I have a 2010 CVO Ultra and was thinking about upgrading the exhaust system. I found this thread about fullsac's from a year ago. Can anyone chime in with opinions after riding for a while with the fullsac cvo stage 1 setup. I see the power benefits are just about the same for both cores. I am curious about the sound difference between the 1.75 and 2.0 muffler cores?  I am leaning towards the 1.75 core because I don't want the sound to get annoying on long trips. Your opinions would be greatly appreciated. tks

I have the same bike you do...*S
I did the x pipe and 2.0 baffles with the Master Tune!!  You will Love it Best Bang for the Buck by Far!!
and you get to keep those nice muffler cans keeps the Stock look which I think is Great!!  I might do the Cams and head gasket, but to tell the truth it really runs Great with out them!!
I am sure that you will love it!!

Install is almost complete. I am up to loading the 1.75 map. I noticed after loading the map onto the ECM the file name was FP-2010-11-CVO110-Stg-I-XPipe-2.0.MT7 (74K). Steve is unavailable today so I was hoping someone that ordered the 1.75 cores for their bike could look to see what the file name of their map that Steve sent. Just want to make sure Steve sent me the correct map. I would think he would use 1.75 in the file name for 1.75 cores. Maybe it's the same map for the. 2.0. Thanks for your help.

If this is the map he sent you, it will probably be just fine, there is little difference between the muffler cores as far as flow. I would start with that map if you planned to go riding until next week when everyone gets back to work.

Mike,

Thanks for your response yesterday. Steve was also nice enough to respond over the weekend and confirm the 1.75 and 2.0 cores share the exact same map changes. Finishing up today and will take her out for a spin later. Can't wait

Enjoy the ride.

More power, better throttle response, less heat, better gas mileage and it will sound like a Harley.

Completed the install and map download yesterday.  Fullsac 110 Stage 1 is a wonderful product just as everyone says. Instant seat of the pants difference 
Also, unbelievable support from this forum.  Thanks to Steve & Alice from Fullsac and everyone on the forum that has helped me through the process. I highly recommend it as well.
