Mac or BBK header Opinion?

[MY 85 GT]

Ok im getting ready for my install on long tubes off road pipe and cat back the place im using wanted to get all Mac the problem is there on nation wide back order...So he said i can go with BBK for the long tubes ...H-pipe and i still can use Mac cat back what do you guys think...Which header is better should i see if i can get all Mac or is it ok to Use BBK and Mac stuff together? Thanks for your help....

The BBk should fit with the rest of the mac exhaust on. I would recommend the BBK over the MAC anyways, I've had both and i don't like the mac, it keeps warping because it isn't a single flange to the heads, causing exhaust leaks, even with copper rtv.

Really the shop that is going to do the work said to try and locate Mac he really said that have a great fit and finish...And thats all he does is work on Mustangs he is a Mustang shop....He said BBK is ok but he perfers Mac I wonder why..I know he said Mac is a true full length header vs. the BBK he said there not a true full length....Im confussed.....

BBK, one piece flange.

MAC stands for MAKE ANOTHER CHOICE

As stated above, the MAC stuff with out a single flange will warp and develop leaks in time. Take it from some one who has them, and cannot wait to get a nice set of Ceramic Coated BBK shorties.

there's a video... read it.. BBK longtubes into BBK H-pipe into flowmasters into flowmaster tails. word.

I'd run BBK long tubes into the BBK H and the MAC catback. If MAC makes a single flange header then go for it, but if they are individual flanges I'd stay away from them.

I like my Mac headers. No clearance issues at all, and no leaking yet, but I only have about 1000 miles on the motor they are on.

Thanks guys for your opinions...I went with Mac..The only reason i did was because the shop doing the work suggested them,and ALL he does is mustangs...And i mean thats all he does...He said they fit well and he really likes them...I hope they dont leak but if they do i guess i'll have to see what can be done about that...I hate header leaks...I will be crazy enough to change them out.....lol Now with that being said how loud will this system be? long tubes..off road H-pipe and Mac cat back.....

loud

Really? cool i love loud exhaust.....lol loud is good as long as it sounds good.....

 

[Flavadave4]

Loud doesn't always= sounds good.

True...loud isnt always good..Yeah i know i have be warned..Well i will see,like i said if they leak they will be replaced.....or he will fix the leaks...Im paying him for the install...

Hoestly if you don't have to take them on and off they will probably be okay, the first time I had to take mine off I had to use a pry bar to get the holes to line up to get them back on. I have never seen that type pf problem with a single flange header.

Let us know how you make out

I've had Mac's on the 90 now for 5 years and haven't had a single problem with them. Absolutely 0 leaks. They still look decent too.

Thats good to hear.... How do they sound? what exhaust do you run?

 

[monte87]

Once you have them on for a while, say a few years-If you need to take them off, Good Luck on getting them back on and aligning them up! Individual flanges are the worst, This is why BBK with a one piece thick flange is simple to put back and align with ZERO issues. But good luck-anyhow, Hope it works out for you!

I went with bassani, equal length ceramic shorty headers and an off road x pipe.
The cat back is flowmaster though and i wasnt impressed with the fit, but it sounds good
