BMW E90/E92/E93 M3 Valved F1 sound Exhaust system | GWAPOTech JAPAN
The exhaust for the BMW E46 M3 consists of:
Exhaust Manifold
Center Exhaust
Rear Exhaust
Notably, the stock exhaust manifold is equal-length and does not have a silencer, so we have not developed an exhaust manifold.
Below is an image of the stock equal-length exhaust manifold. The angle of the merge collector where the four tubes combine into one, the length of the manifold tubes, and the consistency of the pipe's smooth shape make it a perfect finish.
Now, as a sound tuning replacement point, let us first introduce the center exhaust.
The stock center pipe has four large silencers, and there is a catalytic converter on the front side, which naturally reduces the sound volume.
We use a straight center exhaust that removes the catalytic converter. This is highly effective for increasing volume, reducing weight, and enhancing horsepower tuning.
Resonators can be added according to your preference.
Notably, our recently developed high-pitched center exhaust adopts a unique merging style that replaces the X-pipe design at the crossover point where the left and right exhausts intersect with a single I-pipe to achieve a high-pitched sound and prevent sound breakage.
The standard design center exhaust aims for a moderate sports sound, whereas this high-pitched design results in an explosive increase in high RPM sound range, creating an F1 sound package.
Next, we introduce the indispensable sound tuning part, the rear exhaust.
The stock rear exhaust, like the center exhaust, has a large silencer, which restricts exhaust efficiency.
Our variable rear exhaust emphasizes the distinction of the valve's ON/OFF. In silent mode, it is designed to have the same volume level as the stock silent mode, making it a gentleman's specification that can be driven comfortably even at night or in residential areas.
When the valve is opened, the layout ensures the tubes are completely independent from the silencer, maximizing the potential of the NA engine and producing a racing sound.
This becomes a sound tuning item that enhances the everyday driving experience.
We also offer a variety of rear exhaust tip options, allowing you to choose the best design based on your vehicle's image.
