration? roller? brand? I want a good streetable cam.

Contact Comp Cams and give them your modifications and what you want and they will recommend a cam and tell you if what you want is possible.

you could check with bo over at bo-port racing (you can also tell him what you got and what your end goal is, and he will tell you your best bet). he's one hell of a guy, with tride and true cams to boot! some very streetable cams with good increases
