....because the original has a rust hole in it, which has rendered it noisy. New Honda OEM cats are </body>,100, and are discontinued for my car, to boot. I am therefore reduced to trolling the aftermarket, for which I have a healthy distrust. Enquiries at local garages turn up several brands. Good prices all, but no brands which inspire confidence. Being a twenty first-century kinda guy, I start looking online. Only to discover those very same sorry brands and not much else. However, I do discover a listing that, at least visually, looks suspiciously like my own OEM cat, here: <http://www.autopartswarehouse.com/search/?Ntt=hon1623&N=0&uts=true> Check it out. It's a dead-ringer for the OEM cat and lower heat shield. I had a nice online chat with an sales rep from Auto Parts Warehouse, the seller of that cat. A transcript is linked below. It's interesting reading. <http://www.tegger.com/hondafaq/misc/apw-hon1623-chat-transcript.txt> "John" is me. "Mari" is the APW rep. The upshot is that their photo is /highly/ misleading. Deliberately? You decide.
