Pros and Cons of X-Pipe

X-pipes are mid-pipes built with a crossover X-shaped design across an exhaust stream. The X-pipe balances the combustion gases outflowing from the header collector and streamlines exhaust gasses through the rest of the system.

When building the horsepower drag machine, there are various choices you can make. If you’re seeking to have a high-end horsepower in the rpm band, then the X-pipe will be ideal for you. Although most Mustang enthusiasts make choices based on sound, you have to keep power into consideration.



1. Increased speed: More torque and high-end performance in the modern X crossover pipe design boost the car speed thus making the design ideal for high-end exotic sports cars.

2. Performance: It helps in balancing the flow between all the cylinders. The cylinders from the opposite bank of the engine create a negative wave in order to increase the overall flow of the exhausted hand increase the car performance.

3. Exhaust scavenging: X pipe can reduce a lot of popping on deceleration and help in improving the exhaust scavenging to a certain degree.

4. Increase horsepower: X-pipe has two to four times of horsepower than the H-pipe. With X-pipe, gases can be pulled from the exhaust gases cylinder much faster. It increases more power at a higher rpm. The size of the pipe affects the horsepower and torque.

5. More Torque: The x-pipe nets an increase in high-end torque making many performance cars utilize the X design over the standard H design.

6. Less backpressure: X-design allows exhaust pulses to merge at the crossover point to create a smooth flow exhaust that leads to less pressure and more power.

7. Fuel economy: X-pipe performs better with minimal investment in time and it is fuel economical. It gives value to your money.

8. No additional maintenance: After legal modification of the vehicle with custom x-pipes, there is no additional maintenance needed for your vehicle.

9. Easy installation: It is very easy to install the x-pipes, you only need to connect the dots. The front should be welded to the collector pipe while the rear should be connected to the intermediate pipes. It can easily be integrated into the dual existing exhaust system

10. Effective: X-pipe offers both protection and effectiveness. It delivers a low growl in your vehicle and tweaks your horsepower high while keeping the airflow at an optimum level.



1. Cost: The biggest drawback of the x-pipe exhaust system is the cost; you have to tune your vehicle based on the exhaust pipe. If you don’t get the right size, your vehicle may lose piles of low-end torque.

2. Affects driveshaft: A 3-inch pipe affects clearance around the driveshaft. It makes it difficult to install a driveshaft loop in the car without tweaking it especially if you have a smaller car.

3. Loud sound: X-pipe increases the sound of your car engine, it makes the car produce loud sounds and raspy revs. Upgrading your Mustang’s exhaust for more power and better flow affects the vehicle’s sound.

4. Irritation: Although the exhaust rasp is not bad, its constant popping can be very irritating for some enthusiasts.

5. Couple HP: X-pipe configuration may make the couple HP go high up.

6. Increase exhaust flow: The Corsa doubles the Helix x-pipe bolt in place of Corvette’s factory setting leading to increased exhaust flow.

7. Few placement options: The X pipe offers a few options of where it can be placed. A-bodies are not designed to accommodate x-pipe making the transmission tunnel serve as an ideal location for installation.

    You’ve made a LOT of generalizations but have provided absolutely no hard data so support your claims.
    “More torque and high-end performance, The x-pipe nets an increase in high-end torque”.
    “X-pipe has two to four times of horsepower than the H-pipe”? Are you serious or do you just talk without thinking? To clarify what you just said is, if a vehicle with an H-pipe is making 300hp then all you have to do is install the x-pipe and you will make two to four times as much horsepower so 600 to 1200hp? That may be the stupidest thing I’ve read all year!
    If you are going to write articles like this please invest in a shred of commonsense!
    Every single “pro & con” you’ve listed comes without a single instance of proof! Where are the dyno tests, where are the acceleration tests? This is one of the worst written “performance” articles I’ve ever read!
    No, data, no proof, no real world comparisons, just your generalizations and we are supposed to believe it!
    I should go put an X pipe on my son’s BMX bike so he can get four times the horsepower out of it!
    SMH. Great journalism there Urkel!

    Buddy you should re-read the statement and have a rethink.

    4. Increase horsepower: X-pipe has two to four times of horsepower than the H-pipe.

    Mentions nothing about raising HP of the car. If your H-pipe adds 5HP to the car its stating that the X-Pipe will add 2-4X of the H-pipe (5HP)

      Matt is still right about the author making very bolt statements without providing any proof. You should not go around and post a list like this if you get all your info from forums or make it up yourself. Reading this is a waste of time.

  3. Christian

    this is well proven on dynos of cars that have had installed an h pipe and an x pipe on the same vehicle the same day. do your research. And as for you matt, do you ever think to actually understand what your reading? it might sound ridiculous because your not thinking about it with some common sense.
