Stock muffler

[PLDXSR5]

Hello All..

New member here. I'm unable to create a thread so I hope someone will see this..

I just bought a 2000 Toyota SR5 3.4L. I bought it knowing it had an exhaust leak. I ordered the walker kit from RockAuto as well as the secondary catalytic converter.

The parts just arrived today. Both the catalytic converter and muffler part have inlets for an O2 sensor. I know there is an O2 sensor connected to the first cat, and if i'm not mistaken, these cars only have two O2 sensors.

Can someone please confirm if I purchased the correct parts? I contacted Walker prior to purchasing the parts to make sure I'm looking at the correct part(s), but I'm puzzled with this additional inlet that i'm seeing.

Part Numbers: Walker WK 55054, Walker WAL 16535

Thanks in advance.

Jon

TTT. Please read above comment.

Does the muffler part simply remove the rear cat?

I'm located in PA..

I have a 1997 limited with federal emissions, My 4runner only has 1 cat. the main muffler portion you have maybe for a federal emission car, and the second cat may have been available for California emissions. I am not as familiar with the newer ones, but being in PA you may not have that second cat, as most California emissions require a secondary catalytic and secondary monitoring oxygen sensor.

The converter you bought is for a California Emissions exhaust and the muffler is for a Federal exhaust. So no - you did not buy the correct parts. You need to figure out which one you have....look at underhood sticker. Use the e-catalog look-up on the Walker website to see schematics w/ part numbers for each of the two options.

Thanks for the reply..

Looking under the hood of the 4runner, it seems like my vehicle was built for California emissions so I went and ordered the Walker 54681 Muffler. So, I'll be returning the one I have now. Keeping the cat, however..

Yes, that looks to me like the California sticker - I have the federal version and it says not to be sold in California. Suggest you also get under the truck and look at the exhaust and make sure it matches the Cali parts you bought already. There is always a slight chance that a previous owner installed a used hood. Good Luck...
