I put the 2 into 2 on my 2011 mastiff. I didn’t like the sound that much. I took the original baffles out and installed thunder monster baffles. i like them much better. They’re definitely louder so that’s something to consider.

another little trick is to pull the original baffles and cut them roughly in half and re-inserting the back half and screwing them back in. maintains most of the back pressure and allows them to sound off some more.

Not sure if these Supertrapp 2 into 1 pipes from my right side drive 300 tire Big Bear Chopper Sled Pro Street 300 would fit a Big Dog, right side drive with a 300 tire? The engine on the Sled is an S&S Smooth 100. Lots of knowledgeable individuals on here so I thought I would ask? Replaced the 2 into 1 with the Frankie Serano 2 into 2 pipes, last pic.

Hi, I would like to buy similar exhaust system ( first pic.) for my 2007 mastiff 300 rear, RSD. Could you give me the hint, where I can find this?

Sorry but I am not sure. I just googled Supper Trapp but could not find any pipes that looked like mine. Assume they don't make them anymore. You could try to contact Big Bear Choppers do see if they can give you any insight?
