Hey,

I am thinking aobut buying JBA or Mac headers!

Do you guys know any secret tips for installing them on my 99 4.2?

Which ones are better?

Do you guys know anywhere i can get a good deal on some?

Do they make you lose bottom end HP?

Thanks
Kman

 

Depends on you really...

MAC headers -- $300 and very reliable
JBA headers -- $500 and I've heard good and bad

MAC headers -- take 2 months to come in
JBA headers -- take 2 weeks to come in

I'd get the MAC headers any day over the JBA's because I'm just patient enough.

 

Well...Let me ask you this...are MAC headers ceramic coated? If not, I promise the process to get them done is gonna be 200+ dollars to get done. I love my shortie JBAs. I dont think they are as bad as people think.

i want some part numbers and crap for those MAC headers, why aren't they advertised on their website?

Yeah, where can we find MAC headers for our trucks?

Why does it take 2 months to get them??

Thanks kman

 

Yes, MAC headers are ceramic coated.

You have to call MAC and order them by phone. Trust me, it's not as bad as you think! Just go to www.macperformance.com and go the icon that say contact info and dial the toll free number. You can order them by phone, and from what I hear it's a pretty simple process.

The reason they take so long to get in is because their aren't a lot of 4.2 trucks wanting headers, so they don't have them in stock. They special make them right there after you order them, so you basically get a brand spankin' new product with a gaurantee. The downside is that it take 1 to 2 months for the process to take place.

Garrett, don't get me wrong, I love the JBA's myself. I think they are just fine...just a little pricey that's all.

 

I feel ya....I thought I heard that the MACs werent ceramic coated at that low price...maybe I mis-understood...and that happens a lot.

I'm not sure if they're ceramic coated either. They are coated with something, but if it's a ceramic coating then it's the worst I've ever seen. MAC's are nice (and inexpensive) but they rust relatively fast. JBA's have a much nicer coating on them and will last much much longer, but unfortunately JBA doesn't make LT's for V6 Mustangs

 

In case anybody ever needs headers, etc. coated:

They did a set of old rusted headers for one of my motorcycles. Their work is OUTSTANDING both in quality and service.

 

hey kman i have had both, the jba and the mac's.. go mac's there ceramic coated and in my opp. there much nicer..i didnt install them myself im not that brave. i had a local shop put them on. there well worth the wait.

 

so are you saying they are identical in improvement? How did you test compare each set? Were both sets for the 4.2? Why did you get the jba's, then switch to the mac's??

Garrett

 

BTW Jet-Hot contacted me back 233 bucks to get 4.2 headers coated in the 2000 series and color is Ford Blue :P They also sent me a informative video and catalog and some other stuff.. and a nice personal email too....they will also do you intakes or anyhting you wnat them to for that matter. :P

 

well to be honest i never did any dyno-ing or any scientific research on the matter, i had the jba's and the flanges were cracking so i got the mac's. i did the jbas myself and they were hard to bolt on (in my opp. they bolted on kinda funny) but the guy that put my mac's on said they were just a direct bolt on. and yes both sets were for the 4.2. I just liked the feel and responce after the mac's were on much better than the jba's. I guess its all just a matter of preferance, but then agian not everyone has the $ to go blow on both sets and see which ones they like better.

 

I'm just gonna buy some eggs and put them in the slots where the headers bolt on. Then I can make some chickens.

 

hahah now thats a return on your investment. you invest eggs and get chickens back to make more eggs!!!!
