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!


Are you wondering what the difference is between 304SS and 321SS? View the explanation in our tech section for the breakdown.


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


Welding an extension tube onto the turbocharger’s compressor outlet may be necessary for large frame T4 turbochargers.
