Both the dismantle and installation process of the header is accessed via underneath of the vehicle, where more space is permitted.

Please note that, there are only 5 washer-ed nuts and studs on the original engine block and it is perfectly fine with that, even though the SuperCircuit Header flange is designed to take more nuts (see below).

Remember to reuse the metal gasket on the original stock header and reapply exhaust cement onto both sides of it before installing.
