"but, if you're buying it for a 93 escort lx, it won't. The part number matched, and it was identical to the picture on the website, but it just didn't fit. if you order it and it doesn't fit, just send it back because once you cut it, its too late. don't cut it and weld it to make it fit unless you enjoy anger frustration, and wasting time. "But I'll make it fit!" says the dumb redneck. I made it fit eventually, but it wasn't easy nor was it worth the time. once it was customized to fit, the o2 sensor was pressed against an a/c line. I ended up breaking the sensor and having to buy a new one ($47), cut the fitting off, and weld it on in a different spot. a series of bad decisions on my part. eventually it fit, but man, what a pain! The local "Irish" parts store in my town had the same part for the same price that I could've bought and returned much more easily. I don't recommend buying this or any aftermarket cat online because you never know if it will fit correctly."

"Plug and play only change 5 screws and O2 sensor and you are ready to go. Passes all chilean stringent emission tests.
Con: There is no protection for the O2 sensor like the original Catalytic converter so its exposed to damages. Modifications under car must be made to minimize vibration sounds."
