Killer B's Holy Header was designed using CAD software to determine the most efficient design possible. The header features short equal length primary runners that merge into a single secondary runner to decrease header volume. This makes it so exhaust gas builds quickly for improved throttle response, but moves consistently enough to let the motor breath in the top end of the rev range. This header also includes a v band uppipe to complete the pre-turbo exhaust setup. The Holy Header is constructed of TIG welded 321 stainless steel for maximum strength and durability.
