Today I drove my 1,2 VTI with my backseats down and therefor I noticed more sound from the exhaustion than usual.With normal driving 2000-3000 RPM there wasnt any sound. But when I did a fast acceleration above 3500 rpm the was a sound from the exhaustion almost sounding like when you got a hole in the exhaustion.
Is this normal? Maybe others could try it out ?
