Cats work well, as advertised, unimpressed with fit
bought to replace my old cats which were rusted badly and making lots of rattling noise. I'm an experienced amateur mechanic and installed myself. Installation not a breeze. these match very closely the shape of the old cats, but not perfect. Driver side fits in but is millimeters from touching the transmission crossmember. passenger side fits but sits on transmission heat shield. performance of these, since installation, has been fine. no problems with engine performance.
