Aftermarket Catalytic Converters for the R51?

I am getting codes for both left and right bank cataytic converters on my 2006 Pathfinder. I have 147K miles on the clock, so I am quite sure they need to be replaced. I have found the factory ones online for $530/ea, but wanted to see if anyone knows of a cheaper aftermarket option, that is a bolt on replacement.
Thanks in advance for your help.

Advance Auto has some Walker direct fit replacements for $155 per side. I have no experience with these particular parts but have been pleased with the Walker catalytic converter I had on my Jeep.

Thanks for the information! I looked at Magnaflow's website, and they also make a DF replacement. Only probem with them is that they want $1037 for EACH side!!! I will call up my local Advance Auto and order them. Thanks for saving me $800!

Always glad to help out a fellow pathy owner.

Give us some feedback on these if you decide to get them.

Will do. I assume that the bolts on the factory units are going to be rusted to hell and back (NJ vehicle), so I am going to buy new bolts along with the gaskets, and anti-seize them when I install them.

Good thinking. Also get a can of PB blaster and spray all the bolts several times before you remove them. Do this a few days before if you can.

I've gotten a few catalytic converters (direct fit type) from Rockauto.com. They usually have Bosal, Walker, Magnaflow and Eastern Catalytic Converter and the prices are usually a lot cheaper than from Advance Auto Parts as well as the other parts stores in my area.
