Save yourself MAJOR headache.

The turbo studs on the FA turbo motors are notoriously difficult to deal with. If you're lucky enough to get the nuts off without drama originally, be sure to replace them with higher quality hardware. The factory nuts are locking nuts that are prone to damaging the low quality factory studs. With our J-Pipe, we include four custom CNC machined stainless steel studs along with matching nuts. By popular request, we're now offering this hardware kit for sale so that those running different J-Pipes can still benefit from the upgraded hardware.

GrimmSpeed J-Pipe Hardware Kit - 2015+ WRX

Just handling & looking at the components imparts confidence. I'm switching my factory J-pipe to aftermarket catless and want to take this opportunity to replace apparently less sturdy factory turbo bolts... especially since I expect to be revisiting that area in future. Cannot say it better... Save yourself MAJOR headache..!

Very high quality

I purchased this set after hearing the horror stories of broken studs etc. As it turned out, my original studs were in perfect condition, so I only used the nuts, and kept the studs for later use if needed.
