I have a 2004 gs300 stock and need to change my catalytic converters due to p0420 and p0430 code. I was wondering if a 2jzgte manifold fits my stock if I buy one? Any suggestions on which one I should get? Like I said everything is stock n have 290xxx miles

I would say yes, but what would you do with the flange's since the GTE is turbo?

Technically it would bolt on, but will not work OP. As the GTE is a turbo manifold....and were assuming you have the 2JZGE motor, which is NA since your car is all stock.

Don't just assume you need to change your cats. Do some searching on here regarding O2 sensors and exhaust leaks.

Even with those codes, it is likely not the cats.

Dont forget, you're in California. Removing the cats is not an option.

So this means it would need a turbo set up to go with it or a whole new swap in order to work.
My best option would just get a one that fits my 2jzge non turbo?

I changed a o2 sensor n this codes came up was told it was the cats but il take another look for leaks before concluding it's the cats
One more thing to add that might be important is that my rear bumper is turning black due to the mufflers maybe the cats

Getting one for a GE is your ONLY option, unless you plan on spending thousands for an NA-T
