Elginator,
I just put a set of V&H slipons with the quiet baffles on my bike this weekend. Like you, all I wanted is a better sound but not a lot louder than stock. I called Vance & Hines and asked them how loud their mufflers are compared to the other choices and here is what they told me.
Stock mufflers = 81 db
Old Style SE II = 110 db
V&H Slipons = 100 db
V&H Slipons w/quiet baffles = 96 db
Keep in mind that an increase of 3db is a doubling of noise. The V&H Slipons w/quiet baffles are 5 times louder than the stock pipes.
FWIW I wanted a slightly throatier sound than the stock pipes on my 2004 FXDX. Iwas advised to buyHD's "Torque Mufflers", for me way to loud so I sold them.Next I bought HD 49 state legal mufflers. But when I got them home and opened the box there was a set of used SE2 mufflers in it! For the hell of it Iinstalled them and started the bike. Again too loud and raspy. The dealer didn't have another set of the real 49 state HD mufflers so he refunded my money and let me keep them. Maybe I can make a pair of lamps with them?
Anyway Ifinaly did getthe HD 49 state legal slip-ons. They areslightly larger in diameter than the stock mufflers. This larger sizeand being slightly less restrictive allows them to flow better. And they sound just a little louder and deeper than the stock ones.
Stock mufflers = 81 db
Old Style SE II = 110 db
V&H Slipons = 100 db
V&H Slipons w/quiet baffles = 96 db
I guess these numbers are reliable since they came from V&H's and not HD. But, there is obviously a difference in what the sound meters pick up and what the human ear hears. Because, I've had the old style SE II's and there's NO WAY they are louder than V&H Straightshot slipons which is what I have now. I've had people notice I changed my mufflers without knowing or seeing them first and all have commented how much louder and better they sound than what I had before. I liked the SE II's and I think they are comparable to what the poster is looking for here. But, I love my V&H's and they are, at least perceivably, louder than the SE II's.

I had not heard that the decibel scale is nonlinear. But does that mean the Old Style SE II are nearly 10 times louder? I guess it could, now that you mention it.
I'm not clear about which HD slip-ons you mean. Do you have the item number or the harley description?

You'll drive yourself nuts trying to relate to that decibel science stuff. I went through the same discussions on another forum when I was looking for a quiet generator for RVing. The SE II's are louder than stock and produce a nice rumble but are not that loud - trust me. I had some for a year and know several others that still run them. They sound good but are not loud by any stretch - at least not out of the box.
I don't havea decibel meter but I have a very good ear when it comes to Harley's and pipes. Based on the numbers provided, my old SE II's should have blown my ears off compared to my new V&H's slipons and, I assure you, it's quite the opposite. And, I'm not an isolated case. I know several people that run SE II's and they all sound about the same.
The HD's he's talking about are the newer SE's that are legal in 49 states and are better performing than stock mufflers but hardly any louder at all.
I also did the SE11 pipe and want less sound and went back to stock pipes with the center plug knock out. It is more noise than stock pipes and less sound than SE 11 pipes.
I'm about to buy a set of PeaceMaker Exhaust pipes. It's the one that lets you switch from baffled to no baffles at the flick of a switch. It helpskeep the neighbors happy. I leave for work at 6am and want to let the neighbors sleep. Once I'm on the road I can open them up and let her talk. Also, if you roll up on a cop you can switch it to baffled and they can't ticket you for loud pipes. They are a couple of hundred more than a regular set of pipes but I think it will be worth it.
I spent the last 4 months with this same dilemma! The stock pipes on my 07 FXDC were way to quiet! When you can hear the engine pistons and crank case sound over the exhaust on a Harley there is a problem!!!
I bought some Rush 1.75” slip-ons and big difference, too much of a difference! They sound great but way to loud! I then bought 1.5” baffles and wrapped them in extra fiberglass and placed them into the Rush slip-ons. A little quieter but way to loud when I would crack the throttle!
Put the stock slip-ons back on and felt like I was on a moped once again!
A few weeks ago I bought a set of slightly used SE II slip-ons off ebay and am very happy with the sound! Nice low rumble and not too loud just about right! I would recommend the SE II! You can find them on ebay for less than $100!
I guess I have sensitive ears also!
I thought about the peacemakers myself but they are not very cheap.
