I’m going to put new exhaust on my 2007 K9. Please give advice, pros, cons on the systems anyone who’s has upgraded. I do want 2 into 1 big radius and of course don’t want performance jeopardized, but (yes I’m a girl)
looks for me are the biggest factor. Also, want a system which is easy to install without a lot of customization involved. TIA

There was a guy on FB Big Dog Chopper's page selling a set but it might be gone. You have to look as the BDM was bent specifically to clear the RSD and the bracket was specific as well.

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.
