Product seems to be well made and supplied with good gaskets/o-rings/hose, install went pretty smooth, was already in there fixing the STC Coupling and replacing oil cooler. Bolts included with the Up-pipe seemed too small for my liking so I re-used the old ones. Otherwise up-pipe is of good quality and fit nicely. J-tube looks well made and is the single piece design (i.e. won't leak). Would definitely buy again.
