ok so i have the dift spec catback from meganracing and its giving me a slight issue.

i have all this black soot coming out of my tailpipe and its really starting to annoy me.

i'm guessing the car is running rich but is this normal?

anyone else run into the same problem?
i thought it was a pcm problem and it may be but i dont have a CEL coming on

 

I own the same Exhuast as u and iv never had that problem.. but i also moved my forward a lil more and i have a ZZP DP which moves it out a lil more again.. so its either runnning rich or the exhuast is not far enough out...

 

i got ahold of a rep from meganracing and he said its the correct length. im gonna end up cutting it off and welding on a longer tailpipe. i'd rather make sure there isnt some other problem before cut it off.

 

its cuz its a megan lol

 

thanks for the help... next time just click the logout button if the thought of a smart-ass comment comes across your mind.

 

hahah calm down man, cant take a joke? Your probably running rich. You wouldnt necessarily get a CEL for that, are you tuned or staged?

 

nope nothing special on this balt just air-box mod and catback atm

 

ur running rich man. has nothing to do with the exhuast.

 

ok anything i can do to fix it?

 

Get it tuned, and you might as well get pulley and injectors too. The tuner should make your AFR correct and you can get a wideband to monitor it also.

 

no idea what is telling it to run rich since i only have 37k miles on the damn thing

 

well has it always put out the black soot?

 

no it started after i put the catback on

 

well honestly it might be the catback, ive never owned one....but every time i see a car with a megan or a can type of muffler, they usually have the black **** around it. Otherwise i would say its running rich. Nothing bad will come from making the the car faster with injector, pulley and a tune lol so try that haha

 

i will be getting ottp stage 2 soon. just ordered headers last night

 

maybe that will fix it, if not than maybe its just the catback. Maybe the cat?

 

that cat is going. im gonna weld up a new downpipe at work.

 

well theres your problem...

 

???

 

why dont u just move the hangers a bit... thats what i did.. i mean u are running rich so thats your problem. dont cut it ... just move the hangers forward like i did... then u'll never that problem period* for the love of god..dont cut it**!!!!! oh just by the ZZP downpipe. dont just make one** but ya..theres my 2cents*

 

if the cat is going...thats probably your problem

 

I moved my hangers got like a whole 1/2" of play, and thats not enough. i need like an extra 2 1/2-3"

 

that cat is fine. its going as in im gonna get rid of it.

 

oooooh, well then nevermind haha

 

so i guess for now ill just try to keep it clean till i can get staged and tuned
