Note for Australian and European Markets

Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components, pedals, shifters, linkages, wing mirrors, instrument clusters, panhard rods/traction bars, drag links, brake boosters, brake or clutch lines, accelerator cables, heater cores, some master cylinders and adjacent parts can vary between LHD and RHD configurations. In some models compenents such as windscreen wiper arms, motors and linkages could differ in their size and orientation. Items such as floor mats & dash mats may have differences in their structure around the front row (or padding in different locations). In many cases items are identical depending on the design of the vehicle and part, but may have differing mounts, lengths or bolt patterns. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.

For the price, no other part can give you the horsepower and fuel economy improvements of Hedman headers. They make Hedman Street headers so well that they guarantee them to be free from defects--including cracks in the tubes and welds--for the life of the headers. Hedman Street headers are available uncoated or in Black Maxx or their polished HTC thermal ceramic coated finishes and, as an added bonus, they also come with all necessary gaskets and mounting hardware. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts, and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom-altered parts, then it is the installer's responsibility to verify fitment.

Special warning regarding Hedman painted headers only. The paint on these headers is not designed as a final finish; it is designed to protect the headers after the manufacturing process and during shipping. This paint will not withstand the high heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high heat paint or coating designed for use on headers be applied.
