Description
Improves Flow For More Power. Add even more horsepower and torque to your V6 Pony by eliminating those power robbing factory catalytic converters with a brand new MAC Off Road Shorty H-Pipe. This off-road shorty H-pipe when combined with a pair of MAC Long Tube Headers will greatly improve your Mustang's exhaust flow for an increase in horsepower, torque and throttle response.

Muscle Car Rumble. This free flowing Mac Performance Mid-Pipe will not only increase horsepower and torque, but it will also add a deep muscle car rumble to the sound of your exhaust with its classic "H" crossover pipe design.

High Quality Construction. Mandrel bent from durable 2.5" steel tubing so there are no kinks to rob you of power, this MAC Performance Mid-Pipe has been hot-dip coated with aluminum-silicon alloy to aluminize the steel to protect against corrosion and rust.

Application. This MAC Performance Off-road Shorty H-pipe is designed for use on the 1999 to 2004 V6 Mustangs with MAC Long Tube Headers installed in combination with an aftermarket or stock factory dual 1999-2004 GT catback exhaust system.

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

I already said most of the story in the MAC Long tubes review, but it's good to see AM offering these as well. Obviously, this being an off road kit means you're losing the cats, which means 1) It's no ...

  • In order to use this Shorty H-pipe in combo with the Flowmaster GT Catback, you would also need to install the matching MAC Long Tube Headers. This mid-pipe itself will not bolt up to your stock manifolds or shorty headers. Hope this helps.

    Couldn't Be Happier

    I got the Mac H-pipe because it was required for the Mac long tube headers. I am very pleased with how well this bolted up once I had the headers on. I did not have to re-adjust the exhaust towards the rear of the car at all. This was literally a perfect fit in my case. This actually hangs higher than my other H-pipe i had before which I am very happy about. Once I got this on with my long tubes, I was VERY satisfied with the way it sounded.Has a very mean growl to it... If you want to remove your cats, this is the way to go! Thanks AM!

    I already said most of the story in the MAC Long tubes review, but it's good to see AM offering these as well. Obviously, this being an off road kit means you're losing the cats, which means 1) It's no longer emissions legal 2) It's going to be much louder. Unless you have a highly talented shop man who can make their own mid pipe that will fit the MAC long tubes, you'll have to have the off road H pipe to go with it. Again a note about the oxygen sensors: in some cases you'll need to have 2 sets of extenders instead of just 1.

    H-pipe makes a world of difference

    I've already purchased the catted pipes x-pipe foe stock exhaust manifolds and frankly left me wanting more with the raspy tone and less than perfect installation instructions. However I was in luck when I found the Mac longtubes for close to nothing and hence bought the H-pipe to give my sixxer a great muscle car tone and a bit more performance to boot. If you haven't thought of going to longtubes I would suggest that you do it as soon as possible cause the H-pipe really makes the exhaust wake up.

    Pretty good product!

    Good over all prodect. I did however have trouble fitting one of the flanges to the driver side longtube header. The whole for the stud to pass thrue was offset by a quarter inch or so. So I had to drill the whole bigger. After that went on without any trouble.
