Hello,

I have a 2001 RX 300.....Had that rotten egg smell recently from exhaust...thought of the cat converter...

What is the warranty on the cat converter for this car????

Thanks in advance...

Lexmex

There is a federal emissions warranty that all manufacturers must meet, 8 years or 80,000 miles

Where I live, the low grade gas is high in sulfur and I can smell it out of the other vehicles.

If you are no longer within the warranty period, consider getting a Magnaflow High Flow Cat like the one on my RX. I believe last time we talked about it, it was cheaper than stock and from my experience does a way better job, even with my not having precats.

Just be aware that some counties/states are now requiring annual emission tests. I know that OEM equipment on all RX models meet that minimum standard. If you change any component, the new must match or exeed that level. The list of counties keeps growing each year.

[If your vehicle did not meet the emission standards when it was manufactured, you get a waiver, but you fail if you modify the system and fall short]

Lexmex pretty much sums up the best option and the Federal warranty. Magnaflow also has a model that is CARB legal, which means it is good for passing California, in addition to other 49 states.

My Magnaflow high flow cat passes me better on the gas analyzer than it did when I had my OEM cat and precats, (both done in due to damage from the road and gas, respectively). The Maganflow high flow cat takes the place of the 3 way system, so you should have no emissions issues since it is superior to the OEM cat.

In California you can fail even if your car passes the tailpipe test if you are using non-OEM cats and they spot it. Doubt it would ever happen, but the laws are pretty strict about it.

I went non-OEM on my other car and the HC numbers were really low.

Your 2001 RX will not be tailpipe tested, if ... There is no check engine light when you arrive at the emissions station.

They will plug into your diagnostic port at the base of the dash. This will readout your OBD II, and it will pass the emissions testing.

The test does activate the check engine lamp and the operator checks to insure the lamp can be illuminated. The test then "OKs" the testing with a pass certificate.

Lexmex

That was actually the first thing I noticed, low HC numbers, after going with the Magnaflow. Love getting that unburned gas as low as possible, rather want it burned in the combustion for more power.

That is true about CA, they spot just about anything.

There are people down here who race at my track who go catless (illegal just about anywhere just not enforced) and they just bribe at the emissions testing station. Not to nice for the environment and I can smell it.

Lexmex

Even without the precats (I advise against this unless you run into the problem I encountered down here) have not had a single exhaust related CEL, though a few P0171 errors. Nothing that cannot be fixed with my Actron scanner.

Mine just passed the 85K milles and the precat(?) closest to the exhaust manifold under the firewall busted open. Could this have been because I have a bad O2 sensor (P1130)?

If not, why else would it have busted?

Any idea of the price of the OEM part? If I eliminate that one, I would have to eliminate the one behind the fans and noice would go up inside the cabin (drone).

Leonardo:

Are you talking about the "flex coupling" ,,, braided steel piece?

Salim

Leonardo

No, I'm talking about the catalytic looking piece coming from the rear (under firewall) side (bank one?)

Exhaust leak is felt/heard coming from the heatshield and there is a heat spot on it that indicates that it is reciving heat from under it.

Lexmex

Leonardo,

If you dump one precat (one of mine was damaged) you have to dump the other. There should not be a noise problem...that usually comes with playing with the resonator and muffler (which I have done many times to get the right sound). However, the OEM cat alone is not sufficient enough to reduce emissions without one of those precats, only a 3 way cat (that combines the process) can do this, such as the one I have from Magnaflow.

Bad O2 sensor would not cause what occurred in your case, but with the leak it can throw off the sensor readings even though the sensor before the cat but also remember there is a another one after the main cat below.
