A'PEXi Exhaust Manifold with Catalyzer

Exhaust manifold and front pipe combo for the 2012-2021 Toyota 86, Scion FR-S, and Subaru BRZ designed by APEX’i. The APEX’i Exhaust Manifold with Super Catalyzer is a replacement header and front pipe for the ZN6/ZC6 chassis 86/BRZ designed to improve performance without raising exhaust volume. Exhaust volume is minimized through use of a high flow catalytic converter and muffler to reduce sound emissions while improving exhaust flow from the 4-2-1 equal length header. The new exhaust components retain the factory exhaust diameter, but with improved bends and routing exhaust gases are more easily released helping to eliminate the torque dip present in the midrange of the powerband. APEX’i has designed an exhaust combo for both the manual and automatic transmission.
