Hi Wally,
I am not sure how the muffer in constructed as it was made by a seperate specialist muffer shop. When I got my hands on it was all welded up.
I know that it is glass filled.
The height was important in the design because my beetle is quite a bit lower all round. I had a simillar exhaust on the beetle previous but the bad points were the distance below the apron that it hung, (stop draging it on drive ways), the muffler was not supported so it kept breaking manifold bolts.
This setup is miles better.
