I am looking for a full exhaust for a 2000 civic EX. OEM in good shape, or a good aftermarket system. I need to replace the system on my car as the previous owner hacked together a nasty system. Welded all the way from the header to the muffler. I think I am going to need to replace the CAT and the two O2 sensors also.

I am in MN.

Thanks, Ivan!
