It looks good either way, and in the end comes down to what makes you happy since it's your bike.
I personally wouldn't put a ghost pipe on, it's wasted weight, and I like the 2-1 look.......it screams performance. Sets the bike apart from the vast majority of baggers who all have 2 mufflers.
Attach the ghost pipe to a rope and use it as an anchor for your boat, not your bike!
I'm sure it's a fun ride now...
I don't think it'll work as an anchor for my boat... My boat has a Supercharged efi 502 putting out 650ponies. I'd probably have to use the whole bike as an anchor.
BTW the boat has dual exhaust and it definitely has the look of performance. I wonder if I now need to change it over to a single pipe
