Is it a common issue when buying the catted down pipe to get a check engine light saying the cat isnt doing its job because its high flow?
 


Yeah its common just do the spark plug non fouler trick. If that doesn't work then you prbly need a new O2 sensor. Did it work before?
 
yup i had it then i reset the code its fine now. i emailld zzp about it. they told me i needed to buy a canned pcm from them so it will turn off the code
 
I haven't bought it yet. I was asked if I wanted it for Xmas. But if it throws the code my parents said its on me cause it won't pass inspection so I was debating on it. And what's the non fouler trick
 
When I bought mine ZZP offered a "built in" non fouler. My cat code has tripped twice since then. Its been over a year since I last reset it.
 


what year is is your car? the 01 dont like the o2 to be deleted.

you could find a local to tune it off if its not a 01. if its a 01 your want to try the flouler trick for sure.
 
It was one of the options when I got mine. It was a "No SES" option or something like that. Last time I looked I think they stopped offering it. Any non fouler available at a parts store will keep the cat code away.
 




Ordered the down pipe. For gaskets do the stock size work? Or do I need to order them from zzp also. I was hoping I could get them at advanced
 
stock sizes work. and dont be suprised if you snap the bolt off in the cat back flange. I know i did and many others. I only had 35k miles on mine when i snapped it
