So my catalytic converter crapped out on me . Was wondering what brand name catalytic converter is a good bang for the buck (want something that is quality and that wont keep my CEL on). My cobalt is an 06' S/C

Any input helps alot thanks!

 

Zzp 2.5 downpipe with a high flow cat

 

go catless imo but if you must have one what 574 said

 

Cat or dp?

Stock d/p replacement, lol?!

 

you will get a CEL with a high flow cat though, so you'll need an o2 defouler as well. This is the cheapest and best replacement.

 

Where would i be able to buy an o2 defouler? Is it listed somewhere on the zzp website that i did not see?

 

auto parts store or order online, i think its in options on zzp when you order

 

Guys I have a catted dp with a defouler trick yet still achieved the CEL. Those sensative O2's lol

 

Is there such a thing as an o2 plug out there? I ordered the zzp downpipe and high flow cat, but i have an o2 sensor before and after the cat (06 s/c). The problem is one of the sensor is in the headers so now i have an extra hole i cant plug on the downpipe. How do you get around this?

 

Take it to the chevy dealer...if ur car has less than 130k miles, they will replace it for free..in most cases.....

 

replace the dp i bought from zzp? im confused lol
