This is not the same old R53 Mini Cooper S header redone. This is our four into one collector with a scavenger spike to promote better airflow. Our header features 1.75″ primary tubing and a 3″ collector built from mild steel. In dyno testing our header was able to make 5-10WHP and almost 15ft-lbs Torque over other header types. It also has three O2 sensor bungs to make adding a wide band easy.
Now lets talk flex joint! This is what sets this header apart from the rest in longevity and strength. We have run many types of headers and flex joints on the track with multiple failures. This one will hold up to the punishment a race track hands out.
This is a race only header and replaces the Catalytic converter. NOT STREET LEGAL!
