TiAL 003980 MV-S 38mm External Wastegate with V-Band Flanges

The TiAL MV-S 38mm External Wastegate is a compact, high-performance boost control solution designed for turbocharged applications. 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 where space is at a premium.

Key Features:

• V-Band upper and lower flanges for fast, leak-free, and pain-free installation and removal
• 38mm valve diameter for efficient exhaust gas bypass and precise boost pressure regulation
• Three lower air ports and two upper air ports for flexible pneumatic boost control plumbing configurations
• Compact design at only 3.7" in height — noticeably smaller than the F38 predecessor
• Stainless steel valve and internals for durability under high exhaust temperatures
• Available with multiple spring pressure options to suit a wide range of boost targets
• Precision-machined aluminum body for lightweight strength

The TiAL MV-S wastegate is a trusted choice among performance tuners and motorsport builders for its reliable boost control, straightforward serviceability, and proven construction quality. The V-Band clamp interface on both the inlet and outlet flanges eliminates the need for traditional bolt-flange setups, significantly reducing installation time and improving sealing integrity.
