EPMAN 5-Bolt to 2.5″ V-Band Turbo Downpipe Adapter Flange with Gasket Kit for T25 T28 GT25 GT28 TD04 Turbine EPCGQ44Z

Product Overview:
Upgrade a custom turbo exhaust setup with EPMAN 5-Bolt to 2.5″ V-Band Conversion Adapter. This precision-engineered racing adapter bridges the gap between your turbine housing and your custom exhaust system. It converts a standard 5-bolt turbine downpipe discharge into a universal, high-efficiency 2.5-inch (63mm) V-band outlet, making future exhaust maintenance, installation, and removal quick and seamless.

Key Features:

• High-Flow Internal Design: The smooth, contoured internal transition minimizes exhaust backpressure. This maximizes exhaust gas flow velocity and helps your turbo spool faster.
• Leak-Free Sealing: The package includes a high-temperature composite crush gasket designed to match the 5-bolt flange profile perfectly, ensuring a permanent seal against harsh exhaust gases.
• Dual-Material Hybrid Construction:

  • Flange Side: Heavy-duty, laser-cut mild steel with a corrosion-resistant chrome finish to eliminate thermal warping at the turbo mating surface.
  • V-Band Pipe: Pure 304 stainless steel welded utilizing premium TIG techniques to guarantee long-lasting structural integrity under extreme heat.

• Streamlined Maintenance: Eliminates hard-to-reach bolts and brittle gaskets on your downpipe by replacing them with a clean, quick-release V-band clamp connection.

• Nissan Silvia / 240SX (S13, S14, S15): Perfect for SR20DET engine swaps upgrading to Garrett T25, T28, GT25, or GT28 turbochargers.
• Subaru Impreza WRX & STI (GC8, GDA, GDB): Excellent for custom TD04 or VF-series turbo upgrades looking to route into a custom 2.5″ V-band downpipe.
• Mazda MX-5 Miata (NA, NB): A staple component for custom side-mount or top-mount DIY turbo kits utilizing T25/T28 footprints.
• Nissan Skyline (R32, R33, R34): Used in twin-turbo RB26DETT setups or single-turbo conversions looking for high-flow exhaust clearance.
• Honda Civic / Integra (B-Series, D-Series, K-Series Turbo Conversions): Fits aftermarket log or ram-horn manifolds utilizing a GT28 style turbocharger.
• Audi / Volkswagen 1.8T (Golf GTI, Jetta, Audi A4): For big turbo upgrade (BTU) projects running a T25 or GT2871R exhaust housing.

• 1x 5-Bolt to 2.5″ V-Band Conversion Adapter Pipe
• 1x High-Temperature 5-Bolt Exhaust Gasket
