EPMAN 2.5" 4-Bolt Turbo Discharge Downpipe Flange — 9mm CNC-Machined Cast Mild Steel EP-CGQ41Z

Product Overview:

Upgrade or custom-fabricate a vehicle's exhaust system with our Premium 2.5-Inch 4-Bolt Turbo Discharge Downpipe Flange. Engineered specifically for high-performance turbo configurations, this heavy-duty adapter bridges the gap between turbocharger's turbine housing and high-flow downpipe setup.

Crafted through precision casting and finished with advanced CNC-machining, it guarantees a perfectly true, flat mating surface. This meticulous manufacturing eliminates structural gaps, ensuring a leak-free seal that locks in maximum boost and exhaust velocity.

Key Features:

• CNC-Machined Sealing Surface: The flange face is precision milled to delete machine waves, offering an incredibly flat surface that prevents exhaust ticks and gasket failure.
• Premium Cast Mild Steel Construction: Offers exceptional thermal resilience against high exhaust gas temperatures while delivering superior weldability for seamless custom downpipe integration.
• Heavy-Duty 9mm Thickness: Designed at a robust 9mm (0.354") depth to withstand intense heat cycles and torque without warping or cracking under pressure.
• Universal 2.5" Inner Diameter: Features an optimized 63mm (2.5") central opening to match industry-standard 2.5" OD exhaust piping for maximum flow.
• Lightweight Geometry: Engineered with a contoured, low-profile outer shape to minimize unneeded engine bay weight without sacrificing structural rigidity.

Fitment & Application

This flange pattern is widely used across custom forced-induction builds and aftermarket performance systems. It serves as a direct fit or optimal fabrication piece for:

• Standard 4-Bolt T3, T4, T3/T4 hybrid, and GT35 series turbine discharge housings.
• Custom welding onto 2.50" OD exhaust tubing or mid-pipes.
• Custom turbocharger dump pipes, external wastegate discharge pipes, and downpipe transitions.

Package Includes

• 1x 4-Bolt to V-Band Flange Adapter

Note: Installation requires welding. Gaskets and mounting hardware are not included. Professional installation is highly recommended to achieve an optimal weld seal.
