I had always wondered why some bonneville SEs had a dual outlet on the one side, and you 93 SLE owners cleared that up for me. I'd like to add this to my 97SE at some point. A few questions, is that the same muffler with a dual outlet, or is it a different type. And does GM stock them, or should I just get an aftermarket unit. I don't really care about added HP or making a lot of noise. But I love the sound of the 3800 (especially when it starts) and I'd like to make it a little louder with the look of the dual exhaust.
