Ok I bought a Catted ZZP downpipe and the CEL came on about a month ago and has satyed on. Should i buy a defouler will it clear it, or should i put my stock downpipe on. Need advise Asap Thanks..........

 

Have you scanned the code to make certain its the downpipe? If it is then the defouler should work if it doesn't have one. Putting the stock one back on will also work but then you've wasted your money on the downpipe.

 

mine did the same thing

 

buy the vibrant defouler from mpx I have it on my catless and never had any codes.

 

either the defouler will work or get the o2 cels taken out by getting a tune

 

thats what i did

 

Hmm ok i think ill try defouler then if that doesnt work tune :/

 

Its not a big deal. P0420 will be the code most likely.

Go to any oreilly, autozone, advance auto and get it cleared.

It doesnt affect anything

 

there are over 1000 possible causes of an engine light being on. pull the code and then diagnose it.
