I am wondering what the difference between a dual style exhaust and a shotgun style exhaust is, can some explain or show some picks of what they look like on a Dyna's? I was told mine are dual, but I wonder if they would be considered shotgun to, the tubes don't connect to each other with a balance pressure pipe. I have Rinehart Churchills.

I ask because both Rinehart and Superchips (reps) consider what I have a dual exhaust. But I think they more reflect the shotgun style,and I don't know if it effects the programming on my tuner. When tuned I get what seems to rich of a fuel feed and get a flooded pop from my throttle body and hard starts when starting (mostly hot motor starts). When I remove the program and go back to stock, it starts perfect but runs hot. I also have a Big Sucker intake. Maybe I just need to find a better tuner, time to save some cash.

<p>I believe the reason they refer to the Churchills as a dual exhaust is because they are 2 separate pipes not joined by an expansion or crossover chamber even though they exit on the same side.</p>

That is also what I was thinking. But, do all shotgun style exhaust have the crossover? On my old sportster I have slip-ons, with the Street Bob I have the Churchills, I have never ran another pipe, so I don't know it the crossover is what defines the difference between a shotgun or a dual.
