Germany is a trap. There's absolutely no freedom in modding, because you have to get it certified by the TÜV (kinda German DMV). Even, by logic thinking, you know a dual exhaust is not gonna cause any differences in the exhaust gasses, bacause you mod AFTER the cats, you still have to get it tested. That's gonna cost! :banghead:
Now, I am not totally sure about this, since there are some rules on this. The body is already prepared for double exhaust and there are CTS types with dual exhaust, so there might still be some light.
But I have the same problem with the CAI. Though, I can simply havethe CAI replaced by the OEM again when I bring it in for the tests.
You even have to certify any different rim size! Even if it doesn't effect the outer diameter of the tires!:annoyed:
Well, learned another thing...
