TiAL 003843 MV-S External Wastegate V-Band - 38mm Stainless

The TiAL MV-S 38mm External Wastegate is a compact, high-performance boost control solution engineered for turbocharged applications demanding precise and reliable wastegate operation. Significantly more compact than its F38 predecessor, the MV-S stands just 3.7 inches in height, making it ideal for tight engine bay installations without sacrificing performance.

The MV-S features V-Band clamp flanges on both the inlet and outlet, eliminating the hassle of traditional bolted flanges and allowing for tool-friendly, leak-free installation and removal. The versatile port configuration — three lower air ports and two upper air ports — provides flexible pneumatic connection options to suit a wide range of boost control setups, whether using a single-port or dual-port actuator configuration.

Constructed from stainless steel with TiAL's signature precision manufacturing, the MV-S delivers consistent valve sealing and long-term durability under high exhaust heat and pressure cycles. The wastegate valve and seat are machined to tight tolerances for repeatable boost control and minimal boost creep.

Key Features:

• 38mm valve diameter for efficient exhaust gas bypass
• Compact 3.7" overall height — notably smaller than the F38 predecessor
• V-Band inlet and outlet flanges for easy, leak-free installation
• Three lower and two upper air ports for flexible boost control plumbing
• Stainless steel construction for heat and corrosion resistance
• Precision-machined valve and seat for consistent boost control
• Compatible with TiAL standard V-Band flange accessories and weld flanges

The TiAL MV-S is the go-to external wastegate for performance builders seeking a proven, compact design with professional-grade fitment. It is sold as a complete wastegate unit and is compatible with TiAL's range of replacement springs for adjustable boost pressure tuning.
