The 50-State-Legal SE slip ons look good and -- That's about it. The 49-State-Legal SEs are a little better (if they still make 'em. dunno).

My understanding of all this is -- The Stage I is about as useless as a screen door on a submarine. If I want to do an air cleaner and exhaust, my Dealer won't even do the Stage I. Claims it just simply sucks and they don't want the 'come-backs' on it.

I have the V&H twin slash slip-ons with the standard baffles and they're fairly loud. Not obnoxious, but most assuredly noticeable. I heard some with the 'quiet' baffles and they still noticeable, but not what I would call loud.

I haven't done anything to tune my bike yet and with just the exhaust, it seems to be doing okay. I will do a tuner in the future but not until the bike has some mileage on it. And that might be a little while. The weather down here, in SW Florida is just hotter than a hooker in Church right now. By 8:00AM, sweating your nutz off. I'm serious.

As far as the SERT, if you're going with the SE air cleaner and slip-ons, the SERT should have that MAP dead-nuts, right on the money. They are Harley parts, afterall. If you decide to use another manufacturers exhaust or another air cleaner, that's when they might have to dyno it. MIGHT being the operative word here. Even then, they can get pretty close without a dyno as a rule. Sometimes. Sometimes not.

But if the dyno is part of the deal, just make sure you're getting what you want in the first place. If they're using SE parts and 'throwing in' a free dyno? I dunno.

 

What is an "indy" dealer?



Pretty much what I'm looking for, I'm not looking to make 100 hp. I was just wondering what the gains would be in the real world.


I really need an education on these new injected bikes, i have no idea what you guys are talking about when you start throwing out the "sert" and "tts" and "indy" stuff.


Thanks again guys, you are helping a lot.

 

indy = independent shop, privately owned, not associated with a corporation.

 

SERT is what you're getting (Screamin Eagle Race Tuner). A lot of guys here swear by the TTS. I'm not familiar with it and have no opinion one way or the other.

But I think it's for serious power-adders. From what I understand, the SERT has a couple down sides, one being that it's permanent and can't be moved from bike to bike. For some that might be important. For me, I couldn't care less.

Another is that every time you add or change something you have to have it dyno-ed again. Again, for me? I couldn't care less.

Once I get my bike to where I want it, I'm done with the power dealio. Not interested in drag racing Hayabusas. At all. (you're gonna lose anyway, so what's the point?)

I (personally) have a couple problems with what your dealer is doing. (not you, your dealer) Now, don't take this wrong way but (I hate those, except for Ghostrider's avatar).......

Are you CERTAIN you're gonna be happy with the sound of the SE slip-ons? Do they have the catalytic converters in them (which chokes the engine, IMHO)? Are the mufflers you're getting legal in Californis? If so, I'd look into what's in them. Kalifornia requires some seriously weird **** even in Harley mufflers.

Another thing. Your dealer sez he's giving you a 'free' dyno tune? For Harley parts? For a Harley Air Cleaner and Harley mufflers? That download should be a slam-dunk, ready to roll, pre-determined MAP right from Harley-Davidson.

To me, your dealer is giving away ice in the Winter. A 'free' dyno? On ALL Harley add-ons? And that dyno is valued from between $150 and $300 depending on your dealer.

Now, if it's a 'done-deal' don't worry about it. If it was 'free' and the papers are signed and sealed? Don't second-guess yourself. You can go crazy trying to figure out what's best for you and your new Harley. Trust me, I know. I've only had mine a few months and I've got several hundred dollars of new parts laying around that I bought and didn't like -- Already. My neighbor probably has a couple thousand.

Neither one of us is gonna sell them. We both are of the opinion that we just might need them some day. Yeah, right.

Back to you. It doesn't hurt to ask a couple questions of your dealer. The only dumb question is the one you don't ask, remember?

And don't let my (and others) skepticism ruin your 'experience'. It comes with the territory. Enjoy your new motorsickle and good luck.

 

What you are planning to do is exactly what I did to my 2009 FXDC. I bought a set of SE slip-ons on ebay for a 2006 which still have removable baffles and altered them slightly to get a little more sound. I didn't want loud but a little more sound. After adding the SE air filter and having the H-D remap there was a very noticable difference in performance. The HP an TQ chart from a previous post is the one Harley puts out and from my experence it is probably reasonable. These are the only performance upgrades I plan to do so I didn't need a more expensive programmer. I didn't buy the Harley as a performance bike. If I wanted a fast bike I would have purchased a Kawasaki 1400 for less then I paid for the Harley but I don't think I need or want to go 200mph.

 

So lests just say that once the work is done and I'm not happy with the sound of the exhast, could I just mess with the baffels and not have to retune the bike? All I really want from the exhaust is to be able to hear my engine at 65 mph!

 

Not to be a complete smart a$$ but IF thats all you want, change helmets. Honestly I have 4 helmets & 2 of them you don't hear a damn thing. My daily helmet ( around town) I can hear everything.

As for all the Cal comments yes... there is some wonky stuff done to the bike.

Best of luck.

 

Big,

I have the SE slip ons and the SE stage AC, with a PCV. I have absolutely no problems hearing my bike at 65 mph. The SE pipes ,from my experience will open up after a few hundred miles also.

Hey man, I have the 49-state SE Slip-Ons, the SE A/C (not the heavy breather), and the H-D download on my 2009 FXDC. The SE Slip-Ons are a little louder than the stock pipes, but still below 80db. I think they have more bass that the stock pipes. The sound seems to travel farther. They sound good to me, without being too loud. (I'm 55, and I have hearing issues, so I don't want obnoxiously loud pipes.) The download, remapping the ECM, worked great for me. The quality of all of these parts is high. I like my set-up.

I've read the SEST user manual. It looks like a good product for fine-tuning the ECM. The auto-tune feature seems to work well. You don't have to haul around a laptop on your bike to use the auto-tune feature -- a plus in my book. The SEST might not be transferrable to another bike, but if you make other performance mods to your bike, you'll be able to use the SEST to retune the ECM.

Independent published accounts of performance improvements with this set-up measured a 10% gain in HP and torque. I definitely noticed better trottle response after I made these mods. It's more fun to ride now. I believe the bike runs cooler, even with just the download. I measured cylinder head temperature before and after with my infra-red thermometer and saw a 30 degree temperature reduction.

Net / net, it's all good. Study up on the SEST at your leisure. The main thing is enjoy riding that bike!

 

I'm in Iowa, we don't have a helmet law so that wont help cuz I don't wear a helmet.
