I have the MO's and my buddy has the Rinehart slip ons. We both have '09 Street Glides. Originally his bike was louder and sounded better than mine. I added true duals now my bikes louder and he wants more volume from his.
My MO's have always looked better though! They definitely add to the look of the SG.

 

I have Rinehart Slip ons and my friends all complain about how loud they are. Then again I am alway ripping it in the higher RPM range.

 

Having just installed MO's on my RG, AND, having to endure the pain of following behind Rineharts more times than I care to remember, I can shed some true light on this as well. There are a handful of members in our club that have Rineharts (seemingly the bellybutton of slip-ons, everybody has them) and on a club ride. The position where you ride directly correlates to your arrival time at the meet-ups. Those things are frankly obnoxious to ride behind. Here is a good way to describe the sound, follow me on this. Think of true drag pipes from years past that a few morons still insist on riding on the street with. Have that loud crackly sound in your head yet? Now, turn the volume down about 30% and add a little bit of deep rumble. That's damn close. They sound meaty at very low rpm while in the saddle, but behind you is a different story and quickly gets loud & crackly (think drag pipes here) as the rpm's rise. It doesn't have to get to 4-5K rpm before the crackle starts either, a simple 2500-3500 rpm is enough to get ugly. Bottom line on Rineharts is, they are harsh loud and you won't be liked if you ride closely with friends. Small note; those black tips quickly fade to purple, so get the chrome if you choose these things.
The MO's? No comparison in terms of sound volume. WAY quieter than Rineharts, not even in the same league. Very mellow. Sounds like no other pipe, so a direct comparison is difficult at best. The sound? Do you have any old muscle car knowledge in your past? If so, think of a '68-'71 SS Chevelle 396/454. NOT with glasspacks (would be Rineharts if you were thinking that). Can you picture that sound? That's pretty much it. An omnidirectional bass tone with ZERO crackle or any high tones at all. To be honest, I didn't care for them moments after the install. I've since ridden at varying speeds listening with an objective ear and concluded that they are the perfect pipe for what they were intended for, namely, stereo friendly sound/tone that you can hear when you want and ride longer without that drone from louder pipes. But, if you want hey-I-need-attention sound, these won't do it. They're tame, almost to a fault if you're used to your bikes being a bit on the loud side. In closing, a rough guide might go like this; noise volume =
V&H MO's = low/medium
H-D Screamin Eagle = medium
Rinehart's = loud
Open drag pipes = very loud

Keeping in mind, pitch effects our perception of volume, so it's not just a dB thing. Choose wisely, good luck. And yes, the MO's aren't cheap.

 

i have the rinehart slip ons on my 08 streetglide, and couldn't be happier. the monster ovals look huge, and are likely very heavy. they also seem to stick out far enough to where they may drag when riding through some serious curves. i am probably wrong with the dragging issue, but would be concerned. the rineharts are plenty loud, and i always get compliments on the sound of my bike's sound. they have a deep thumping sound, and they do surely bark when you yank the chain. stereo friendly, and i just like the way they look too. rinehart a few years ago went to a hi temp coating on the black tips, verses the anodized black which would turn a copper color after a year or two. i would suggest going to a rally or event, and hear different mufflers, then decide. for me, i can't afford to experiment, so i just stick with the rineharts, and have had them on my past four harleys, including my current ride.

 

I like the Fullsac 2" baffles a bunch. I had Rush 2" with my stainless mesh and fiberglass wrap before the Fullsac. After the cam, the Rush really barked too much for me. the Fullsac is a full length non wrapped baffle replacing the stock insides. They are decent when cruising, bark when on it, and let the dyno numbers roll out. They are fairly quiet on a Stage 1 2009 bagger.

Thread hi-jack over. sorry.

 

Thanks Bagged Out and Butcher for your insight (and all others). This was the kind of input I was hoping to get. I think i'm leaning towards the Rineharts. Of course, I need to get a SG first to put them on.

Thanks a lot!

 

I went straight to the Rinehart TD's and havenot looked back. Nice deep rumble at idle and loud enough when on the throttle.
I have had VHMos on other bikes but have come back to my Rinehart TD's. It's like a golf putter, you try a few until you are happy with one.
I have tried several and came back to Rineharts. I also like the black tips for some reason.
Good luck and ridw safe

 

Got a Street Glide and ended up going with the Rineharts. Haven't had a chance to do much riding, but i'm happy with the pipes so far. Definatley no issues with hearing the radio. Thanks for all the advice.
