Design & Function
These flanges are purpose-built for custom exhaust manifold fabrication on the VR38DETT platform.
The oval-to-round transition design eliminates the need for complex port shaping, allowing fabricators to directly integrate 49mm piping into their manifold design. This not only improves workflow efficiency but also helps maintain consistent exhaust flow characteristics.
Designed with motorsport use in mind, the flanges provide the strength and precision required for high-boost and high-temperature environments.
Installation
Professional fabrication and welding are required.
These flanges are intended for experienced fabricators building custom exhaust manifolds. Proper jigging, alignment, and welding techniques are necessary to ensure optimal performance and durability.
Fitment
VR38DETT Engine
Nissan GT-R (R35)
