I'm looking to purchase some new headers for my 1999 mustang v6, But I have a few questions before doing so, I was looking at this website, one i have bought quite a few items off, and saw a couple of headers on there, my first question was, whats the difference between short and long tube headers? Is there any performance difference? or Noise difference? Also I was looking at the short tube headers, and theres just a HTC coated header, and a HTC Ceramic Coated header, the ceramic coated one is 100.00 more, whats the difference between the normal HTC header, and the ceramic coated? And Last question is, will this make my exhaust sound better? Louder? How much louder? And when im at idle, will it sound alot louder? Cause I reall want more sound at idle, and when flooring it..thanks for the help
Score a set or 94-98 headers. Those will give most power. Creamic coated means that the heat will be kept inside the header and move out through the exhaust system.
Headers won't make it louder cause the V6 already has a "Header-Style Manifold." Want you car louder? But a new camshaft.
Any local engine shop can install one for you. They generally ranger around $200. Thet best sound you can get is a "lopey idle" or wild camshaft. But, my real advice is to consult other people and the companies that sell them to find the right cam for you. You seem to be pretty new to this and a new cam might not be ready for you yet.
DON'T get MAC headers. Everyone who has used them for the 99-up has said they don't fit and the quality is bad. JBA is better. Long tube headers flow better, but you will either get rid of the catalytic converters (not legal for street use). Yes, a stock V6 will lose power with just headers. If you do get a cam, you'll have to get new springs, too. I would look into roller rockers. They give you more power without the expense of a new cam install.
Yeah, I was going to get some headers until I saw the ones on there. They are about the best stock header Ford has ever put on a car. I have heard they are good for 350 hp. I don't know if that is true, but they are good.

Long tubes are generally for high RPM applications. If you're going to live your life one 1/4 mile at a time, get the long tubes -but you'll have to upgrade your valvetrain and increase your rev limiter.
Short tubes are for street applications and will build torque with the corresponding build-up.

BBK has a good rep as well . . .

dude, that is absolutely not true. It's the exact opposite.
LT's are the way to go, wether it's a track car, or street car, LT's will improve HP and TQ. LT's will increase TQ way more than a shorty would ever dream of. I have shorty's but that's only because I have to worry about emissions.
And LT's only delete 2 of our cats (we have 4). So technically you will still pass the sniffer, but you won't pass visual. I have been toying with the idea of LT's so I can get my TQ numbers up.
But a set of headers won't give you any power gains on a stockish car. Wait till you're pushing more power. The consensus is that the stock tubular manifolds can handle up to 300bhp before you need more.
And for a good cam you need to go to Redlined Performance Mustangs. They have a cam that is making awesome power! A couple guys are making upward of 220rwhp with just the cam and no porting! It's the 207/215 cam that I have. Unfortunately I was gonna do that, but then I decided to stroke the engine... now I've got a cam that's too small for what I have. ahh well, still has great driveability. This cam will require new springs though. Here's the website: http://www.rpm-mustangs.com/
The owner is an awesome guy, great customer service. I reccomend him to everybody! A really great guy with an awesome product!
