As the title states, there is a small leak in my 00 GS300 B-pipe before the cat and its causing CEL issues, rather than fixing the leak is there a better alternative? I know Carson has one but its $500 :-/

Get a muffler shop to weld up the hole.

You mean "headers". Like he said, bring it to a muffler shop. But I think it's the gasket for the headers.

So, I ordered a megan y-pipe to replace the factory one that the dealer said had the leak issue in , install went smooth but the ******in light came back on today FML....

Car is going to the dealer on friday and I am having them fix it for good what ever the cost is, the GS is showing its age as we speak. It needs new tires, ball joints, this y-pipe issue etc etc. I am in talks with my local Acura dealer to see if I can just trade the damn thing for an 06 RL.

BTW here is what the megan y-pipe looks like.

Did you pull the code? Which code was it?

It was P0430 before and now its P0155, something to do with the air flow meter.

Clean your MAF, and change your O2 sensors.

...AND make sure you Re-set your ECU!!!

I would go and buy some of that CNC electrical cleaner and carefully clean out your MAF, then do what rock-a-lex said and reset your ecu.

CEL code is P0155 O2Sensor Heater Circuit Malfunction (Bank #2 Sensor #1)

The leak issue with the megan y-pipe was faulty gaskets, the exhaust shop installed old crush gaskets from OEM y-pipe so there was a leak where the headers met the y-pipe. I'll be getting the new gaskets installed today and resetting the code. Going to cross fingers/toes/***** to hope CEL dont come back :ugh:.

BTW, if it does come back, should I replace the above mentioned O2 sensor?

As you can see from the above diagram that the the bank 2 has only one sensor on it which is before the cat so the only reason I can think the CEL code is coming on is due to a bad O2 sensor? Rather than engine malfunction?

Picture of the actual sensor



This is where the wire from the sensor loops up and plugs into the socket.
