 Thx HogMike...Top portion of the floor jack handle did the trick. Both pipes are ready for new baffles. Will order the 2" baffles this weekend.

You didn't have the cores already??
Tech tip:
If you have access to a Whitney punch, use that to punch the holes in the chrome pipes, follow the directions to leave them a little loose fit at the inlet (room for expansion).

Didn't want to order them till I had the old ones out and was sure I still had a good set of pipes.

Great thread guys. So great in fact that I am ready to move forward with this on my 2011 CVO Ultra. The ONLY thing holding me back is not being able to hear what the catless stock header pipe and any of the Fullsac baffles sound like. Is there anyone with this configuration within a 100 mile radius of Northern Virginia that I can hook up with to hear this?

My computer speakers just will not cut it.

Update:  Finally got the baffles installed and the pipes on the bike tonight.  What a nice pleasant throaty sound. I believe the Pythons were alot more restrictive than I thought. You can't see a bit of light when looking through them. I wish I understood muffler accoustics better. You can see clear through the stock pipes now with the fullsac and the bike is much more easier on the ears compared the the Pythons.

My tune must not be too far off. Took if for a spin, no intake or exhaust sputtering on accel or decels. Got on it hard and she pulled real hard...no flat spots noticed by the seat of the pants. Taking it to the Blue Ridge parkway this weekend with the wife. Can't wait to see how she does on the road with temps in the high 90's and dewpoints in the 70 range.

Another trick to keep the drill bit from walking when drilling the 1/4" hole. Put a piece of duct tape on the area your going to drill. Measure the 1.5", mark and punch it (on the tape) and drill. No bit walking at all. I first used a smaller bit and then went to the 1/4.

Z10, sounds like you're a happy camper now.

I did the same thing to my '09 SERG and did the work on my full lift.  Drilling holes on round hard surfaces can be tricky.

I have a few of the spring loaded center punches that Harbor Freight sells.  I have their small light duty and the heavier duty model as well.  With the heavy duty center punch you can actually place a prick punch divot in the muffler that makes it very easy for a 1/16" drill bit to follow without walking off center.  I always pre-drill and the follow up with the true size I need.  I've ruined a few parts in the learning process, but pre-drilling in my older age has proved to safe time and money.

I have the Fullsac 2" baffles with the stock HD packing.  They bark when needed, but can quiet down on the open road to talk and hear my tunes.  Very nice compromise between stock and drag pipes.  On my last '08 SERK I had the V&H Ovals and they were a bit loud and it was hard to talk while riding.  The 2" were a welcomed relief.

Thanks for your review of the new exhaust additions.

Just finished the full sack upgrade. Thanks Jim you made it rather simple...Tom

I just pulled my 1+3/4" fullsacs and replaced them with 2".  Really....not much difference on sound.  Maybe slightly deeper.  Anyway, I have a pair of 1+3/4" for sale.  Only 5,000miles on them.  A little dirty, but cheap.  I'd take $75 for the pair, including stateside UPS if anyone' interested.  I'll be gone for about 10 days, so be patient.  I'll check the site for any interest.

Resbiker ............do you still have those Fullsac 1.75" cores for sale? Just installed the Stage I with 2" cores and am really happy with reduction in heat and seat of pants power increase! The sound however, is a bit more than I'd want to listen on an all day ride .............I'm particularly looking at options for softening that hammering sound when going through the gears and/or riding uphill. Tomorrow, I'll replace the fiberglass  packing with TechMat to see if any improvement with acoustics. If that's not the answer, perhaps the 175"? Different strokes for different folks ..........natch .......... at one time, Steve@Fullsac loved the 2"ers, but was reportedly using the 175"'s for longer rides.
Many mahalo's to Jim for his most excellent instructional guide!

I just finished installing 2" in 11 CVO mufflers. This post was very valuable!!!

So how is the sound? I am fixing to do this mod and need advice on which size to go with

[whozathd]

Just wondering did you ever go the fullsac on your bike and if so, which one?

yes i did.. easy mod to do. took about 15 mins max to cut the old baffles out. i installed the new 2" fulsac baffles with the white packing that came out with the original baffles. i wanted something a little louder but not to loud as i pull a trailer and the last bike i had had rhinehart 3 1/2 " and it was way to loud with the trailer on the hyway. well after a short ride the new baffles came back out and went back in without the packing, damn near sounded stock with the packing. now it has a louder sound but not to loud so i think it is going to be good with the trailer. i don't think that is as loud as a friends that has 4" rhineharts but it is louder and has a decent sound i think so far. i am going to have a friend ride it soon so i can hear it not riding bike. i had no problems removing the old or drilling for the new and the new ones slid right in twice  now with no problems. i do wonder in my head how the 2.25 would sound and some day might get them to see and swap out for trips.
i also put on a catless coated head pipe from fuel moto

Many thanks for all the info in this thread!   I'm considering many different setup's at this moment, but leaning most recently towards the Vance and Hines Power duals head pipes and the CFR (Cary Faas Racing) mufflers and the SERT for turning on the 2012 CVO Ultra.   With the sound bites I've found those sound pretty hot and not everyone has them.   Anyone heard this setup by chance?   IF so - thoughts you care to share?  Thanks!
