Default Stock exhaust 2-1-2 vs Screamin Eagle slip ons

I wanted to get some opinions and input from others here on this topic.

So, my plan in the short term (until a few years from now when I do a 1200 conversion and add an RB racing 2-1) was to just pop on the Screamin Eagle slip ons, some Xieds, and live happy with that for a while.

Today however, I was looking really closely at my exhaust and noticed that the stock mufflers have a tube that connects them, making them actually more like a 2-1-2 setup, than a true 2-2 setup.

From the looks of where that tube connects to both mufflers, it appears that I would lose this tube when swapping on the SE slip ons.

Is that correct?

And if so, has anyone done that install and noticed a drop in torque or power? (We are assuming no custom tuning here, or the lame factory map upgrade).

I'd like to hear from others who have swapped the stock mufflers for SE slip ons, if you lost torque, and if I am correct that the 2-1-2 setup becomes a 2-2 setup with the SE slip ons.

Thanks.

That tube does not make it a 2-1-2. It also has nothing to do with performance and everything to do with emissions and noise. IMO, you are not going to lose large quantities of torque by putting on some slip-on mufflers. The area under the curve may change a little and either smooth or move the torque, but not enough to ruin the feel of the bike.

I'm with you on the RB 2-1 and wanting something for sound until you can fully tune the bike. I was ready to go with some XIED's and Side Shots for a minute, but I have decided to wait until I can get the TTS Master Tune and the RB 2-1 sometime over the winter.

Either way you go, enjoy the ride.

Hmmm...I thought that tube allowed pressure to flow between the pipes, which would essentially make the setup a 2-1-2 right?

I guess that is academic if the SE slipons don't come with a loss of power/torque.

Anyone who actually did this swap, I'd love to hear your impressions also.

:-)

I did this...you use the factory cross pipe he is describing and do not need to do anything else. Remove the stockers, put the new SE spip ons on your bike. 30 minute project IF the stockers come off easily, but they likely won't. Anyway, mine are not the new slip-ons, but the old style race only application SE slip-ons. they are not EPA legal any more. They sound awesome (almost a loud as Rush or V&H slip-ons). I believe they have increased power and HP across the rpm range. I have no other mods, but going to put SE breather and X14iEDs on this winter. It will change your torque & HP curve slightly. Go for it.

I swaped my stock mufflers for the SE slip-ons. Like Sharkman said, 30 minute job...IF... the stock mufflers come off easily, which mine didn't. Still only took about 90 minutes. They bolt on exactly the same as the stock mufflers. I noticed no noticable change in performance but they sound a lot better, though not as loud as V&H, Cycleshack, et al. For the $170 I paid for them, I am pleased with the change.

Hope this helps.

Just put the SE Slip ons on my 2012 1200C. No loss of power or torque and they give you plenty of sound!
Penetrating oil for 30 minutes before the removal of the old (as suggested to me here) makes the job a lot easier.

Thanks guys, I think this is going to be a winter mod (unless I scrape up the cash before then).

I put the SE Slip Ons on my XL1200L at 1,000 miles. Seemed to lose performance and not much of a difference in sound.

Bought a pair of D&D Slip Ons and what a difference. Big increase in performance and very loud. Got a used pair on EBay for $99.

Really like the D&D's

I had SE slip ons when I bought my bike and were too quiet so I bought V&H shortshots like everyone else. I liked them but they were horrible on power after my motor work was done so I got a RB racing 2 into 1 and that got me 7 horse! I love the sound and it's nice and throaty!
