A'PEXi Exhaust Manifold with Catalyzer

Exhaust manifold for the 2022+ Toyota GR86 and Subaru BRZ designed by APEX’i. The APEX’i Exhaust Manifold and Super Catalyzer is a replacement header and front pipe for the second-generation 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. The new exhaust manifold, overpipe, and front pipe are only compatible with the manual transmission GR86/BRZ. The exhaust manifold is available with an optional heat shield to help reduce engine bay temperatures.
