Re: Smoke after uppipe/dp install
I have noticed a lot of smoke coming out my tailpipe when idling. I just installed an uppipe and a downpipe and am new to all of this. Please tell me if this is normal or not. I have also included some pics of what it looks like:

If it only does this for a few minutes, or for the first few times you start the car after the install, you may be burning off any oils that may have been in/on the new piping, as well as any wd-40 or anything like that you may have used to loosen the bolts before removing the original system. If it keeps smoking for a while, you will need someone with more knowledge than I have to reply to this thread! 
I hope it goes away for you.

You're fine: since you're running catless now, there's gonna be more smoke coming out the tailpipe. Also, you should've also noticed that it stinks like a hot turd in the sun too.
If you ever get pulled over, pray that the cop isn't sharp enough to notice the smoke or smell

yup it will happen since youre catless now. most of it should dissappear after the car is warmed up.

will i have either the smoke or the smell if i get Vishnu UP, the COBB DP with cat, mated to the vishnu cat back exhaust?
i would guess since i'd lose two of the cats but prolly not as bad as totally catless?

Well I have had the uppipe and dp on for about 2 weeks now and even though the car is not cold, sometimes when i idle it does this. I figured it was normal but I am new to all of this. Thanks for all the help!

Did you reset your ecu after the install?
It is normal, but if it is still smoking significantly when up to temp. you might want to do a reset. That might help.
I have been running catless for a couple weeks now, and haven't seen any extra smoking since the first day.

Really shouldn't be smoking like that. Mine nor any other that I've seen smoke after putting those pipes on. I agree that it could be burning something off that you may have used like some type of grease, oil, etc. Are you used to telling things by the smell? Everything has a distinct smell to it like oil, coolant, and such. They also have different colors. The pipes could also have something on them from when they were machined/made that is burning off. Are you saying it is doing it after it has warmed up? Takes a few minutes for the pipes downstream of the engine to really heat up and downstream of the turbo. You shouldn't have any oil leaks unless you did something by mistake during the install. Look around the area that you worked on for any signs of oil.
