These headers are custom built and designed by HSC for peak performance. They are a must have for an enthusiast looking to make significant power. They are constructed of stainless steel 1.75" primaries and 3" collectors. These are the same headers we used on our shop racecar.
The headers do not require coating. They are guaranteed for the life of the vehicle.
*The headers will fit on the FC RX7, but some clearance work on the lower firewall may be required.*
