What's the best catalytic converter to purchase?
Hello 
Curious.... if my cat is indeed dead and needs replacing, which
cat would you guys recommend? the high flow from custom-maxima?
another brand... etc etc....
Thanks all
EDIT:
I would be looking for something performant... hehe

However, for less than half the cost of a performance cat, it makes sense.

Actually you would get a nice little gain from the test pipe (3-4 HP) but if you are looking for a cat the will give you (it gave me about 1hp peak) hp try the Random Technologies High Flow cat it is a great cat for around 150. Brian

Do not buy the Random Technologies cat. While I was in the market for a new cat I heard numerous reports of people hating the RT because the inner honey-comb section broke loose and rattled around. I did not listen to them and bought it. 6 months later, rattle rattle rattle. I'm buying a test pipe.

Okay, what about this letter I saw on the maxima@lumiere list that was written by Mike Kojima? Makes me wish I kept my stock cat...
>>There is a signifcant difference between a OEM cat and
>>an aftermarket cat in performance. An aftermarket cat
>>typcialy has a precious metal loading in the matrix
>>wash of about 10 grams of platinum and palladium per
>>100 square feet of matrix. An OEM cat has a loading
>>of twice as much, 20 grams or more per 100 square
>>feet.
>>
>>So what does this mean? An oem cat has a conversion
>>efficency of nearly 100% to 95% while the aftermarket
>>cat is only 70% at best when new.
>>
>>You are way more likely to pass with a new OEM cat
>>than an aftermarket cat by a margin of 30% even when
>>things are nice and new.
>>
>>Nissan OEM cats do not have a performance disadvantage
>>of the supposed hi-flow aftermarket cats. I have
>>measured a drop in 5 wheel hp woth the random flow
>>high flow cat for the 240SX over the stock Nissan cat.
>>
>>I have ran a cat on high powered NA car with only a
>>loss of a couple of hp over a straight pipe.
>>
>>Nissan cats are superior to the aftermarket.
>>

I was victim of the RT Cat falling apart after 3 weeks of use.
And...my buttdyno tells me my car pulls stronger thru the whole rpm band with my old stock cat on. Of course the RT Cat might be better.....perhaps mine was faulty from the get-go despite looking fine and being new?.....
