EXHAUST SYSTEMS

It depends. For high-quality systems designed for optimal performance, like the ones offered by Integrated Engineering, prices can range from several hundred to a few thousand dollars or more.

The horsepower gain from installing a performance exhaust system can vary, but it's not uncommon to see increases of 5-20 horsepower, depending on the vehicle and the exhaust system's design.

Backpressure is a form of resistance against the flow of exhaust gasses out of the engine. Some level of backpressure is necessary for optimal engine performance. Too much, on the other hand, negatively affects performance.

Exhaust system kits are designed to minimize unnecessary levels of backpressure, thereby enhancing the engine's ability to “breathe” and ultimately resulting in performance gains.

No. But upgrading your stock exhaust parts with one of IE’s exhaust kits has several benefits, including:

• Exhaust performance and efficiency improvements
• Increased horsepower and torque
• A more aggressive exhaust note

• Cat-back exhaust systems replace the stock exhaust components from the catalytic converter to the exhaust tips, improving flow and sound without altering emissions.
• Axle-back exhaust systems replace parts from the rear axle to the exhaust tips, offering a more modest upgrade primarily affecting sound.
• Turbo-back exhaust systems (for turbocharged engines) replace everything from the turbo's outlet to the exhaust tips, offering the most significant performance improvements. Note: these types of exhaust systems often require additional tuning for both performance and emissions reasons.

The design of an aftermarket exhaust changes the look of your vehicle’s rear, making it sportier. But the design may also influence the exhaust note slightly too. For instance, larger tips can amplify the exhaust note, and different shapes can alter the timbre/tone.
