What style?

lol just a lil tid bit, if your buying headers make sure they clear your plugs/ wires nicely because I just changed mine and it was a BITCH because my edelbrock headers basically covered 2 of the plugs....

I bought the headers from a Ford Motorsport dealer in Texas. The headers are made by Mac Performance and are a direct bolt on. They bolt on direct to the factory "Y" pipe and all.

I have them fitted on there and really got them on without any real problems. One thing though, you have to remove some of the emissions stuff on the passenger side.

Permanantly or just for instalation?


Those are equil length shortys. How is your plug and wire clearance?

 

[Cocoyam]

No, not permanatly, in the kit they have brackets to remount the emissions stuff. well, it's the air bypass valve and hoses. as for the spark plug and wire clearance....beautiful! No problem at all.

Sounds good.:thumbup

Let us know if you do or dont have any problems with leaks down the road.

As far as doing what they say, they will help some. But the real restriction in the exhaust is the factory cats, "Y" pipe, and the small exhaust port on the heads.

how do I add pics to a thread? took some pics of the headers, but can't figure out how to put the pics on here.

 

[Gacknar]

There is a ticky about it in the "Suggestions, Feedback & Site Help" forum.

what was the cost of the headers?
im alway looking at differnt headers. but the price and what there coating is always a determing factor.
are they chrome, ceramic or basic black.

[Cocoyam]

hell that aint bad.
did you use the stock bolts or did you puy the locking ones? i heard that summit sells some locking ones that dont back out. but there like 50 bucks or so

 

[Cocoyam]

I used the hardware that came with the headers......new bolts, washers, brackets, etc.

*CLEAR!* *REVIVED*

I just started getting a lot of money because graduation is coming up. Im definetely looking at getting these MAC headers. Just wondering how they still are doin for you. Also, did they come with gaskets and if so did they hold up well? Or should i go the popular route and get the Mr Gasket?

 

[Clarko]

How do they fit?
I hear of nothing but problems with MAC exhaust products.

I got Flowtech headers at Advance. Full length, basic black coated, and included gaskets for like $150

 

[chevysuck]

My ford racing ones were about $275, you can't really tell that I have them on there until I hit about 3000 rpm on the highway, it feels like some turned on the turbo drive or something even in OD. I plan on doing something about those cats and that y-pipe soon.

so do I, but full length isnt legal in CA.

 

[Greenmustanggt]

does bbk make headers for bronco's? I hear MAC's suck, and i love my bbk's on my mustang

 

[sota701]

I was about to put heat wrap on mine when an exhaust guy strongly encouraged me not to. It seems as the heating/cooling effect can/will cause rust prematurely. After reading the part about 'using this heat wrap will void the header manufacturers warranty' I figured I would figure something else out to keep things cool. So I'm thinking hoodscoop or louvering the hood.
