2004 Nissan Quest - universal catalytic converter ok?

I've bought a few that were OEM fit, but not OEM with no problems. Check out Summit Racing for pricing. Thats where I bought mine.

Thanks - I checked out the site but they don't seem to have one for the Quest - just lists it for the Frontier and the Xterra... are 'univeral' cats not really 'universal'? If so, does anyone know where to get a non- factory one for the Quest?

Check at your local Meineke, Midas, or other muffler store.

I don't know how you could have a "universal" cat,as the flanges are different for different brands,flow rates are different for different engine sizes,tubing sizes different,cat lengths are different.

A "universal" cat would require you to cut off the pipe close to the old cat,and use U clamps to secure the new cat on the old tubing.No "bolt-ons".

Any extra help from Nissan on this known issue? Or is this another of Nissan's "we built in a manufacturing defect but once you are out of warranty we don't give a $hit".

To the OP: Check your local auto parts store. They can get you an aftermarket cat that will fit like the original at a reasonable price.

Meineke is telling me that I have to go to Nissan to do it...

I asked about him getting a 'universal cat' and fitting it in there & he said that since it's an ODBII system then I need the factory converter part or the system will keep throwing CEL's.

Is this true? I'm still waiting to hear back from Monroe & Midas, but the Meineke guy said there aren't any aftermarket cats for an 04 Quest.

no,all you do is put a O2S spacer in the cat bunghole,then the O2 sensor. It's a spark plug "defouler" drilled out to pass the O2 sensor. They are sold on Ebay,or you could make one yourself.

the spacer should be in the DOWNSTREAM O2 sensor position.AFTER the cat.

do a Google search for "quest aftermarket catalytic converter".

Wow - that would be great if I could get it working. The Nissan car is like 4 or 5 times as much as the Magnaflow 93500 you pointed me to.

Just to be clear though - the two problems I've been told about trying to use a 'universal' is 1) the ODBII computer stuff will throw codes since it isn't the 'stock' cat and 2) it's the right front one which I guess attaches right up on the engine so there isn't a lot of room to work a generic one in there.

I'm planning on getting the parts I need and having a local garage I use install it since I'm not into non bolt on (welding, cutting, etc) stuff too much.

I want to be able to make sure I have all of the parts they'll need and also make sure it's going to work instead of just taking it in there & possibly wasting their time.

For this ebay thing - what words do I search on to find the adapter I'm going to need. Also, other than the ebay part and the mangaflow are the only other parts standard exhaust tubing?

Thanks again!!!

as long as the cat is working,the computer will not know if it's OEM or atermarket,as long as the downstream O2S is installed after the cat.(to monitor it)

Yeah,that's the real problem. They put the cat close to the engine to get the cat hot faster,the exhaust gasses lose less heat over the shorter distance. I don't know if you would be successful at subbing that cat.Uni-cats are not really made to fit in there,but for under-body apps.

"O2S spacer" or "oxygen sensor spacer".

Well,you have to cut off the old cat close to it's body to leave enough tubing from the flange to mount the new cat. with that Nissan style cat,you may not have enough room for a uni-cat,and the uni-cat may be too long to fit.

I think you may have to "bite the bullet" on this one.
