I couldn't help it! These are highly polished stainless steel mufflers. After 30 years of looking at dented/galvanized Corvair turbo mufflers, (they were the hot setup in the '70's) I decided to 'go for it'! (actually, Ram Air sold them to me for 20 bucks extra) These are a straight-through design. The mockup took about an hour, so I thought 'why not'? I started it. Nothing was welded and the floor jack was holding the X tube in-place. It sounded GREAT!
