3.00 Inch Butterfly Kit

The 3.00 Inch Butterfly Kit from Quick Time Performance is an electric exhaust cut-out system designed for performance enthusiasts who demand versatile exhaust flow control. This butterfly valve solution allows drivers to electronically open or close exhaust flow, delivering immediate sound modulation and tuning capability without complex mechanical modifications. Ideal for street performance vehicles, this kit transforms exhaust character on demand—from subdued daily-drive acoustics to aggressive track-ready tone.

Engineered with brushed stainless construction, the 3.00 Inch Butterfly Kit delivers corrosion resistance and durability essential for long-term exhaust exposure. The electric actuation mechanism eliminates manual operation, enabling seamless transition between open and closed butterfly positions via simple electrical activation. A 3-inch diameter design accommodates mid-range to larger displacement applications, providing optimized flow balance while maintaining structural integrity under continuous operation and temperature cycling typical of performance driving environments.

This Quick Time Performance butterfly kit suits builders seeking refined exhaust tuning without permanent system changes. Installation integrates into standard exhaust piping at the 3-inch diameter point, making it compatible with both naturally aspirated and forced-induction platforms. The compact form factor—measuring 4.1 x 4.75 inches—fits within typical underbody clearances, while the lightweight 0.19 lb construction minimizes unsprung mass and supports overall vehicle dynamics. Perfect for custom exhaust builds, restomod projects, and performance tuning applications where controlled exhaust modulation enhances both function and driving experience.
