I went with Fullsac 2.25" baffles on my 2010 SEUC. After running with my new engine build I decided to go to a D&D Boss FatCat with a big bore baffle. While I liked the Fullsac approach I decided that to get the full performance out of my engine build, I needed to go to a 2:1. If anyone's interested, my 2.25" used Fullsac baffles (perfect condition) are for sale. New they go for $139 plus $20 shipping. Drop me a PM if you're interested.

...I still don't know which size baffle to get.  Seems like I read somewhere that the smaller (1.75 inch) baffle resulted in the most torque gain--is that right?

[GregKhougaz]

Fullsac posted that 2" produced most power though they were all very close. 

See here:  Muffler core Dyno Test! 2.25 vs 2.0 vs 1.75. Is bigger better?

Tons of stuff here to pour through but if you've still got doubts you ought to call Steve and ask him.

2in sound great but too loud for my ears on extended trips, I have both I use 1.75 most of the time. Depends on your riding style. 2 in have a nice deep sound but riding two up in the mountains they really hammer your ears on the upgrade.

I am debating between the 1.75 and 2 inch baffles.  I'm planning on running stock headers with cc.  I don't want a lot of noise, just a bit more rumble than stock.  Any advice would be appreciated.

Get both!
 
You can swap them out in about 3 minutes if you want quieter/louder!

Thank you to everyone who added info to this process. Here are my 2 cents and hopefully it will help the next person tackling this task. I used the Dremel #932 grinding stone as prescribed by the pros (got mine at Menards).  I used 4 of them (2 per pipe) and took my time on each muffler.  It took about 1 1/2 hours of grinding on the first muffler and 1 hour on the second one (two separate days).   I placed the muffler on a workbench with a trouble light above the work space. I layed the pipe in a feather bed like used in a baby crib and propped the pipe at an angle on a vise.  I used a Black&Decker RTX-B 3 speed rotary tool from Wal-Mart.  I swiveled it 90 degrees when grinding and that kept the knurled tightner from rubbing the end of the muffler.  I had no problem with the grinder after rotating it and it would grind flat with the Dremel bit that way. Recommend keeping the Dremel stone as straight/flat as possible when grinding to keep from grinding through the cover. You have to be patient as told in previous posts.  I blew up two of the grinding stones in the process.  Since I didn't need to save my old baffles, I hit them out with a 2" piece of solid steel rod.  It took several times back and forth with the bfh, bar and grinder process before each baffle broke loose.  Now I'm waiting for the 2" baffles to arrive in the mail and install them. Can't wait!

So, How does it sound without baffles?  We know you had a listen!

I have been looking all around this and other places to decide on what to get for a little more Tail pipe feedback, I must say it is quite exhausting!

I decided to go with the 2" baffles from Fullsac to begin with and possibly an X pipe in the future depending how I like what this gives me. Wish me luck with the grinder!

The sound/rumble/note is very nice with the 2" baffles, not too harsh and far from wimpy ... just shined up the chrome on the pipes with windex and did the final wrenching to ensure everything was tight again.    Prior to these I had Bassani 4" megaphones on it with Vance and Hines head pipes.  Kept the V & H head pipes with the CVO cans and Fullsac 2" Baffles.  The wife and me couldn't hold a conversation at stoplights with out yelling with the Bassanis even though they sounded really mean.  We now can listen to the radio, hold a conversation and when the throttle is snapped it snarls ... I love it!  Also put a HD Stage I Air cleaner on with a power commander and kept the stock air cleaner cover.  The bike looks totally stock.  It dyno'd at 92.3 hp with 113.31 torque.

Hi jim did you by any chance remove the insulation from your mufflers yet since youv'e put the fullsac baffels in if so how much difference did it make and is there any chance that the packing in the muffler will blow out the back
