Overview

The Nismo 14004-06U01 is a genuine Nissan N1 exhaust manifold. This part is designed for all RB26DETT engines.
Show original supplier description
The Nismo N1 exhaust manifold provides an efficient upgrade for RB26DETT engines, featuring a "big port" design optimized for improved exhaust gas flow. As a genuine OEM component, it ensures factory-grade fitment and durability for enthusiasts looking to maintain or enhance engine performance. This manifold is specifically compatible with the RB26DETT engine series found in Nissan Skyline GT-R models (R32, R33, and R34). Please note that these manifolds are sold individually; users requiring a full set should plan accordingly. Compatibility with other Nissan GT-R models, such as the 2009-2020 3.8L V6 variants, is listed in certain official parts catalogs, though the part is primarily associated with the RB-series heritage. Buyers should be aware that while this is a direct replacement part, professional installation is recommended given the complexity of the RB26DETT turbo assembly.
