I also went with Rinehart true duals, love em.

 

true duals sound awesome i have the fullsac a buddy of mine has the vh pipes

they sound great he also has duals the look good to-ride safe

 

I just installed V&H Big Shot Duals on my 08 Street Glide and I am very happy with the way they look and sound. They are essentially straight pipes; my wife’s reaction was, “that’s too loud but I like it.” I have a white bike and went with the pipes with the black heat shields.

I was surprised at the reduction in heat hitting my thighs, even when I was cruising Duval Street in Key West on an 80° afternoon.

They come with openings for the O2 sensors, you will need to order plugs if you are using a Power Commander.

 

I'm a dealer and have sold a ton of the Rhinehardts(nice pipe), actually I have them on my 2007 Bagger. However in my opinion the Bassanni Tru Duals have them beat. With the megaphone mufflers, which are not really like a medaphone. I think I have a taker for my Rhinehardts and I'll be switching over.

 

For what it's worth: I've got Rineharts on my '06 SG and put V&H TD's w/ fishtails on the wife's '07 Heritage. Both sound great and make more power everywhere with NO loss in low end. I'd also check out the Bassani setup - heard one and really liked it. All three make excellent 2-1's if you like those also. The V&H Propipe probably coming out as best bang for the buck.

 

Keep in mind that the Rinehart TD system has a 2 inch inlet at the headpipe. So once you go with the Rinehart TD's, your options are very limited if you should ever decide to change mufflers. I'm fairly certain that Rush is the only outfit that makes a HD Touring slip-on with a 2 inch inlet.

I believe the VH dual headpipes are 1 3/4 so you could use almost ANY slip-on muffler available, including Rineharts. As far a sound goes, you might consider Rush in that their mufflers have 5 choices for baffles and lots of tip options.

My opinion on the TD's in general is that they are worth it for the looks, the sound, easier maintenance / cleaning and elimination of the heat issue. I don't notice much loss of low end torque. If any, it's a fair trade-off for the benefits.

 

I installed the V&H Ovals on my '08 RK and rode it for a couple thousand miles then I installed the V&H true dual head pipes. The sound improved greatly - deeper, not as crackly and more separated (if you know what I mean).

By the way, don't worry about any loss of low end torque, you don't lose any noticeable low end torque (You should notice a gain from the freer flowing exhaust), however, you may not gain as much as with a 2-into-1 pipe. You'll only know this by putting it on a dyno and comparing them back to back after tuning. A good tuner will help you get the most bang for your buck throughout the torque curve and you will not notice any loss using the seat of the pants method of testing.

 

Lot's of good opinions on here, but I'd like to add my two cents, if I may.

Performance: I worried for a while over the Rinehart true Duals I picked up at a V-Twin show for my 07 SG. I wanted more low end torque and I'd read on here, in fact that a true dual header system will decrease back preasure, which in turn decreases low end torque. That is a true statement. I was very much needing an increase in low end torque and wasn't going to put them on, if that was the case. I called a Bub tech and got more info on their design and numbers. I found that the Rinehart True Duals are not really a true header design, in where the pipe is wide open all the way back. This would in fact lead to a reduction in low end torque. The Rineharts are gradual and staged, if you will, in where the pipes start out at a smaller diameter at the head end and gradually, in stages, get bigger towards the muffler. This staging creates the necessary back preasure that's needed to keep or enhance the low end torque that we all love and need. I had heard that I'd pick up around 5 to 8 foot pounds of low end torque and can validate that with the seat of my pants. The bike responded much better off a dead stop, riding two up, where it had stuttered before. I loved the power and torque increase, not to mention the sound.

Sound: My opinion of the sound is that the Rineharts offer a crisp, race car sound. It was almost too loud, since I had a stereo, but found myself constantly smiling at what I was hearing. Not too deep, not mushy or muffled. Just right. At 4000 rpm it really shined. What I've noticed from some of the V&H's mufflers and pipes is that it's not quite as loud, but is a little deeper and not quite as crisp sounding.

Keep in mind, adding just muffler slip on's doesn't really change performance much per say. My experience included a HD Screaming Eagle Air Kit and a Power Commander, which was the easy part of the installation. And btw, the power Commander comes with the sensor plugs, so no need to buy them, if you go that way. The stock, supplied map rfom Dyna Tech seemed to run, respond very well, but I can't verufy air to fuel ratios, since it didn't see a dyno.

As for the 09's, I'm not sure that I'd want to replace that system just yet. I really like the fact that the Moto Co. used a 2 into 1 into 2, since that gives us good back preasure for torque and lets us play around with slip on's. I also think it's a thick and good looking header system. I'd say a set of slip on's, air kit of your choice and a PCIII and you should have all you need for power, torque and the ears to hear.

Take care guys and God Bless,
Ty

 

Not trying to turn this into a battle here, I'm just trying to show that low end torque is not "decreased" with dual exhaust of good design (Rinehart, V&H, others...) - maybe not gained as much as it could be, but not lost.

Here is my dyno sheet for the V&H Ovals and true dual head pipes. Note the increased low end torque over stock. BTW, the lower line only represents my baseline attempt at tuning before it went to the dyno, not baseline HP and torque which are significantly lower.

Others with duals may show higher or lower torque but I'll bet (unless they are badly tuned) they are all more than stock. And as I said in my post above, if you compare a properly tuned bike with duals and properly tuned bike with 2-into-1 exhaust I doubt you will notice a difference using the seat of your pants method.

 

just pull out the V&H baffles and cut them in half. If you want to waste more money then do something else.
