The Lexus IS300 2001 is a classic performance and luxury car. Its reliable inline 6 engine makes it a much-loved car for auto enthusiasts. The car is synonymous with a smooth-handling car having a luxurious interior. However, the factory tune and styling are only the beginning for many owners. Better performance and an intoxicating exhaust note are what they are looking for. One of the most impactful upgrades you can make to your 2001 Lexus is300 headers is the installation of the exhaust headers, and it is time to hit the install.
If you are not sure where to even start if you want to increase the IS300’s sound and performance, this guide is for you. Exhaust headers are what we will explain. You will know their benefits and choose the best one that suits your ride.
Understanding Exhaust Headers
Exhaust headers are no longer factory exhaust manifolds. Their purpose is to collect exhaust gases from your engine and send them to the exhaust system. Stock manifolds are designed to be very restrictive. Each cylinder has its tube used to direct gases to the headers. The motor inhales without a bottleneck, reducing back pressure. The combustion will be more efficient because it is improving the airflow. It also takes the mud off your car, which makes the exhaust note cleaner for a cleaner sound.
Benefits of Upgrading to Headers
- More Power: Pullers of extra horsepower and torque, mostly at higher RPMs.
- Better Exhaust Flow: Fewer restrictions allow your engine to kick out of its lungs a little more efficiently.
- Signature Sound: It won’t sound very different, but you will have a deeper, sportier tone that you can not get with a stock setup.
- Enhanced Aesthetics: Under the hood, headers are a great idea with polished or ceramic-coated options.
Headers vs. Stock Manifolds
You can also find stock exhaust manifolds designed to cut costs and meet emissions standards at the expense of all that performance. At the other extreme, headers are a niche product geared more toward enthusiasts, and performance is the name of the game.
Here is what you stand to gain:
Boosted Horsepower and Torque
It’s a huge performance gain from upgrading to high-flow heads. This upgrade brings a boost in power that your car can really use, regardless of whether you have one or the other.
Improved Exhaust Flow
The headers provide negative back pressures in the exhaust system. They eliminate bottlenecks. By lowering the throttle tip angle, they increase efficiency and smoothness.
A Sportier Soundtrack
Do you enjoy hearing a refined, aggressive growl? Tuned headers to unique lengths or equal lengths give your IS300 an unmistakably sporty tone.
