The studs that connect the Midpipe to the J-pipe on model year 2015 and newer WRX cars break frequently, so we suggest installing fresh nuts and studs any time the J-pipe is separated from the rest of the exhaust, even if they have been done recently.
(There are also two bolts as this location, but those don't usually break.)
Kit includes two OEM Subaru studs and two matching nuts.
Fits all 2015+ Subaru WRX.
