I think this is the first VW I've owned with a stock muffler. Pics of quick fitting install here: http://65.170.133.65/photos/thumbnails.php?search=new+muffler&album=search&title=on&caption=on&keywords=on&type=AND 1. What's supposed to close the gap between the muffler "heat elbow" and the heater box opening? I've never had a muffler with the "elbows". Always had paper/foil tubing all the way from the shroud to the heater boxes. 2. What might cause the fairly severe offset between the left and right j-tube slip fits? Right side is tight up against the heater box. Left side is 2" or 3" out. Do I need to wrap a strap around the mustache bar and try to pull that side in before I install the half-circle clamps? G2
