BRZ, FRS & 86 FA20 & FA24 Unequal Length Ceramic Coated Header

Product Description

AVOTurboworld's BRZ/FRS/86GR Unequal Ceramic Coated Exhaust Manifold for NA performance upgrades.

In our initial testing with the Subaru BRZ 2022 FA24 fitted with the AVO 2.5-inch Front Pipe and Cat Back Exhaust system we gained 8hp and 10fp torque.

By adding our bolt on replacement header with our 2.5-inch crossover pipe we gained an additional 10hp and 10fp torque.

From the standard vehicle making 223hp and 190fp torque.  By installing the AVO Unequal Ceramic Coated Exhaust Manifold combined with the AVO 2.5inch Crossover Pipe / Front Pipe with Cat / Cat Back Exhaust System we gained 18hp and 20fp torque over the stock figures without an ECU tune.
