/6 Exhaust: Dual or single? Your thoughts
I've run headers and true duals. I liked it. If you want nasty, I think you'll want duals.
Back in the day, Dodge and Plymouth had a high performance single exhaust, which really sounded mean, but I think it was only a v8 option. It had a baloney sliced big rectangular attenuator. As big, or bigger than 70 Cuda tip. I don't know why nobody repops those, they were awesome. If they sounded that good behind a six, I would conside one of those.
