First of all, thanks to LarryB for turning me on to cvoharley.com! Wow, there's a lot of info here. I've been reading like a madman and I'm... well... overwhelmed? totally stoked? Grabbing my wallet? LOL!

So, even after a lot of reading here, I'm still a bit confused about the exhaust options on the '09 SERG. I want to keep my SERG so that I can easily return it to stock coniguration if I want/need to for whatever reason. Maybe that's a little irrational, but I've takent that approach with my non-CVO Harleys and it's become a "thing" with me. So, hear me out, if you don't mined. Ultimately, with the SERG, I'm trying to protect resale value in the long run, just in case.

It seems that a lot of folks here are drilling out the cat in the stock headers and replacing the cores in the stock slip-ons with the fullsac cores. I like what I'm hearing about the results -- sound, power, etc -- and I don't mind the work involved especially since LarryB has already done his bike and offered to help out with mine. However, this obviously compromises my ability to return to stock configuration.

Also, I'm a big fan of 2-1 pipes, having used them on both of my last two Road Glides. My '05 had a D&D FatCat, my '07  has a V&H ProPipe. I love the power you get out of a 2-1. I'm starting to be a little less enamored of the sound -- it's just too loud. Can't hear the radio. Can't talk to my girl behind me. My ears hurt after a long day's ride. FWIW, my '05 Road Glide originally had RH True Duals -- WAY too loud.

Of course, the problem with 2-1 on the SERG is the cutouts for the pipes at the rear. Somebody mentioned that D&D has a left-side falsie for the FatCat, but I've yet to find a FatCat for the 09s. D&D doesn't appear to have them on their website.

One of two people here have suggested getting a set of stock '09 headers to replace the CVO headers and eliminate the cat. Nota bad idea, just not sure where to find them.

I've also been looking at the V&H Power Duals, a 2-1-2 header pipe designed for '09 dressers. At ~$520 MSRP, they aren't cheap, but they look good and I like V&H products & V&H claims horsepower gains with this header (don't they all?)... Of course, that still leaves the issue of the mufflers.

In the end, perhaps I'm overly concerned about the "return to stock config" issue. If I drill the cat and replace the muffler cores with fullsacs, it's still the stock pipes, just with different innards. So, it LOOKS stock... is that good enough?

Sorry for all the rambling... I tend to do that...

Thanks!

I've got the 2009 SERG also. I've also got an 07 SEUC with D&D Fatcat 2:1. I like the exhaust, but, like you, I'm thinking I rather am enjoying the "quiet" sound on the RG. I'm seriously thinking of leaving everything alone. No ECM changes. No intake changes. No new pipes. If anything, maybe some SE slip ons. The bike feels smothered...no doubt. But, when I twist the throttle, it goes. Not the fastest bike out there...BUT..it's suiting my purpose...so far at least.

Ok OK I know....I've said I'm leaving it bone stock before. At least this time I'm not in a hurry to do anything.

Rick, Ive Drilled The Cat, really simple Mod by the way, and installed full sac baffles even easier, I have a set of takeoffs from an 07 SEUC with cats in the mufflers stashed away, If I ever need to pass an emissions test im covered.

Now that's a good idea.

RickC, 

          Congrats on the SERG.  I'm no mechanic but New Header Pipes from V&H:  $519.95  Monster Ovals $500 plus...... Install  $$$

          On the other hand:  Fullsac cores:  $109 (w/ CVO discount).  McGills core bit:  $26.  Hanging out with a buddy, drilling out the cat, grinding out the stock cores and installing Fullsacs:  Priceless!! (Less cost of a couple of beers).   There are great instructions posted here.  Result:  Great sound (not too loud but very deep sound), more responsive and cooler engine.  Seems like the best bet, esp. in locations where they enforce the exhaust regs. like here in CA.  Personally, I think the Stock head pipes and mufflers are beautiful.  Most aftermarket pipes are smaller and don't look right, esp. from behind.    There are Stock head pipes available on e bay and other places but don't get them from CA (with cat). 

Add the SERT & Heavy Breather:  Dynojet numbers:  89.07 hp and 109.22 torque.

Is this honstely the result of the 2009 SERG after having made these performance upgrades ?
I wonder and thought that there would be about 100 hp and about 150 torque

If you want these kinds of numbers out of 110ci, you will need much higher compression and head work on the SE110. Prolly, you'll need a bigger cam and maybe a throttle body, too. These numbers are possible, but the factory SE110 setup is tuned for EPA emissions, not extreme performance.

You'll blow a stock bottom apart with 150 ft-lbs!!!
