The PERRIN Brackets for HELLA Horns are designed in three variants allowing for a perfect fit on your specific model of WRX/STI. Being tailored for specific models makes for better fitment than universal brackets. The end Plates are slotted so you can adjust the horns up or down for a custom look or clearance. These brackets are built to last, each one is made from thick precision laser cut CNC-formed 304 stainless steel, and powder coated black. Purchase just the bracket or the bracket plus a pair of genuine Hella Supertone horns.
