I ordered this catalytic converter for my 2004 Civic as part of an exhaust design project that also includes changing the muffler, resonator, and manifold.The cat arrived packaged in plenty of protective material. There were gaskets and mounting bolts included. The build quality is pretty good. All of the seams are precisely welded, although there is some weld splatter in places that could have been removed. For something that lives where people won't see it, it looks nice. There are multiple locations for installing O2 sensors. I plugged two of them, as I only needed one downtream and the upstream on my manifold. You can see in my photo that the plugs screwed in easy enough.Although the product images include the dubious description of "Adequate catalyst material," the honeycomb looks great.I am still piecing together the exhaust piping, but this does seem to align with my new manifold. I will update this with additional pictures and information as it arrives.

I recently got this catalytic converter kit, and it was a good purchase.One of the things that's good about this kit is the compatibility. It covers multiple years.Another thing that's nice is the stainless steel body. The material is designed to help with rust.I also like that it comes with the gaskets and hardware. This makes the installation easier without needing to modify anything.Overall, this catalytic converter kit was a good value and purchase.
