I finally got around to installing my chrome, slash up D&D 2:1 Boss Fat Cat for my 2010 SE Ultra. Since I have engine upgrades, it was recommended by the shop that did the headwork (Hillside) that I get the big bore baffle.
I personally prefer the look of a touring bike with dual exhaust but I'm also open to new looks. I've also made the TP detachable, so the bike also sees alot of time in SG mode.
I'd be interested it what others think about leaving the ghost pipe on or off. I took pics both ways so feel free to comment on which "look" you prefer.
BTW, the bike sounds and rides awesome. I was previously running with stock exhaust with the catalytic converter removed and Fullsac 2.25" baffles. It sounded good before but it just sounds so much better now. It's ALOT louder, particularly with the big bore baffle. I know loud isn't everyone's cup-o-tea, but the bike just sounds great to me. Very deep sounding traditional "po-TA-to, po-TA-to" sound. Of course the sound is also driven by the hi-lift cam (.650) Woods 408-6.
I took the bike for a ride and it was so much stronger. The engine gained tremendously between 2-3000rpms and just seems to be able to whip through the entire rpm range at will. The ride was a very dramatic improvement and it's still running the map from the tune with the stock exhaust. The bike get's a new dyno tuning in Jan.
The install was very straight-forward and relatively easy. The only thing I found odd was the fact that all the hardware on the exhaust is SAE with the exception of the one bolt that's used to tighten the muffler to the headpipe. For some odd reason that bolt is metric. The chrome is very high quality and the fit is very precise. The exhaust header follows tightly to the frame of the bike for a very nice fit.
So let me know what you think after viewing the pics below. Here's some pics with the single 2:1 setup.
