Muffler for Car

I designed this muffler years ago for my old SAAB 900 Turbo. All parts are made of stainless steel sheet metal except for the transistions which are cut and formed pieces of stainless steel pipes. Everything welded together with "muffler rolling" inside (not sure about that word but i´m sure you get it). It´s designed to fit on a 3" exhaust system.
