Hey guys been a while, I'm still on the fence of selling my Monte but would need to pass emissions and right now I don't have a cat converter.

I was looking at getting a High flow cat but one to clear the 02 sensor light as well. Is there any suggestions on high flow cats and would I need to buy an o2 pass for it as well?

I have an 06 Monte SS

Here's one I've found comments suggestion appreciated!

High Flow Cat Converter

 

Bump?

 

a high-flow is still going to throw the light, gotta get that code tuned out

 

You don't have to actually get it tuned out.

You can space the 02 sensor with a spark plug defouler and it will get rid of the code.

You can get those at basically any autopart stores.

 

Anti foulers or build your own 02 simulator,

 

Anti-foulers don't work on 05+ I think

Because it reads more than just the cat

 

I've read that they work on GXP's with no issues, should be the same.

 

thats wiered when i put on a high flow cat on mine didnt need a tune. but i know they checked the computer to see if it would throw a code they said they were waiting to see if it would if it didnt they wouldent do any thing extra as in telling the computer to say it is fine where it sits. but to behonest i dont think you will need to do a tune on yours. but i do have a question why are you debating on getting some chevy model tired of the two dors

 

it was a simple question besides i ment doors
