I took a look through my photos to see what I have. From my last 3 bikes, I have a total of about 10 photos of the left side and a few hundred from the right side...plus about another dozen from the rear and another 8 from the front. The photos from front and rear were mostly taken showing the front and rear, along with the right side of the bikes. I'm more than convinced that I favor the right side photos. Again, if I had a center stand, I'm sure I would likely take more photos of the left side, but since I don't, I won't.
To go one step further, I checked out photos of cars, and it looks like everytime I ever took a photo from one side, I also took the other...so I don't just have some general propensity to photograph everything from the right side...it's just a bike thing I guess.
I don't know what all of this has to do with liking one pipe or two though. When I got my D&D's, I only got the 2-1 side originally and added the chrome belt guard cover. I just didn't like the looks without the other muffler. That's a personal choice. I don't think that it's something that we can argue about on here. There is no correct answer, except on an individual basis. When I ordered the ghost pipe, several of my friends made fun of me...until they saw it on there. They all agreed that it looked better.
The worst part of it is that we, as the riders, only see the rear of the ghost pipe sticking out the back. When you are riding, and the bike is upright, it's others that see that ugly rear sprocket. I may have stuck with one muffler if there were an easy way of making that rear sprocket chrome, but that's not the case. You can't even get a chrome cover for it. I may have very well lived with it, given a chrome rear sprocket, but I still think that eventually, I would have ended up with 2 mufflers. Again, it's a personal choice.
This is one of those topics that I think we all just have to agree to disagree on. Happy holidays everyone!
