[Mr. Warlock]

For those who have tried both.....

What is the difference in noise levels from the 2.0 Baffles to the 1.75 Baffles?
I have had the 2.0 and contemplating the 1.75.

Thanks!!

I'm not sure that anybody telling you the difference in noise is going to help you. Use the search function. Some years ago fullsac did post horsepower and decimal comparisons, if I recall. A couple of members also posted YouTube videos showing comparisons.

[Mr. Warlock]

Question still stands. My question is for anyone that has tried both.

I already tried the search function Greg. If I would have found the answer that I was looking for I wouldn't have asked.

Must notta tried very hard (just kidding... )  Some good information on sound levels, comparing to 1.75/2.0/2.25 baffle sizes but some of the answers are deep in the body of the posts.

Here's someone that sold their system because the 1.75 and 2.0 were too loud

I used the search criteria on the home page of Fulsac 1.75 baffles and Fulsac 1.75 vs 2.0 baffles


Lot's of sounds on YouTube, too, using search criteria "fulsac 1.75 vs 2.0 baffles".  A few examples

[Ironhorse]

Yes, I have tried both on my old 2001 Ultra. I found the 2.0 to be louder, and the 1.75 to give more torque. No dyno testing to show on paper, just a seat of the pants feel. I stuck with the 1.75 as it was not as loud.

I went with the 2.25" with tune, don't see any difference in seat of the pants from stock. Nice sound, not to load IMO.

Yes, I have tried both on 4 different bikes.
Yes there is a difference in "noise" levels.
Yes I have tried variations on the 1.75 cores and there is a slight difference in sound/frequency depending of either stock, modified, etc, etc

I guess it's what you are "contemplating" going to the 1.75?
Are your concerns "noise", "power", "driveability"??

There has been much testing on the Fullsac cores over the years and a call to Steve may be what you need to do.
He may ask a WHOLE bunch of questions to try to fit the cores to what you want. The nice thing I have found out is that I have 3 bikes with the cvo mufflers and different cores I can change easily.
Maybe if we had a little more info about your riding style, and what your goals are we can help a little.

Thanks for the replies, I guess I asked incorrectly. I found pretty much everything that you posted Haird but I wanted to get a personal feel from those that have actually tried both.

Thanks again!

Have had both, and prefer the 1.75.  The smaller baffle made it easier enjoy the stereo and to cruise locally. I came to the conclusion that the smaller outlet was loud enough to let you know you're on a Harley and still enjoy the ride.

[Chief2505]

I wonder if that guy ever sold that set up and would it fit my 16 CVO limited?

[TNCarters]

I have run both 1.75 and 2.0 on my 2015 CVO which has a FuelMoto head pipe.  I like the idle and acceleration sound of the 2.0 baffle better but my old ears like the 1.75 baffle when touring.  Wife (passenger) prefers the 1.75 as well so that is usually whats in the bike.  I do think my 2 year old stock muffler packing is about gone so that could make both a bit louder.

I started with the 2.25 and liked the sound but the drone at cruise caused me to wear ear plug on long trips.

Got tired of the ear plugs so I installed the 2" baffles which did soften the drone at cruise. Idle and acceleration noise/tone seemed the same the as the 2.25....but was probability a little softer.

However, the 2" baffles eventually caused me to wear ear plug again.

So I installed the 1.75 which were perfect at cruise but idle/acceleration was a lot softer.

I then installed a 2" baffle in the left muffler and kept the 1.75 in the right.  This seemed to increase the idle and acceleration a touch and kept the cruise drone at a nice level.

So far I pleased with this setup.

Hope this helps.

Stock or aftermarket headpipe?

[HOGMIKE]

Stock or aftermarket headpipe?

You do make a valid point about the header.
I HAVE noticed that the sound will change depending on the header being an "x" configuration and also depending on the packing material (assuming stock CVO cans).
I have tried various combinations of core size and length, packing, stock screens to keep the gap between the screens and the core.
I have found the combination that works very well for ME.
I like my tunes, don't like the droning sound when pulling my trailer, etc. etc.
My setup won't work for everyone, but I've been satisfied for many years with the complete system from Fullsac.
"System" is the key here IMHO

[dknuttgen]

I am interested in getting those 2.0s from you if you decide to change and want to sell them. I removed the cores from my stock mufflers and need to put something back in till I can do a complete fullsac system.
Thanks!
