i was wondering if any one has put a catted zzp downpipe on a new cobalt sport besides me my check engine like came on tonite onthe way back from school so im wondering if its from the downpipe im prolly gonna scan it at work tomarrow just seeing if any one else has had problems

 

high flow cat=cel
welcome to the world of modified cars

 

ZZP claims it right on their website somewhere that their DP will set off a CEL. You can get it tuned out, or go with a different DP. Cobalt Addiction seems to be one of the best as well.

 

i beat you to it

currently i have no cel's


i'm not sure how he has just the downpipe

 

ZZP makes a DP that bolts up to the stock cobalt exhaust. Their shorty header and DP are the ones that only work with each other. Or at least thats what I thought.

I didn't realize you had ZZP Brick...

 

**** my Cobalt addiction set a CEL to.

 

get the zzp mid combo wit cat they wont set it off lol

 

yeah had to have my cel turned off

 

You turned that actual CEL off? I thought you could just disable the code so you don't have to turn off the CEL?

 

midlength combo

i'm going to scan again for codes today to make sure i didn't miss anything

 

ya it throws a catalytic low efficency code o well just means ill have to get a tune soon

 

mine took almost a year to start throwing cat codes, but you're almost guaranteed to get one eventually. i keep my code reader in the front seat.

 

thats what im saying.

 

Aftermarket ceramic core catalysts set codes.

Random Technology, Clear Image, and Vibrant all offer metallic core catalysts that dont suffer this problem unless your engine is running way out tune.(youd probably be frying stock cats too at htis point)

 

i still have the cell from last year when I put the zzp header and dp lol
