    Comments about Walker Universal Catalytic Converter:

    I went with Advanced Auto (vs. AutoZone) for the Online order which included $25.credit offer on my over $200. purchase. Lost that when I had to exchange product at store and NO WAY to use my Paypal in store vs.online. Should be able to do exchanges on same creditcard. Followed input info to order online but still got wrong product. Wasted mechanic's time doing exchange. Messed up my day twice. I do have to say the store clerk was very helpful & very fast with multiple crazy customers.

        Easy to install once you know the proper direction. If you look into the Cat, you will see 499A on one screen and 499 on the other. 499A is the inlet, but it does not indicate that anywhere. Thanks to an online Customer Service Rep who gave me the answer, I was able to install this properly. It would be much easier if Walker just put an arrow on the sheet metal!!!

        Thus is a good replacement, but you have to have extensive Experience to fabricate and install this unit... they make a 2nd unit that is cheaper then the OEM,but is a direct fit, i would knowing what i no now go that route.

            True it was not an exact fit. However, The muffler shop cut the old one out, made and fitted this new one with whatever bend and cut of pipe to make the new cat fit - without leaking for [$] ...In the Advance Auto Parts network, - at least in the region we are in - the direct fit model was some [$] pricing without installation - and proved to not be in stock anywhere. [$] installed was a good price for me.

            Best Uses

              Comments about Walker Universal Catalytic Converter:

              I ordered the one w/o flanges for my daughters 2003 Ford Focus LX SOHC 2.0L that requires welding. I figured I could save $120 by welding it myself with my mig welder. It's not an exact fit though. On this product the in port and out port are 180 degree out, like a regular muffler. The OEM product on the out board side is actually at a 45 degree angle. I could have still used it, but it required some jimmy rigging and will hang a little lower under the car. So check the fit before going through all the trouble to remove. I'm going to just spend the extra $120 to get with flanges for an exact fit.

                    This converter was welded for me at a local [...] for $80. No problem at all. Worked the first minute, whereas the Eastern catalytic piece that I had install 1 year ago -- never worked at all (the engine light has been on the entire year). Very pleased.

                        This product is listed as an exact fit for my 2003 Ford Windstar van; however, the actual part is a "y" pipe with two banks. If one of the two banks are bad, can I replace it with this part? Or, if both banks are bad, can I replace each of them with one of these? This option is still quite a bit cheaper than purchasing a "y" connector with two banks for a vehicle with 270K miles. Any advice other than those options would be greatly appreciated!
