    Hello, I've recently fitted a 2.0 tdi exhaust system to my 1.9 tdi. The exhaust that came off was the original standard seat system single pipe going to one box at the back of the car with single tail pipe.
    The system that has gone on is a klarius aftermarket again single pipe going to the rear with one box but only differance is twin tail pipes side by side.
    Problem is I'm now getting the owl cooing noise when changing gear at low rev's mainly 2nd and 3rd gear if you drive hard the noise is not there.
    Any help and suggestions would be appreciated
