Twin Turbo Downpipe

The RP 3” downpipe for twin turbo equipped FD’s is a mainstay of the RX-7 reliability modifications. The elimination of the pre-catalyst significantly lowers under-hood temperatures and increases horsepower. This is a high ‘bang for the buck’ modification appropriate for any twin turbo FD. It is made in the U.S.A. and in-house designed for perfect fit and durability. ½” flanges and good hardware fitment are is the centerpiece of this design. The oxygen sensor has been relocated downstream about 6-inches and installed vertically. This improves sensor life and ease of service. Add a hardware and gasket kit and go. Gaskets are available individually. Note: Only for left hand drive vehicles!!! * One-piece 3” stainless steel mandrel tubing * Eliminates pre-catylist catalyst * Factory like fitment * ½ pro-fit flanges * O2 fitting included * Bolts to main cat or mid-pipe
