Since I have nothing better to be doing at almost 2am in the morning, I have tried a few more things. Here are 2 more pics of it again from different edit options. They both show it coming from the tire and it really looks like a stock can.
I hate to bring up an old thread but st couldnt stop looking at the picture. Upon closer inspection if you follow the contour of the rear tire you can see that there are 2 tires and the second exhaust is the exhaust of the bike behind it. The angle of the picture gives the impression of there being only one tire when in fact there are two of them. Again sorry to bring this back but it was just bugging the hell out of me.
