replace catalytic converters?
so my CEL light is on and throws the infamous code for "bank 2, catalytic converter or oxygen sensor" error . i forget what the exac
anyways, took it to dealer and dealer says both cats are bad and need to be replaced in order for me to pass emissions inspection in VA.
what is the avg price to get this work done?
dealer quoted me a discounted price of around $1800 (says reg price is $3k+)
does it matter if i use OEM cat converter or is an aftermarket cat just as good?
i've been having issue after issue w/ this GS. i thought it was a solid car, but now i dont know. been thinkin bout getting rid of it for a 2002+ Q45, but i really like this GS.
any advice on what to do about my catalytic converters would be greatly appreciated. thanks

You might want to check your exhaust pipes for any leaks. I have a leak in my Y pipe connecting my manifolds to my cat converters, and it's giving off a Code - P0430. Checked the O2 sensors, and they were replaced at the 90k mile service. Had the cat checked out, and it's in perfect working condition. My Y pipe is throwing everything off balance.

i currently have a greddy PE full exhaust on my gs4. it does have some rust holes in it. (i taped it up w/ metal tape) maybe that is the leak in the exhaust causing the P0430 code??
i bought this gs4 from a CL member named kevin. he neglected to tell me the exhaust had holes in it and one of the rims were cracked. i know i shouldve taken it to a mechanic first, but he shouldve also disclosed this info to me. oh well, nothing i can do now.
i have a stock exhaust sitting in my shed that hasnt been used for a while.
i've been thinking about getting rid of the greddy PE exhaust and putting the stock one back on. how much would an exhaust swap cost?
the problem is, I don't know what the exact problem is. dealer says its the cats (but i dont believe them 100%), could be exhaust leak on my Y pipe, could be bad 02 sensors
how would i go about determining the exact problem?
thanks for all the advice thus far.

Well for this you would need a lift. I have a friend with a garage, so he was nice enough to let me use his lift for a while.
I went under the car, with it turned on of course, and placed a feather across the piping to see if there were any leaks. If there were any leaks, I would note it on the diagram that I drew ( which i lost lol ) The only leaks that I found where in the Y pipe, and the gaskets connecting the Y pipe to other pipes. The gaskets needed to be replaced, bought them for about 5$ each. That stopped the leaking from the gaskets, and the Y pipe is still in need for a change for me :P
You might also want to have your O2 sensor checked out at a trustworthy mechanic. Check your maint. records, they may have been replaced.

cool...i will have to try your suggestions out
i'm pretty sure my exhuast has some leaks, cuz i dont think that metal tape is good enuff to prevent leaks.....
i think i may do the exhaust swap first (get the stock one back on), then see if the problem persists/CEL light on
if it does persist after exhaust swap, then i will check 02 sensors and cats

i recently had my starter replaced and this CEL p0430 code popped up shortly after.
while they were installing a new starter for me, the mechanic calls me up and asks "has your car been idling rough?"....i said "no, it was perfect when i brought it in"
when i go pick up the car, i inquire about the rough idling issue he mentioned and he told me that they fixed it cuz they tighten some manifold intake.
would this be the same thing you are refering to? sorry, im not an expert at cars, but i sure am learning alot!!!

hahahaha....i hope i dont pass out...the hole is taped up, but prob not a good solution to the holes...
anyways, how much do you think it should run to put a stock exhaust on ? labor only, i have the parts...
im sure its much less than 1800

how would a mechanic test an o2 sensor?
is there some device like the obd2 scanner/code reader?
so you ended up replacing the cat converters and you still had a problem? then you replaced the o2 sensors and everything is ok?
