    1 Top Rated Question

    Will these headers work with GT40P heads?

    • Unfortunately, these MAC Chrome Equal Length Shorty Headers will not work with GT40-P. Mac offers a specific header for GT40-P headers, however, they are unequal lengths.

      When the headers came in I was very displeased with the finish. The entire thing is orange peeled and cheap looking and the gasket surface had slag all over and wouldn't seal up to the block. I had to grind and bend and all kinds of things to make them work.

      Great heads you can install your self

      These heads are easy to install, but you will need to do some evaluating and planning before going ahead with the wrenching. While you down on the floor unbolting the headers from your X or H pipes, take the time to replace you engine mounts. Your be glad you did when you start to install your headers (not required but a meager convenience).

      MAC Chrome Equal Length Shorty Headers

      I must say 'wow' Purchased these headers and was shocked to have them delivered the next day - free. Yes. What a difference once installed. Looks perfect, shiny and fits so great on the foxbody. The road test revealed exactly what I wanted to happen. Increased horsepower. And I am so pleased. Time to find another part to purchase from American Muscle.

      Mac equal length shorty headers.

      In my 50 years was the first set of headers that I didn't have to take a ball peen hammer to. Fit was first rate. Do yourself a favor though. Spend the extra 40 bucks and install new motor mounts. Clearance was excellent. They look like a chrome ball of hissing cobras. My Camaro buddies even drooled. Make sure you have a GOOD floor jack. Should sound sweet with my chambered x pipe and dynamax ultra flows.

      Good bang for your buck!

      Small hiccup with initial shipment as the driver’s side header had a manufacturing defect. AM sent a second set out and this delayed my install by a week. All in the equal length headers are a tough install and you'll want spark plug wires with 45 degree boots or you will have wires right on top of a hot header. Decent performance gain when installed with the off road H pipe. Exhaust growl is now real nasty! With weather improving a 70 mile test drive on open highway was completed in 1/2 hour. Thanks AM.

      Gains in power & torque

      As with typical headers, there is a noticeable gain in power & torque over stock manifolds. However I did not realize how much room the equal length header use up in engine bay. It is a tight fit I will more than likely go unequal length or a block hugger type header next time I am looking for a shorty type header. Fitment to engine & stock "Y" pipe was bang on. For those on a budget a good buy.
