Spectral Performance proudly carries a great selection of automotive performance products brought to you by the metal masters at Killer B Motorsport.

This is the Killer B Motorsport Holy Header Max VE. The Holy Header from Killer B has established itself as one of the more coveted aftermarket header options on the market due to the performance and build quality. It is pure metal fabricated art designed to provide your engine with unobstructed exhaust flow to produce more horsepower, more torque, all while generating an aggressive exhaust note. The factory exhaust manifold is extremely heavy and restrictive by design and leaves much room for improvement. The Holy Header Max VE has been developed using state-of-the-art CAD software along with simulations and testing to determine high-power and RPM efficiency.
