So I got my stage 2 put on about 3 weeks ago and I put my Magnaflow Cat-back on this past Friday, but I was wondering if anyone else's looks like this? I know stage 2 runs rich but I want to make sure and see if this is normal after a weekend of driving. I cleaned it off once on Sunday, but it is back to this again today:

 

on initial start up my car blows bluish smoke, my car is so rich on start up .. If someone was smoking a Smoke near the back i would be shooting flames across my driveway...

i want to get this fixed so im looking into local Tuning....

 

Yeah, when I rev past about 4k its giving smoke, and when I'm driving and revving it up i have been told that black smoke is visible. As much as I don't like it if this is normal then I will leave it be for the time being so as to keep my warranty since I guess GM says this is what it should be (any problems is there fault ) but if not I would like to take it to get this fixed.

 

Yep... my GMPP exhaust is all black on the inside after a day or two... better keep that washed off or it'll become permanent.

Just means the car is running rich... welcome to Stage 2.

 

Dude mine dont even have stage 2 installed yet and it looks just like that

 

Alright, just wanted to make sure it was normal .

 

the stage 2 tune sucks. It is crazy rich and has no timing to take advantage of the extra boost and fuel.

 

Yep same here.

 

After a day or two my used to look just like that, I have the 2.8 Pulley on, so it's not as bad anymore.

 

Well thanks for telling me now i will have my tomorrow but hey if any thing goes wrong then GM dealer can take care of it

 

Mine did this stock. I started it up in the winter to warm it up. It even left some spit black marks on the cement in the garage in a spray pattern. It eventually accumulated over the winter after letting it warm up to the point that i could see it pretty well.
