What does a crossover do for exhaust?

An X-Pipe or an exhaust H-Pipe are at the heart of a performance system and bolted in the center of the car. Also known as a crossover pipe, each system works by balancing the exhaust pulses from either side—or cylinder bank of a V-style engine. The result is a smooth exhaust flow and a more efficient engine.

Does H pipe add horsepower?

On a typical 400-horsepower street car, adding an X-pipe or an H-pipe to an existing dual exhaust system can add 7-12 hp. A smoother exhaust note and reduced interior resonance are added bonuses.

Where do the exhaust pipes cross over in a car?

They cope with this by having the two front cylinders exhaust straight into the muffler (via the heat exchangers which are also the headers), but the two rear cylinders have headers internally in the muffler. The header pipes actually cross over inside, so the left rear vents close to the right tail pipe and vice versa.

What to look for in an aftermarket exhaust system?

Muffler manufacturers configure these components in different ways to produce different exhaust tones. Ideally, an aftermarket muffler will provide a good performance exhaust tone without creating too much power-stealing backpressure. Crossover pipes are designed to balance the exhaust flow on a dual exhaust system.

How are crossover pipes used in a dual exhaust system?

Typically installed near the headers, crossover pipes reduce uneven exhaust flow from the two banks of engine cylinders by giving exhaust pulses an avenue to travel between the two sides of the dual exhaust system. This reduces backpressure by preventing an exhaust build-up on either side of the system.

How does tubing cross section affect exhaust system?

The area of a tubing cross section plays an important role in scavenging. “When you have an exhaust header that does not have a collector, that scavenging wave hits the end of the pipe and comes back there’s an important ratio that comes into affect. The greater the area ratio, the stronger that vacuum wave is.

Where can I buy an aftermarket exhaust tip?

Many aftermarket manufacturers will finish off their tailpipes with a chrome exhaust tip or polished exhaust tip. You can also buy exhaust tips separately in your choice of finishes or shapes.

When to use X pipe or H pipe exhaust?

If you’ve got a newer car, and you want to be sporting that feisty zing every time you hit the gas, the X-pipe exhaust option will help to sharpen your tone and your power output along with it.
