Can someone help please?
 

Hello,
I have a 2003 Audi A4 with the 1.8t engine in it. Recently I bought this 3" test pipe for my car:
High Flow Testpipe Test Pipe Audi B5 B6 A4 1.8T (VW Passat) 3"

When it showed up it looked good and all was fine and well until I tried to put it on, I screwed in the o2 sensors first because I figured it would be easier to install that way. When I went to install the pipe i noticed that there was a little bit of space between the turbo outlet and the pipe, I looked up and realized that the front (pre-cat) o2 sensor was hitting the exhaust manifold. I do not know what to do about it, is the test pipe made wrong with the sensor holes in the incorrect place, or is there something else? I've tried everything I can think of and I've been told you cannot use spacers on your pre cat sensor.
