Material: Stainless Steel construction (SS variant).
Function / Purpose: Acts as an optional header / exhaust collector (4-into-1 design) to be used in conjunction with an Akrapovič slip-on / muffler. It allows upgrading the front header portion without replacing the entire exhaust system.
Performance / Benefits:
• Improves exhaust flow and reduces weight (as the stock catalytic or factory header is often heavier).
• To maintain proper engine performance and avoid check engine faults, ECU remapping or tuning is often recommended when installing optional headers.
