Good morning everyone. I ask about a problem with my vehicle. A few days ago I hit a stone and it affected the exhaust pipe somewhat because afterwards it felt like a whistle, that is, it had broken somewhere. Anyway, I went to a workshop and there a section of the exhaust pipe has been changed, from after the catalyst to the pre-silencer, approximately 50 or 60 centimeters of pipe. The point is that apparently after that the car feels like "locked" or "locked"; that is, as if he could not release all his power. It will be for the changed tube ?, or coincidence nothing more with another fault. Thank you.

Thank you. I have gone to a workshop and then to another until finally and apparently, I came to one where they do understand this. After reviewing, suspicions that something was obstructing was stronger. First the lambda probe was disconnected, and in that state, to test the car. It turned out to be that he evidently had the thrust of antecedents because of the fact that through the orifice of the probe, the gases came out more easily. Then, they reviewed the last silencer and at first glance it seemed very wet inside, so we decided to take it out and open it and there the surprise. It turned out that inside it had a fully rolled or wrinkled metal mesh towards the exit, so the passage of gases was difficult. In addition to this, they noticed that the spout was also clogged with the internal fiber of the silencer. They cleaned everything, new fiber, close everything, place and now. Before, try the car again without the silencer to feel it ride and check the power, which was obviously like before, that is, excellent. Then, once placed the silencer, all great. Conclusion: I had an improperly installed silencer because I should not have the metal mesh (as they said), and the fiber was possibly also poorly placed, that is, inside the silencer where both pipes are located, the outlet and the input (second compartment); when the fiber should only be placed in the first and third compartment of the silencer, just to avoid being absorbed by the internal exit and entry pipes.
