Exhaust Header for 2001-2005 Lexus IS300 3.0L 2JX-GEDOHC (Silver Polished)

The Exhaust Header for 2001-2005 Lexus IS300 3.0L 2JZ-GE DOHC (Silver Polished) by DynoVox is designed to enhance exhaust flow, boost horsepower, and improve engine efficiency. Crafted from high-quality stainless steel with a silver-polished finish, this performance header reduces backpressure and maximizes airflow for better throttle response. Precision-engineered for a direct fit, it ensures durability and long-lasting performance. Upgrade your Lexus IS300 with DynoVox’s premium exhaust header for enhanced power and sound. Ideal for performance enthusiasts looking for increased efficiency and a race-inspired exhaust tone. Perfect for off-road and competition use.

Advantages of DynoVox Headers:

  • Improved Exhaust Flow: Each cylinder has its separate pipe in the exhaust headers, allowing for smoother and more efficient exhaust flow. This reduces back pressure on the engine, enhancing overall performance.
  • Increased Horsepower and Torque: With reduced backpressure, the engine can "breathe" better, leading to increased horsepower and torque output, especially at higher RPMs.
    Enhanced Sound: Exhaust headers can alter the exhaust note, producing a deeper and more aggressive sound than stock exhaust manifolds.
  • Replacing Exhaust Manifolds: Upon installation, headers replace traditional exhaust manifolds. Instead of a single-piece manifold, headers have separate pipes for each cylinder, which then merge into a collector that directs the exhaust gases into the rest of the exhaust system.

Differences Between Headers and Manifolds？

Exhaust manifolds are factory-installed components found on almost all vehicles, while headers are aftermarket upgrades. However, there are exceptions as some high-performance cars come from the factory with headers.
Manifolds are much cheaper compared to headers, as headers require careful development specific to the engine they are paired with, and they also use higher-performance materials.
Manufacturers design exhaust manifolds to provide a balance of performance, fuel economy, and efficiency, while headers are primarily designed to offer optimal performance.
Headers often reduce exhaust backpressure, resulting in improved performance at high RPMs and the associated noise, while exhaust manifolds retain some backpressure to ensure driving performance across a wider range of RPMs and reduce noise.

Do headers make your exhaust sound better?
With exhaust headers, your exhaust notes will be smoother, more defined and far more aggressive.
Are stock headers better than aftermarket?
An aftermarket stock header deals with the exhaust gasses in a much more efficient way, which improves the overall performance of your engine. Performance headers are more concerned with increasing performance rather than reducing the noise from the engine.
Will headers increase gas mileage?
To really maximize fuel economy, performance headers are manufactured to a shape and size that improves engine “breathing.
