headers
just got a "new" 96 f150 eddie bauer. im trying to find a set of headers for it, but am coming to realize the 4.9L6 Y is not too common. can anyone tell me where i can find a set, or is this something that is going to have to be completely custom fabricated. any help would be greatly appreciated

Welcome to FTE!!
I say don't even bother - the factory manifolds have pleanty of airflow for that engine and are not very restrictive. You won't gain much if anything from a header swap like you would on a typical V-8 w/ crappy manifolds.
Also, don't forget we have an exhaust systems forum.

Yeah, no one makes headers for the 300. The intake and head flows so poorly that the stock exhaust is more than adequate. 
Most of the guys with carb'd 300s swap EFI manifolds on because they flow good.

its got efi, and i just installed a k&n cold air intake with an airaid throttle body spacer to help it breathe a little better. im just trying to open up the exhaust side more. the plan is to put a full custom exhaust, cut out the cat, n either do a short pipe side exit, or duals out the back. next question, for performance n sound, got any recommendations? ive never heard any 300 with a good exhaust so i have so reference to go off of

Kinda wasting your time..if you want power throw a V-8 in it it's easy enough...
Throw a cat back on it and call it a day. I ran a gibson dual sport kit on my previous truck (95 F-150 300) and it sounded pretty good. It's hard to find a good exhaust for those that don't make them sound like a tractor engine. It's the only kit I have heard that sounds good but my experience is limited with that.
Your typcial glasspacks or the like don't really sound good.

auto zone actually carries the k&N cold air kit, just make sure you specify whether you have mass air or not. that n the spacer got me a tiny bit of low end n about 2 mpg highway. i think itsworth it. spacer was air raid, got it off of autotrucktoys.com. intake was about 150 n the spacer was around 90

Yea
I am the owner of the 81 and It toke a lot of work to get the exhaust to sound the way I wanted it to. It has a good rumble down low and it will cackle when you rack the pipes but it isn't a v8 sound. I did notice a slight power loss when I put extra pipe on over the straigh pipe with a glass pack that it use to have. It is because of the small pipe I used to Y the exhaust under the bumper. Tips make the engine sound better but it never will sound like a v8. the tips give it a deeper rumble down low. They are a very good all around engine. Not a power house but will get the job done and last a long time. The 300 from the factory in this year had factory split manifolds so I can see how the flow wouldn't be a problem.
