just like the title says:

is there an aftermarket cat that will past emissions/smog and not give a CEL?

the muffler shop forgot to give me back my oem cat when they put on my high flow, so now i have nothing to go back to. LOL

are there like aftermarket cat replacements that work just like oem? my high flow cat was good for abouth a month or two and then it threw a CEL. so i just want something that is going to be solid and not give me a cell.

 

Which high flow do you have?

 

i had a magnaflow.

now i have a test pipe running on obd1. but i'm gonna go back to obd2

 

I'd just find someone who has an OEM cat lying around and use just to smog then go back to your Magnaflow. Or better yet see if you can buy one that's what I would do! I still have my stock, that I use only when I smog...works for me...The rest of the time, I am rolling with the highflow!

 

Magnaflow highflow will pass, be sure the car is warm, my ish barely passed

 

I'm running a carsound cat and I pass all the time. You just have to make sure the car is warmed up really good. I run mine on the highway to warm it up fast. As long as the Nox level is low when you smog you should be fine.

 

i believe the random technology hfc passes everything... kinda pricey, but i really like mine.

i got a cel after 2 months of using it.

DO you guys that pass with high flows have an OBD1 or OBD2 car?

 

i used my magnaflow to pass, i believe the box said it was a carsound cat made by magnaflow, i dunno i threw the box away.
