Description
More Horsepower And Torque. Replace those restrictive stock factory manifolds with a set of MAC Shorty Headers to improve your Mustangs exhaust flow and increase your horsepower and torque throughout the entire RPM band.

High Quality Construction. Constructed from 1-5/8" mandrel bent 16 gauge steel tubing so there are no kinks to rob you of power, these MAC Performance Headers feature 2-1/2" True Fit Collectors that eliminate the need for gaskets which are prone to leak and blow out. These headers are then completed in a bright chrome finish for good looks and a durable long life.

Application. Designed as a direct bolt on, these MAC Shorty Headers will bolt straight up in the stock location to the factory Mid-Pipe on both automatic and manual 2011 to 2014 3.7L V6 Mustangs to improve exhaust flow and sound.

Technical Note. This MAC Performance product is not legal for use in emission restrictive states.

    Mac headers for 2012 mustang v6

    My son helped install these. The bolts were a headache. We used the Ford studs and bolts. Once done the passenger side leaked and could not stop it. It also was into the starter wires. The connector was out of round is why it leaked. Sent them back and put BBK's on. A thousand times better header set. Happy now as all is perfect. DO NOT BUY MAC HEADERS! Get BBK! American Muscle was spot on helping me. They overnighted the BBK's. Here the next day. How about THAT!!

    Sounds amazing!!!

    I constantly receive comments and shocked responses when I tell people this car is a v6. The sound is just off the charts angry!! Installed the headers in a weekend, but took the time to port match them to the heads and smooth out the internal welds. Matched with a BBK 73mm TB and Steeda CAI, Pypes Bomb deletes, SPC Adj LCA's and FRPP relocation brackets. Car hits hard and pulls dirty right through 4th on Micky Thompson Street Comps 285/35/19's. Highly recommend these headers, and the rest but nothing says 'Crazy!' Like tuned length Crome shorty's on a six!!!! Lol

    High Quality Headers

    I bought these after returning a set of the MAC shorty headers which I had bought on sale. The MAC headers were poorly made, welds were shoddy, interior piping was rough and the bends were not smooth at all. I returned due to a factory error with the flange, but thats another story. The BBK headers were night and day. Great quality, they look sharp, and install was far easier than with the MACs. Plus the BBKs came with new manifold gaskets. I already have a SR Throttle Body Spacer, Roush CAI and Roush Axlebacks, and this header set complimented the exhaust tone nicely, and I definitely feel more response when I put the pedal down. My downshifts used to be crackly and loud but these headers refined the tone where I still get a nice sound in the down shifts but it isn't over the top. Great product, highly recommend to anybody. Dont compromise for a lesser brand get the BBKs!!!

    WOW!

    These headers definitely improved the sound of my exhaust. The sound not only got deeper but also cleaner. They also look great under the hood! A lot of the rasp and pops are no longer there. There was also a bump in power as well. Not exactly sure how much but it was definitely noticeable. I chose these over bbk because of forum reviews and I am really glad I did. Totally recommend getting these shorty headers.
