today i got a pair of headers and am installing them on the zhp , how much power would they give ? and would they give a nice voice?

Should net about 10-20 whp. Next step is a tune and/or some O2 sensor spacers to keep the CEL off.

Exhaust also?

Also get better intake + high flow throttle body
Headers open these cars up so much. I gained a ton of top end and ended up with 212rwhp on a "mustang dyno" with only headers and a full 3" back.
I really have no idea what I am doing
Probably hard to find info since I doubt anybody only installs that piece. In theory it should smooth the air flow, allowing the air density to be higher as it hits the intake manifold. To me it seems like a part that has to be matched with others so you increase the total gain in the system. That's why I said to pair it with the intake and headers
Changing the TB on a 330 won't do you much good. The head is the most restrictive part of the engine...I'd spend all of my money on having the head flowbench engineered for the most gains with your headers/cams/injector combo. Worry about the small stuff is like a rocking chair...you know the rest.

I've thought about the whole headers thing. I guess that most of you can tell how that ended up. The gains in horsepower are not worth a CEL light, and a smelly exhaust. Not to mention how much rasp these things give out, along with the amount of un-flattering noise that comes from the tail pipe.
All you need to combat the CEL is an Innovate LC-1 wideband o2 sensor. As for the smell...well you just need to make sure everything is sealed up tight and learn to deal with the performance gains
