95 Jetta GL AWD conversion kit

Hi all I'm new here http://www.volkswagenforum.com/forum/images/smilies/biggrin.gif,
anyway i have a question is there a AWD kit/parts that i can get for my car and will it fit it. Because that center channel under the car is being taken up by the MagnaFlow Exhaust i have on the car. and if there is a kit out there i am very curious on how it would fit in there. Or if there is no AWD kit is there a RWD kit?

Thanks
