Exhaust System

Q: What does a resonator do on an exhaust system?

A resonator is a specific type of exhaust system part designed to eliminate specific sound frequencies, often referred to as "drone." It works with the muffler to create a smoother exhaust note. In many performance exhaust systems , the resonator is tuned to allow for an aggressive tone while keeping the cabin relatively quiet during highway cruising.

Q: How does an electric exhaust valve work?

An electric exhaust valve (often part of an exhaust valve kit ) allows you to bypass the muffler electronically. With an evil energy exhaust cutout , you can open the exhaust valves with a remote control to unleash maximum power and sound, or close them for quiet driving. This flexibility makes it one of the most popular exhaust system parts for enthusiasts.

Q: What are the benefits of performance exhaust systems?

Performance exhaust systems are designed to reduce backpressure and improve exhaust flow compared to stock systems. By using high-flow exhaust system parts like mandrel-bent pipes and performance mufflers, these systems can increase horsepower, torque, and fuel efficiency. Additionally, an evil energy exhaust setup provides a deeper, more aggressive exhaust note.

FAQs about Exhaust System

Have questions about upgrading your ride? Explore our guide on performance exhaust systems. We cover everything from the function of exhaust system parts and temperature management to choosing the right setup. Learn why enthusiasts trust Evil Energy for their modification needs.

An exhaust system is a series of piping and components used to guide reaction exhaust gases away from a controlled combustion inside an engine. A standard setup includes an exhaust manifold, catalytic converter, resonator, and muffler. In performance exhaust systems, these components are engineered to maximize flow, allowing the engine to breathe better and produce more power compared to restrictive stock systems.

A transparent illustration of a car highlighting the exhaust system components: Engine, Exhaust Manifold, Catalytic Converter, Resonator, Muffler, and Tailpipe. A text box explains that an exhaust system guides reaction exhaust gases away from combustion, and performance systems maximize flow for increased power.

The primary function of performance exhaust systems is to channel toxic exhaust gases away from the vehicle's cabin and release them safely into the atmosphere. Additionally, it quiets the loud noise of combustion (unless you use an evil energy exhaust cutout for sound) and cleans up emissions. High-quality exhaust system parts also help optimize backpressure to improve engine efficiency and fuel economy.

It shows optimized backpressure contributing to engine efficiency and fuel economy. A text box lists the primary functions as channeling toxic gases, quieting noise, cleaning emissions, and optimizing backpressure for efficiency.

Exhaust system parts can get extremely hot. The manifold can reach temperatures between 1,200°F and 1,600°F (650°C - 870°C), while mufflers and tips usually stay between 300°F and 500°F. Because of this intense heat, it is crucial to use high-quality components like our heat-resistant exhaust valves and durable evil energy exhaust clamps to prevent warping or failure.

A thermal diagram of an engine and exhaust system, showing the manifold reaching temperatures between 1,200°F - 1,600°F (650°C - 870°C) and the mufflers and tips ranging from 300°F - 500°F. A warning text states that exhaust system parts get extremely hot and recommends using high-quality heat-resistant components.

FAQs about Exhaust System

What is an exhaust vs muffler?

People often confuse the two, but there is a difference. The 'exhaust" refers to the entire system of piping and components (manifold, converter, pipes). The muffler is just one specific component within that system designed to reduce noise. At Evil Energy, you can buy complete performance exhaust systems or individual exhaust system parts like evil energy mufflers or an evil energy exhaust tip to upgrade just the look and sound.

What does a resonator do on an exhaust system?

A resonator is a specific type of exhaust system part designed to eliminate specific sound frequencies, often referred to as "drone." It works with the muffler to create a smoother exhaust note. In many performance exhaust systems, the resonator is tuned to allow for an aggressive tone while keeping the cabin relatively quiet during highway cruising.

How often should I replace my exhaust system?

Most stock systems last between 5 to 10 years, depending on driving conditions (salt and rust are major factors). However, enthusiasts often upgrade to performance exhaust systems sooner to gain power. You should inspect your exhaust system parts annually. If you notice rust on your exhaust pipe clamps or hear a change in tone, consider upgrading to stainless steel evil energy exhaust components for longer-lasting durability.

How does an electric exhaust valve work?

An electric exhaust valve (often part of an exhaust valve kit) allows you to bypass the muffler electronically. With an evil energy exhaust cutout, you can open the exhaust valves with a remote control to unleash maximum power and sound, or close them for quiet driving.

Better than Alum?

I debated getting an aluminum one but stuck with this. It’s been 2,000 miles and it’s bone dry. Very impressed so far.

Logan Peterson

Top quality kit

Much better than the standard rubber lines. PTFE is the only way to go if you don't want leaks down the road. Highly recommend.
