The TurboXS front pipe hardware kit for 2015–2021 Subaru WRX replaces the four turbine-side studs that commonly seize or strip and includes stainless steel studs plus zinc-coated nuts and bolts for durability. Supplied to support front pipe replacement, the kit provides the listed studs and fasteners so installers can secure a higher-flow front pipe without risking damaged original studs.
