Product Details

CalCat™ Catalytic Converter and Pipe Assembly by Walker®. Walker offers complete coverage: direct-fit mufflers, converters, pipes, resonators and accessories. Walker is an OE supplier to many major nameplate vehicle manufacturers. Trust Walker, an industry leader, for the finest emission control technologies for import and domestic vehicles. May require modifications to complete installation, professional installation recommended.

For safety and legal reasons, a faulty catalytic converter can’t be ignored. By transforming toxic gases into less harmful compounds, the catalytic converter does the important job of limiting emissions. If you are looking for a quality universal fit catalytic converter, you can rely on Walker as it has vast experience in manufacturing emission control devices. Walker produced crankcase emissions control equipment in the early 1960s and, working closely with the Environmental Protection Agency (EPA), produced the 1st universal aftermarket catalytic converter in 1978.

Unlike the direct fit catalytic converters that come ready to install and are designed to fit your specific make and model with no alterations, the universal fit catalytic converters may require cutting, welding, and other modifications to complete installation.

2006 Altima 2.5 Cat-Convert & Pipe Ass'y
Product looks great! Very easy to install, just had to buy the (2) rear nuts & bolts that mount it to the resonator, which was no problem. I would recommend this product to all. Very happy!

Good Cat.
The cat I purchased for my Subaru Outback functioned as it should. I passed the smog inspection. It did fit well enough. There were some issues with the heat shields from the stock unit not fitting over the large tabs of excess metal shown in the photo. There did however, appear to be some integral shields on the rear cat and a "double wall" pipe section on the unit that I suppose suffice. I was able to fit the main shields on to the first cat so it seems fine. I recommend that the entire Y-pipe and cat assembly be dropped together and swapped out on the bench so you would need new gaskets for the head and tailpipe connections. Much easier to work on the sensors that way and well worth the few extra bucks.

Perfect Fit
Fairly easy install. I put the front end up on jacks and removed the passenger tire for ease of movement. Make sure to loosen the exhaust line at the mid-frame. Don't chance it, use new gaskets and use plenty of break-free before loosening the bolts. Take your time. You'll do better with narrow sockets. Snapped right into place with no issues. I have that weird All Wheel Drive model, so I was a bit nervous about the fit. Worked like a charm.
