How does this exhaust cutout valve operate?

This valve is designed to be normally closed, meaning your exhaust will flow through your muffler as usual. When your engine builds boost, the pressure will automatically open the valve, bypassing the muffler for a louder exhaust sound.

What material is this valve made from?

The valve is constructed from 304 stainless steel, which is known for its strength and resistance to corrosion, making it suitable for the harsh exhaust environment.

About this part

Product Details

Stainless Bros is known for making well-built exhaust components. This 3.0-inch exhaust cutout valve is designed to give you more control over your vehicle's exhaust sound and flow. It operates normally closed, meaning your exhaust stays quiet and routed through the muffler by default. When your engine builds boost, the valve automatically opens, bypassing the muffler for a louder, more aggressive exhaust note.

Constructed from 304 stainless steel, this valve is built to resist corrosion and withstand the heat and pressure of your exhaust system. The 3.0-inch diameter makes it suitable for a wide range of performance exhaust applications. Installation involves cutting into your existing exhaust system and welding this valve in place. Please note that this part is not CARB approved and cannot be shipped to California.
