Headers

I have a 00 v6 with dual divorced 2.5 pipes to dual flowmaster 40 mufflers, I am thinking about adding headers which headers would give me the best sound and hp gain

Best sound? Longtube headers. Better performance? I do not know . Word of caution, if your car is lowered, be careful if you're going with longtubes because they tend to hang lower and may scrape going over speed bumps

I do see that you are new to the site, so welcome! Also go check out YouTube for longtube and shorty header videos so you can decide which one sounds better to you. Also check out AmericanMuscle.com for some helpful exhaust tips!

Do you have an aftermarket mid pipe?
I'm running a MAC catback with Mac shorty h-pipe/no cats and mac longtubes on my v6 and it sounds AMAZING

There won't be a problem adding headers after the exhaust has already been done right?

If I'm not mistaken if you hat cats they will have to come off I think and cut a little on your exhaust

Longtube headers give the best performance and hp gains. If you don't have a shorty mid pipe you can't just add them unless an exhaust shop cuts the cats off and may need to add some pipe to make them fit.

I put pacesetter longtube headers on my car with a. Off-road h pipe midpipe. I have flow master catback. Sounds pretty good at low rpms once you get above 3500 however it'll get pretty high pitched. Longtube definitely better for performance tho. It'll never be a v8

Then shorties are the best way to go unless you really want longtubes, because it will cost a lot more.

No, if your putting longtubes in you have to remove your cats. So if you you do shorties and leave the cats on it will be a lot quieter. Also longtubes will be deeper but shorties do give a bit deeper exhaust tone. I went with BBK ceramic coated shorty headers because I want them to last and keep my cats.

I don't have any proof in-hand, but I've been told by complete gearheads in person that shorty headers really don't offer any gains, unless you get the ceramic ones, then maybe your engine temps will stay lower.

You can relocate the 4 cats. But most people buy 2 shorty cats because you gain more hp. The original cats will have to be put in a pipe bender and welded. With the shorty cats you cut your pipe and clamp them on with the clams included. You can also weld.
If you take it to a exhaust shop the Federal Government requires them to make sure you still have cats.
But you could do it yourself.

Longtubes have best performance and sound, won't pass a visual inspection though if your state does it. Short tubes came stock on 94-98's and don't usually crack. They look a lot cleaner than manifolds and give slightly better performance and sound.

Not to jack the thread, I took my car to the shop to get brakes done and the guy says it looks like I have headers. When I bought the car last summer dealer didn't tell me anything. Just wanna know did ford put some type of headers on our car. It's not chrome or anything. Will try to take pics later today

"Shories" verses "longtubes" can depend on the cubic inch size of the engine, and RPM range you want to produce (more) power in. Shorties work well with smaller displacement engines, such as the V6 in the midrange RPM band. Longtube works good in the upper RPM range for both small and bigger displacement engines. However, engines differ in this "theory", depending on intake and head characteristics.
The best way to know how well your engine will perform to which type (headers) is to gather as many dyno results with both, and compare to what modes (if any) you currently have.
