Center an Image using text align center

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.
