A Mustang H-pipe allows your exhaust system to breathe more effectively and improves both the performance and sound of your ride. With a small pipe connecting the two pipes coming from the exhaust manifold, an "H-pipe" creates the deep muscle car exhaust note and low-end torque that Mustangs are known for.

While H-pipes do limit the amount of backpressure in your exhaust system, unlike X-pipes and Y-pipes, they use some of that backpressure to create extra low-end torque. This gives you that extra "kick" that many cars equipped with H-pipes have when stepping on the gas. Plus, you get a deep, throaty exhaust note that can't be matched by other mid-pipes.
