One factor to consider when purchasing an aftermarket exhaust system is material. Most factory exhaust systems are made from lighter steel, resulting in faster deterioration over time. Installing a high-quality exhaust system made from aluminized or stainless steel will offer your system more longevity.

Pipe shapes are another feature to factor into your purchase decision. There are a couple different bends and sizes to examine:

  • Crush Bend - Pipes have a crinkled area which lessens the diameter and slows the gases.
  • Mandrel Bend - Pipes are smooth and one consistent diameter. Less resistance means more productive airflow.

 

Most cars and trucks benefit from larger pipes; however, if you opt for a pipe that’s too big, you can actually hinder your vehicle's performance. (One exception to this rule: If you’re adding a turbocharger or supercharger, you'll want to go significantly larger than your stock exhaust.)

Here are the main reasons to get a new exhaust system:

  • Remove restrictions. When your exhaust pipe is bent properly, exhaust flows freely away from your engine, giving it more power and torque.
  • Amplify sound. One of the quickest and most noticeable effects of a new exhaust system is the sound. That distinct rumble will be recognized anywhere you go.
  • Increase diameter. Pipes larger in diameter allow for better air flow, increasing performance and efficiency.
  • Improve looks. Car enthusiasts will see and hear your high-quality exhaust system right away.

 

Before you install a new exhaust system into your vehicle, understand they aren’t right for all cars. If a vehicle has a smaller engine, installing a new exhaust system will only make the car louder, not increase the power. High-quality exhaust systems are best for cars with larger engines, such as a V8 or turbocharged engine.

Be sure to do your research to find out if your vehicle is a good match for an exhaust system.
