I need to replace mine too... I'll find out on Thursday what the damage is anticipated to be. I'd love to know if there are cheaper options that worked for others. I'm pretty handy, and I have a good set of tools... Any Magnaflow, Walker, or other 3rd party vendor success stories? Did you replace the front or rear or both?nutbar78 wrote:So these R51 V6 trucks have 4 cats right? If one or two go bad, can't we just put some plain piping in with a threaded bung for the O2 sensor? I mean instead of replacing the cats?
That's what I'm afraid of... I think I can do the job but I'd hate to end up having to go to the dealer anyway... I've read about Walker cats failing in a year or two... While some have mentioned the MagnaFlow cats no follow up reports have been given on their durability. I hope someone with firsthand knowledge of the situation offers viewpoints before I commit to a dealer repair...smj999smj wrote:As far as aftermarket vs. genuine Nissan, they are usually cheaper, but stick with a reputable, name-brand converter (ie Walker, Bosal, etc.). Some discount brand converters have been found to not up to OEM specs and the MIL will still set after you've installed it.
