    Hi. I have a 2001 GT 4.6L with the Magnaflow cat-back exhaust system that bolts up to the factory stock headers. Will my exhaust system bolt right up to these shorty headers? Secondly, from previous purchases from you I have installed the Stack larger flow throttle body, cold air intake and a tuner chip. Will my car require further tuning after installing these headers? Thanks.

    • These headers will be a direct fit to your Mustang and will not require any additional tuning.

      Magnaflow shorty headers

      I got these as a gift they are nice BUT crazy expensive for shorty headers . The aren't gold plated and not as good as long tube which I could have gotten for that price. They do fit well .
