Pipes are D&D Fatcats with performance baffle which means they are loud, but baffle selection was based on dyno results and these baffles produced the best hp and torque numbers in the rpm range I ride in.
The D&D Fatcat has an excellent reputation for producing power and torque where you want it. However, the new 2:1:2 systems are pretty good too. If I had a new bike, I think I'd go with cat less head pipes and baffle inserts for the stock cans. Full sac is a reputable supplier of such parts. Good luck with your selection.
I agree the Fullsac 2-1-2 pipes are excellent performers... I had them on the Honey Badger for about 9 months before I decided to go with the Drago's 2-1, and many of my friends run the Fullsac system. But in my mind, nothing beats a 2-1 system for total performance. I found that my Drago's 2-1 needed longer-duration cams than the Andrews 54H cams that performed so well with the Fullsac system. But longer-duration cams tend to move the torque curve to the right, which people who like a lot of low-RPM torque don't like.
Also, 2-1 pipes are more difficult to tune with, because they have an inherent dip in the VE tables that I call "the lake" since it shows up in blue in the VE table charts in MasterTune. My dip is most pronounced around 2000 RPM to about 2750 RPM, in the 40-60 kPa range. We encountered it when tuning the HB, and it's even shown in the TTS tuning guide. Mr. Wizard was able to bring it up some with EGR manipulation and who-knows-what else he did. He won't let me talk to him while he's doing his "wizard" thing! New timing tables from the TTS cal for a "race pipe" and SE 260 cams (can't remember the cal number) helped a bunch too, and transformed "the lake" into more of "the swamp"... not quite so blue!
I can't wait for the new TTS Timing Assist support to become available, so we can get the timing tables dialed in even better.
