I returned the part as I did not need to replace at the time, but it looks like it would fit good if you can get the manifold nuts off. A small strong semi-flexible swivel on a 15mm air socket with a long extension will get you over the top of the converter to the top flange nut on the 2007 Chevy Implala.

The converter is nicely made, it welded in very well and was a good fit. It cleared my code for down steam 02 sensor. I can't say anything but good about it but need to see how long it lasts for a solid opinion. Magnaflow offers a heavy metal version that has better catalyst that may be a better choice for longevity. I did not know this before I bought and installed mine.

This product fit perfectly and sounds great. Even though it came with gaskets, I ordered some different ones as they were a better quality. it has a stainless steel construction so it should last a very long time. Shipping was also fast, I received it in about 8 days oversea. The product was packaged well and I received it with no damage. Advance Auto Parts is one of the few companies that will send to a APO address. I also liked where the oxygen sensor bung is placed on the side instead of on top of the pipe.

This is a good aftermarket cat that you will have to modify to fit your vehicle. This a universal cat that is determined to be an exact fit based on the engine you have in your vehicle and it's displacement. Exhaust flow rates will be different from a 4 to a 10 cylinder which means that all parts of an exhaust system have to be sized to meet a minimum flow rate to allow the exhaust gases to pass through without causing restrictions and hurting power and gas mileage.
