LEXUS IS500 V8 5.0L F1 sound Valved Racing Exhaust system | GWAPOTech JAPAN
The muffler for the Lexus IS500 2022+ 5.0L V8 consists of:
Exhaust manifold
Front and center muffler
Rear muffler
*Currently, the exhaust manifold is only compatible with left-hand drive models, but development for right-hand drive models is underway in the country.
First, let’s take a look at the exhaust manifold on the engine side!
The stock exhaust manifold has tubes of varying lengths and features a large catalytic converter. Naturally, the design disregards sound and exhaust efficiency, so there is significant room for improvement in this area.
At our company, we have designed the tubes extending from the flange to be maximally long, and we also provide the option to add sports catalytic converters ranging from 100-300 cells. Notably, each tube is of equal length, contributing to high-frequency sound, preventing sound distortion, and extracting essential elements for racing sound design.
Next, we will examine the front center section.
The original front pipe and center pipe have a very large catalytic converter, which naturally limits sound volume and results in a muffled deep bass sound.
Our front pipe is designed to produce a high-frequency sound while optimizing exhaust efficiency. In addition to straight pipes, we also offer resonators and optional sports catalysts with 200 cells for an additional fee.
Additionally, for the cross-section where the exhaust from both banks intersects, we can provide not only an X-pipe but also a specially designed merging section for customers who desire higher sound frequencies.
Now, let's introduce the rear muffler.
The original rear muffler has a large silencer, which decreases exhaust efficiency and cannot avoid producing a muffled deep bass sound.
Our center muffler and rear muffler are designed not only for weight reduction but also to meticulously balance piping design, punching, and glass wool.
To emphasize the ON/OFF of the valve, we adopt a larger silencer design, ensuring that in silent mode, the volume level matches that of the original silent mode, allowing for a gentlemanly specification that can be driven comfortably at night or in residential areas.
When the valve is open, it allows the engine to perform at its full potential while producing a racing sound, making it a fun sound-tuning item for everyday driving experiences.
There are also plenty of options for muffler tips, so you can select a specification that perfectly matches the image of your vehicle.
