my car has started misfiring and i fear my cat may be getting clogged from this, so i am considering gutting it, to those of you with a zzp catless dp and a stock tune, do you throw a code?

 

yea any catless dp will throw a code, you can disable the code through hpt though.

 

alright i was just wondering because right now, because it randomly throws the code saying the sensor isnt seeing a change in exhaust flow so i thought losing the cat would stop that, but thanks for your response

 

Ive had my catless on for 6 months now and I havent received any abnormal codes

 

I haven't received any CEL since installing the ZZP Catless DP in July 10. Car has been flawess with the GMS1 running the Catless DP.

 

sorry I can't help...I tuned right after putting my dp on...

 

mine never threw a code. Although i have a vibrant resonator in the cats spot.

 

wait i forgot one thing... are you sc or tc?
i believe the tc catless downpipes have angled 02 bunges so that way it wont throw a code.
basically it works like a defouler. i on the other hand have a lsj dp which does not have the angled 02 bung which is why i throw a code.

 

i have a ss/sc with a zzp catless dp and i am throwing a code

 

the lnf ones have the j shaped not angled
