Revolution Exhaust Manifold Catalyzer Set 86 ZN6 / BRZ ZC6

Revolution all-stainless steel exhaust manifold and sports catalyzer center pipe set for early-model Toyota 86 (DBA-ZN6, 6MT) and Subaru BRZ (DBA-ZC6, 6MT). Pipe diameters: 42.7Φ–50Φ–54Φ, first catalyzer deleted. The manifold replaces the exhaust bottleneck, raising torque from 2500 RPM onward and smoothing the power dip around 4000 RPM. Peak power increase estimated at 12–15 HP with improved throttle response. High exhaust efficiency achieved while meeting current emission standards. Installation requires cutting the OEM second catalyzer section and reusing the OEM silencer; third-party rear mufflers that pass acceleration noise tests are also compatible. Included: stainless manifold body, sports catalyzer center pipe, O2 sensor extension harness, and original vehicle emission test report (gas report). Used condition from equipped vehicle; no accident or engine failure history. Normal operation with no exhaust leaks until removal. Used wear including rust, scratches, dirt, and discoloration present. Gaskets and mounting bolts not included and must be supplied by buyer.
