I need to pass emissions and my after market cat just isn't cutting it. Let me know if you have one available and thanks!

 

I have a OEM Cat from my SI 80.00 shipped to you

 

Cool...you mean not gutted or molested in nay way? If I were to pay the ridiculous $1100 at a stealership I would be getting the same thing as you are willing to give me for $80? I've PM'd you, so just let me know and THANKS!

 

does the cat need to have the threads for the secondary o2 sensor? i have the cat but the whole was plugged. i'm not too familiar with 99-00 si's. lmk. i can let that one go for $70 shipped.

 

Yeah I need the secondary O2 bung. That is why I am throwing the code actually. The sensor is completely missing and I don't think my magnaflow cat will do a good of a job as the OEM cat. I'll see when the shop puts it in. I don't feel like crawling under the car for this job.

 

I have a seconday o2 for the Si .. also an OEM cat from a 2000 Si, its a drop rusty but if u want pics let me know.

 

I have a cat in great shape from a 99 si. I also have a test pipe and a sim-chip so you wont throw that secondary o2 code.

 

Thanks you all. I had my sec O2 sensor put in and it's OK. The magnaflow cat does a good job and doesn't throw the code. I do appreciate all of your help. Take care.
