Comments about Walker EPA Ultra Direct Fit Converter:

Failed emissions test on my 1999 Honda Accord EX. Code P0420. Researched and found this product. It was the direct fit. And wow...installed in 15 minutes. Note: I did have to go to the hardware store and purchace six new nuts and bolts...but that was a breeze to. Drove down to get restested for emmissions....PASSED !!!

Comments about Walker EPA Ultra Direct Fit Converter:

It would have been nice if both flange gaskets were in stock at my store, but only the header-side gasket was.

Regardless, its a good product, noted restored/increased performance. (My old CAT was completely clogged, so that is expected.)

      Comments about Walker EPA Ultra Direct Fit Converter:

      This converter is just as it says, it fits in perfectly. Keep in mind you will need 6 - 3/8" x 1 1/2" bolts with washers and lock nuts. The old converter has the bolts welded in. Also, don't forget to get new gaskets for each end. Important note, the bolt pattern is different on each end, so the gaskets are different on each end also. Don't order two gaskets the same or you'll be making an extra trip back to the store, (they do this because the converter is a one way. You cannot put it on backwards then).

          As others have written, the tough part is removing the old converter. Botling the new one on is easy once the old one is off. Remember to get new 3/8 x 1.5 in bolts and washers prior to starting work so you have all in hand once you cut the old bolts off and purchase the gaskets as well.

                • Q:

                  I have a 2002 Honda Accord Value Package 4 Cyl and i am going to purchase this Cat Converter to replace my OEM CC. I understand this does not come with gaskets or the mounting boults (6 total I think) if you damage the OEM bolts removing the CC. Does Advance sell the gaskets and mounting bolts individually or in a kit? If so could you tell me the part numbers? Thanks!

                    Happy to help you with your question E-Roc! We do carry the gaskets for this catalytic converter the front gasket will be Part No 31645 the rear gasket will be Part No 31383. We do not carry exact fit bolts for the exhaust but if you can bring one to your local store we can match some up with the selection of nuts and bolts we have.

                    Happy to help you Fernao de Magalhaes! Yes you would move the oxygen sensor from your old catalytic converter to your new catalytic converter. Before you remove the oxygen sensor I suggest Part No 16-PB http://shop.advanceautoparts.com/p/blaster-penetrating-catalyst-16-pb/7081146- to loosen and penetrate the rust on the oxygen sensor.
