Product Information
A long tube header kit with 2 in stainless primary tubes merging into 3 in collectors, paired with catted stainless connection pipes that join the headers to the factory exhaust. Long tubes keep each cylinder's exhaust pulses apart for longer than the factory cast manifolds, which helps the engine breathe at higher rpm. The GREEN converters are rated for up to 750 wheel horsepower and suit forced induction, and no additional parts are needed.
