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.

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

Headers, Tight Tubes Street Rod, Block Hugger, Steel, Black Ceramic Coated, Dodge, Plymouth, Pair

Hedman Tight Tubes offer the lowest profile header collector available. Chosen by professional car builders and seasoned gearheads, with Hedman's innovative 4-into-1 Tight Tubes the collector tucks the header tubes and hook-ups against the engine block for more component clearance than ordinary street rod headers. And, the larger volume collector design provides exhaust flow that surpasses standard block hugging designs. Available in mild steel with 16-gauge header tubes uncoated and coated. The HTC silver and Black Maxx ceramic-metallic coatings offer superior heat insulation and anti-corrosion properties to protect your "Hedder" investment and retain more heat inside the header tubes for increased exhaust velocity and improved scavenging. For tight engine compartments, choose Hedman Tight Tubes—the headers that go where ordinary headers won't.
