1969 X-Pipes

What Makes 1969 Mustang X-Pipes Special?

It would seem to make sense that exhaust gases exiting your motor should be directed to leave the car in as direct a fashion as possible. While this is true, a straight exhaust pipe isn’t always the most efficient way to achieve this effect because of the way gases move in your exhaust system, particularly because of the effect of expansion. Expansion occurs naturally and makes your car’s exhaust want to move left and right, rather than straight all the time.

The X-pipe design was created for use on modern performance cars and high-powered racecars. It’s a variation on the more common H-pipe design that you’ll find on many vintage cars. While the H-pipe allows for some transfer of exhaust from the left to right pipes of the exhaust system, the center section you’ll find on each of the 1969 Mustang X-pipes we carry forces exhaust gases to cross from one side to the other. This creates a vortex effect that helps move exhaust gases away from the motor when it is spinning quickly.

The result of this unique design is a higher-pitched sound and smooth idle — characteristics that differ from the X-pipes cousin, the H-pipe. If you’re looking for a mid-pipe that will complement the high-strung rev-happy nature of your highly tuned street motor or racing motor, an X-pipe is an excellent choice.

Selecting the Right X-pipe Is Key

If you own a 289, 302 or 351 car that uses tri-Y headers, make sure you select the appropriate tri-Y 1969 Mustang X-pipe when making your purchase. Tri-Y headers are similar to long-tube headers in that they provide a longer dedicated runner to unlock more horsepower. While tri-Y headers offer more clearance than long-tube headers, they still relocate the point of connection between your mid-pipe and header collector, which is why this special design is necessary. Take note that some trimming may be required to mount this X-pipe.
