Hello, I was curious about the exhaust valve at the end of the exhaust pipes in the seat Ibiza 1.5 150hp. When the car starts up they immediately close and dont seem to open in any of the driving modes. I think they only open under full-throttle or above 3000rpm. Will disconnecting them cause an error code or a check engine light? I have also read it may diminish performance. Has anyone done it? Is it safe to do? The thing is, this is a company car and if they find out it has been tuned or some modification done to it, I could be at risk of getting in trouble.
Thank you!
Thank you!
