TiAL 004247 MV-S External Wastegate V-Band Stainless Steel - 38mm

The TiAL MV-S 38mm External Wastegate is a compact, high-performance boost control solution engineered for turbocharged applications. Redesigned from the ground up compared to its F38 predecessor, the MV-S stands only 3.7 inches in height, making it significantly easier to package in tight engine bays without sacrificing flow or reliability.

Key Features:

• V-Band inlet and outlet flanges for quick, leak-free installation and easy removal
• Three lower and two upper air ports provide flexible boost pressure reference and control plumbing configurations
• 38mm valve diameter delivers excellent exhaust flow capacity for high-horsepower builds
• Stainless steel construction for superior heat and corrosion resistance
• Compact low-profile design at only 3.7" tall — noticeably smaller than the F38 series
• Available with multiple spring pressure options for a wide range of boost targets
• Precision-machined internals for consistent, repeatable boost control

The TiAL MV-S is a favorite among professional tuners and enthusiasts alike for its ease of installation, robust build quality, and reliable boost control performance. The V-band clamp design eliminates the need for traditional bolt flanges, streamlining the installation process and reducing the risk of exhaust leaks. Compatible with TiAL's standard V-band wastegate flanges and widely supported by aftermarket turbo manifold fabricators.
