Well as some of you know that i had a problem with my car blowing blue smoke when I took out my last small cat. I just put on the stock cat and nothing! No more blue smoke! I'm so happy! Never again taking it out. (alright)
 
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

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
 
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"
 
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...

You have a very good point. But no one with their 2008 ms3 had problems with the blue smoke. Mazda cant hide this issue. I payed 24k for this car and if their is anything wrong with the turbo, I will promise you they will replace it.

Yah, if you check out the next to last page of the thread I posted, guy named voicekoil says that apparently they have some test they can run to see if the turbo is leaking, even if you have the stock exhaust on...
 
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.
 
yeah i do like the sound with out that second cat though a freind has the same setup as mine but with the testpipe and it is sounds seriuos! mine is nice his sounds like a true warrior...

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.

Its not a significant amount of oil... You should not see a difference in oil level. Remember, that a small drop of oil creates a huge cloud of smoke!!

The actual oil leak from the turbo seals is probably a light mist, but its enough to cause a smoke cloud!!!

I say get it fixed ASAP!!!!!
 
The last muffler looking thing is really a muffler.This car has 2 resonators and 1 muffler and 2 cats stock.

a resinator is a straight thru design thats what the "muffler" looking thing is, just cuase it looks like a muffler doesn't mean it is one... a muffler a many chambers nooks and crannies
