Make Sure You Have a Perfect Fit

Make sure you measure your headers and know what diameter to use when selecting an X-pipe for your car. In some cases, you may need to trim excess piping to get the perfect fit. We recommend contacting your local muffler shop to perform the trimming if you don’t have the proper safety equipment and cutting tools available.

X-pipes improve your Mustang's performance by forcing exhaust gases from both sides of your exhaust system to mix, smoothing the flow of gasses as they move towards your muffler. When exhaust gasses can exit the car faster, your engine can rev easier and make more power. The design is commonly seen on today’s high-performance sports cars.

Thanks to their aggressive design, X-pipes tend to be seen on cars with high-strung engines. Unlike H-pipes and Y-pipes — the other common mid-pipe designs — X-pipes cater to high-RPM power delivery and tend to deliver a smooth idle. The result is a higher-pitched, exotic exhaust note closer to what you might expect from a modern Mustang than a classic muscle car.

If your car is a six-cylinder Mustang, the unique style of the header requires a specific mid-pipe design to mount properly. Luckily for you, we carry the 1968 Mustang tri-Y-specific X-pipes needed for this application. You can continue creating the dialed-in exhaust system you desire for your straight-six-powered ride.
