so what did you take out that cuased the blue smoke the second downstream cat? midpipe?? or downpipe? this would be helpful as i'm conserding getting a midpipe
The issue was not the cat; you have a turbo that's burning oil. Bigger issue than just a little smoke and the cat is just masking the issue...
See here (long read, but worth it):

This started happening when i took out my car. My cr had only 1500 miles. So your telling me on a 2008 brand new car the turbo is bad?
I'm saying that blue smoke is burning oil that the cat can not be causing. It is possible that the stock cat is hiding the issue from you, but there is no way that a cat can CAUSE an issue like that...
THANKS!!! i have all 3 resinators cut out with no problems i was about to get rid of the green one, i might rethink that... ps it sound great with the resianators cut out
3 resinators? I see only 2. Where is the other one?
the last muffler "looking" thing is really just a straight thru resinator it just looks like a muffler
if you check out the vid on the front of my myspace page thats what it sounds like with both cats and no resiantors from there "striaght pipe"
The cat in the downpipe and testpipe are there to convert the exhaust gas, by removing them, it makes the problem more noticeable, throw back either one on, then the problem is gone, thats what they're there for. The problem is, the speed6, speed3 and CX-7 have weak turbo seals, so when anyone removes both cats from the exhaust then you will notice the problem more.
So if our cars have weak turbo seals, we should be losing oil. But now i will check my oil level everyday to see if it's true.
