Brand new Prosport headers and uppipe for Subaru 02-14 WRX and 04-21 STI. Headers and up pipe are made from T304 stainless steel, gaskets and hardware are included aswell. These are high quality headers that I purchase in bulk and then my shop does high temp cerakote and titanium header wrap! Greatly reduce engine bay temps and increase turbo spool time. Users typically see HP gain of 20Hp and 18TQ just from swapping to these headers. The Unequal length design keeps that’s iconic Subaru rumble and offers easy install and OEM fitment.
