RE: CVO factory exhaust
Well, I really like the sound and performance from the Rineharts. The stock exhaust on my 2007 SEUC was very quite and needed be opened up. I get way better performance now.
Good Luck,
Kevin

Stock exhaust are quiet and have to meet EPA guidelines thereforehave O2 sensors. The bikes run very lean and therefore very hot. I went with SEAC, True Duals and PCIII USB just topep it up and cool it down while hearing that true Harley sound. Motors are strong, just needs to breathe a bit more and get a little more fuel to smooth out the AF curve and cool things down some.

What exhaust comes on the CVO Ultras? I noticed alot of people change them out for a aftermarket pipe? Are the screaming eagles- not "SCREAMING" enough?

so therefore..........NO, the Screamin' Eagle models don't "scream" with a stock exhaust.[:'(]
I went with Rush slip ons with 2.25" baffles, NOW my bike SCREAMS!

RE: CVO factory exhaust
Exhaust discussions turn religious really quick.
Here is an OPINION - mine only.
The stock CVO exhausts are quiet especially at idle.
This is likely because they are tuned to run a little lean to meet EPA regulations -less pollution -better gas mileage.
But, if you get on the fuel with a good twist, there is plenty of sound.
The heating issue is true but can be dropped to a cooler temperature by changing your oil to a high grade synthetic like Mobil 1 or Amsol. The HD Syn3 doesn't do the job.
I didn't check the temperature change before I changed oils at 1000 miles but I would guess the drop in temperature was about 15 degrees farenheit coming off the engine. Mobil 1 is in all 3 holes.

"Exhaust discussions turn religious really quick."
Both are subjective and, as you said: opinion driven.
The CUSE2 & CUSE3 have catalyst mufflers running on the standard "Y" pipe crossover head pipes. They are similar to the 96" exhaust system in design but also have the O2 sensors and catalysts qualifying them for the EPA stamp of approval. Depending upon budget (and preference) there are many reasons to change them OR to leave them alone. As far as "Are the screaming eagles- not "SCREAMING" enough?" - in my opinion, NO. Neither in decibles or performance.
Mufflers can be changedwith no further modifications and gain a little of both . . .(volume and performance)
However, improving the fuel tables is necessary (SERT, PCIII, TMAX, etc) if the breather is modified for improved air flow. An excessive lean condition is created making fuel table & VE modification necessary.
Changing oil only yields little. Actually dumping the Syn3 is a good thing. But changing to fossil for break-in and then to a high quality oil is better.
