This package deal includes a set of ISR long tube headers (LTH) with a pair of our plug and play o2 extensions.You will NOT find a better deal anywhere else!!!

The ISR long tube headers are constructed with 304 brushed stainless steel and heavy duty flanges. Designed with a stepped primary, these headers are built to retain as much low and mid range torque as possible while allowing for good top end horsepower gains as well. Meanwhile,
The innovative High Ground Clearance, "HGC" design places the collector in a position to maximize ground clearance without sacrificing performance.

Each header features 2 o2 bungs placed downstream of the collector so that you can utilize your factory upstream and downstream o2 sensors. Our plug and play extensions for the upstream o2 sensors make this process seamless!!!

Which "Type" of o2 extension do you need?
To verify which type of extension your car needs, Simply pop your hood and look at the connector on your upstream o2 sensor. It will be located near the firewall area, and can be seen from either driver or passenger side of the car. If you are still unsure of which type you need, Please contact us prior to placing an order and we will be glad to further assist you. Extensions are for HR/VHR vehicles only.
