With everyone asking about Headers lately, I figure we might as well put all the info in one spot. Now I've been reading these threads a lot lately, trying to learn as well, so we'll see how acurate I am with this all. I'm ready to update this a lot. I'm using the Official Exhaust Thread as a template.

Lets start with the...

Let me know and I'll add it!

 

Good choice. Unfortunately I have no info on any of these headers lol. Sry

 

www.scdyne.com makes a header for the 2.0

 

good stuff. thanks this will help a lot. lets hope they get some more info out on these things.

 

Thats a nice looking header they make, could be in my future.

 

Jason smith custom header i have on my car! and megan racing is in R&D process right now (with my header)

 

I personally love how the SCdyne headers look.. I wonder if they perform as good as they look huh?

 

what about TOG. The other guys header. i kno many ppl had issues but it is one that is available. im personally going with the long tube one.

 

TOG header is not available. They went out of business and no longer make anything as far as i have heard.

 

TOG = Crap. No Gasket and Improper fitment.

SCDyne = Last I heard still had fitment issues, need accurate gasket & don't get parts in a timely manner.

Weapon R = Crap, No CAT, o2 Simulator needed and restriction after the collector.

CTI = ?? Not sure.

GMPP Mainfold = Good for what it is but doesn't yield as great of results for the price you pay.

Vibrant = Nice but VERY expensive setup.

 

I have the CTI and am very happy with it. If there is a way to convert mustang dyno numbers to dynojet, I can report gains. but I didn't like the guy i did my base dyno at, so Rev it up dyno'd my car this past sunday. with the CTI header and downpipe.

 

I know that JBP will be makeing a 4-1 shorty and a 4-2-1 long tube 3" with cat. similar to Vibrants.

but it will be pretty pricey too because of the T304 Stainless.

 

Thank you! Hope they make one soon!

 

i think for the price and everything the weapon r header seems the way to go. never buy a header that isnt t304 stainless. they do not last. (even ceramic coating falls off after 3 to 4 years).

 

You have any fitment issues or anything with it when you installed it? Do you think it is worth the money cause Im looking at getting one of theres.

 

One thing that's intersting to note about Doc's numbers, he didn't go to redline. Had he gone all the way to 6500 rpms, his gains would've been a little higher. Also, people that have a 7K redline will benefit even more. Good thread!

 

Thanks everyone so far. I should have noted before that when I did this I was on my laptop in the basement, and didn't have a mouse or my usual set of favorites. So I only headed to a few sites, so I don't have all the notes done yet. I hope to figure out what each is made of, 4-1 or 4-2-1, size of collector, if it includes downpipe and/or cat, direct bold up/welding required, and more stuff like that.

The other thing would be prices. If anyone finds these parts any cheaper let me know and I'll update the sites.

 

I heard SCdyne has "fixed" their issue since last time. I will be calling them up this summer and talking to them about their fixes and perhaps even buying one because I do not want to spend more than $500 on a 4-1 header. I would want a 4-2-1 header but I want my cat as well.

 

the only fitment "issue" i had. would be the holes in the flange not lining up "perfectly" but I was also doing it on the drivway layng on the ground.

I couldn't get the driverside most stud to line up and come through. so I pulled it back out, and lined the old gasket up with the holes. it was the tinyest bit off. I just took a drill with an auger bit and took a tiny bit off the side. it went on no problem after that.

The bolt placement on the flange that meets with the downpipe was a bitch to get to, since i was laying on the ground, and it is on top of the pipe.

I tightened it down as best i could on the ground, then drove it about 100 miles.

During the 100 miles it started to leak a small bit, so I retightened everything, wich I expected to do anyway. and now no problems since.

 

hmm, so bolts directly to the stock downpipe huh? (meaning the scdyne)

 

I am suppost to be doing the dyno numbers on the Hahn header and 3inch exhaust this thursday. I can let you guys know the gains from both of those then.

 

If everyone is worried about the cat then just buy an o2 simulator

 

from what I've heard so far an 02 simulator doesn't work right on our cars

 

Nice....most people dont know about cti since its just a small shop up here in NH.....nice to see that someone has it, I've only heard good things about them.

 

One site I check out often but never see them mentioned much here? http://cobalt-addiction.com Prices are pretty good, check out exhausts too! Now their service or stock I cant comment on b/c have not purchased from them yet. But prices are lower, for example....

GMP Extrude Honed Header $279.99

(quality??) Cobalt Pacesetter Header $199.99 / 289.99 Ceramic Coated
