Classification and Introduction of GRWA Exhaust Valves

In the automotive parts industry, exhaust valves have always been a focal point for car owners due to their crucial role in regulating vehicle performance and sound. GRWA, a leading figure in the automotive parts sector, is dedicated to providing high-quality exhaust valve products that cater to the diverse needs of car owners in terms of vehicle performance and sound. Today, let's delve deeper into GRWA exhaust valves.

1. Functions of GRWA Exhaust Valves

The primary function of GRWA exhaust valves is to control the sound of the muffler. With the modified exhaust valve, car owners can open it when needed to enjoy the roaring sound waves or the thunderous noise of their vehicles, adding a sense of passion and dynamism to their driving experience. When not needed, car owners can easily close the exhaust valve to restore the vehicle's original sound, ensuring both comfort for daily driving and the ability to unleash inner wildness when desired.

2. Classification of GRWA Exhaust Valves

The classification of GRWA exhaust valves is mainly based on their working principles and structural characteristics. Depending on the direction of the pull-pack movement, GRWA exhaust valves can be divided into positive pressure exhaust valves and negative pressure exhaust valves.

1) Positive Pressure Exhaust Valves

Positive pressure exhaust valves have relatively shorter pull rods. Their working principle involves using the turbocharger to blow air, causing the pull rod to move from inside to outside. Positive pressure exhaust valves are suitable for vehicles equipped with turbochargers, but the specific use depends on the engine configuration.

2) Negative Pressure Exhaust Valves

Negative pressure exhaust valves have relatively longer pull rods. Their working principle involves sucking air from the vehicle's vacuum tube, causing the pull rod to move from outside to inside. Negative pressure exhaust valves are the choice of most customers, but it is advisable to contact GRWA customer service before purchasing to confirm the requirements for positive/negative pressure and normally open/normally closed configurations.

Furthermore, based on power types, GRWA exhaust valves can also be classified into vacuum exhaust valves and electric exhaust valves. Vacuum exhaust valves come in four styles: normally open positive pressure, normally closed positive pressure, normally open negative pressure, and normally closed negative pressure, catering to car owners' diverse needs for sound and performance. Electric exhaust valves, with their intelligence and efficiency, have won the favor of an increasing number of car owners.

3. Conventional Sizes and Featured Products of GRWA Exhaust Valves

GRWA exhaust valves offer a variety of conventional sizes for car owners to choose from, including:

GRWA has also introduced titanium alloy valves, which provide car owners with a more reliable option due to their high strength and corrosion resistance. Currently, the conventional sizes of titanium alloy exhaust valves are 63mm and 76mm.

To further optimize the smoothness and efficiency of the exhaust system and meet the modification needs of specific vehicles, GRWA has also specially introduced exhaust valves with T-pipes/Y-pipes.

For BMW owners, GRWA has launched a new BMW exhaust valve. This exhaust valve is installed in conjunction with the original black component on the right side. All that is needed is to ensure that the three screw holes on the exhaust valve align with the three screw holes on the black component. Additionally, although this exhaust valve does not distinguish between normally open and normally closed, installation does require differentiation based on the position of the spring.

GRWA brand exhaust valves have won the love and trust of an increasing number of car owners with their diverse classifications, excellent performance, and reliable quality. Whether you are a race car driver pursuing speed and passion or a car owner focusing on daily driving comfort, GRWA can provide you with the most suitable exhaust valve product.
