Are you searching for a high performing exhaust manifold for your 2JZ-GTE that doesn’t break the bank? Look no further, the Gen II R-Spec is here! BP Autosports is known for our innovative, power-producing exhaust manifolds, and the Gen II R-Spec is no exception.

These manifolds take the design principles implemented in our billet collector Gen-R line and bring them to you in a budget-friendly, fully-fabricated package. What does this mean for you? Exemplary performance without the sticker shock; it’s a win-win!

All Gen II R-Spec manifolds feature the following:

  • 1.25" schedule pipe primaries and 2" schedule pipe secondaries for optimal strength, flow, exhaust gas velocity, spooling characteristics, and power

  • 304SS or lightweight, exotic 321SS construction

  • Hand fabricated and internally welded primary and secondary merge collectors, designed to provide unparalleled exhaust flow, collector efficiency, and boost control characteristics

  • M10x1.5 tapped turbine flange

  • Professionally TIG welded and back purged with special attention paid to weld aesthetics; our manifolds not only perform well, but look great too! 

These manifolds are available with either forward or rearward wastegate positioning, referring to the placement of the forward wastegate.
