TiAL Sport MVR 003409 44mm External Wastegate 14.5 PSI w/Clamps Purple

Vehicle Fitment

• Universal - fits any turbocharged application using a 44mm external wastegate with a compatible v-band or flange connection

Fitment Notes

• External wastegate - requires fabrication or a compatible manifold/downpipe with the correct wastegate flange to install; this is not a bolt-in replacement for a factory internal wastegate
• Compatible with other TiAL 44mm wastegates and select competitor wastegates (e.g., Precision, Turbosmart) using the same MVR-style flange - confirm your manifold or exhaust housing uses a matching flange before ordering
• Purple color and 14.5 PSI spring rate are specific to this SKU - TiAL offers this same wastegate in other colors and spring pressures under different part numbers
• Not CARB legal - check state and local emissions/modification regulations before installing on a vehicle driven on public roads

Features

• 44mm valve diameter sized for mid-to-high horsepower turbocharged applications
• 14.5 PSI spring included, setting the base wastegate opening pressure for this configuration
• Comes complete with V-band clamps for inlet and outlet connections
• Nickel-chromium-iron alloy construction handles sustained high exhaust gas temperatures
• In-house designed, engineered, and manufactured hardware - TiAL does not use off-the-shelf clamps or flanges, ensuring precise fitment tolerances
• Decades of proven motorsport use across a wide range of racing disciplines
• Suitable for street performance and dedicated race applications

Product Description

Once a turbo build exceeds what a factory internal wastegate can regulate, boost control becomes inconsistent - overshoot, creep, and poor spool characteristics all trace back to a wastegate that can't flow or respond fast enough. TiAL's MVR 44mm external wastegate addresses this with a purpose-built design sized for serious horsepower applications, using a nickel-chromium-iron alloy construction that holds up to sustained high exhaust gas temperatures without the fatigue or warping that lesser materials experience.

This particular unit ships with a 14.5 PSI spring installed, setting the wastegate's base opening pressure - swappable later with TiAL's other spring options if your boost target changes. TiAL manufactures all mounting hardware in-house rather than using generic off-the-shelf clamps and flanges, which is why the included V-band clamps are engineered specifically to this wastegate's tolerances rather than sourced as a generic fit.

This wastegate suits turbo builds - whether a custom manifold, aftermarket header, or downpipe - designed around a 44mm external wastegate flange. Since this is a fabrication-oriented component rather than a bolt-in part, confirm your manifold or exhaust system is built (or being built) to accept this wastegate before ordering, and factor in the additional plumbing (vacuum/boost reference lines) any external wastegate installation requires.
