When I bought my bike used back in 2010, the stock mufflers came with what I was told was Fullsac 2.25" baffles.

I wanted something louder, so I since put on Rinehart 4" mufflers, which come with 2.25" baffles. They are noticably louder for sure.

Because there is such a sound difference, I always wondered if the original owner was mistaken, and I really have the 2" baffles in them.

I assume the 2" references the ID or OD of the baffle pipe, which is visible sticking out from the inners of the stock mufflers. Is measuring the ID or OD the way to tell for sure which baffles are in there?

I figure if I really do have the 2", it would be worth putting in the Fullsac 2.25" in, which would likely sound the same as the Rineharts, then I could sell the Rineharts and come out ahead a bit. I actually prefer the look of the stock cans, mainly because the end caps screws are flush which looks cleaner than all these after market mufflers with their screw heads sticking up.

Actually after browsing around, I'm thinking the pipe that sticks out might be the same size on all the baffles- I would likely have to pull them out to measure the diameter by checking the other end of the baffle

I have had all three sizes the extensions are the same size as the baffle the 1 3/4 will slide inside the 2 in and the 2 in will fit inside the 2 1/4 I have a pair of 2 1/4 im trying to swap if you have 1 3/4 or 2 in let me know. Just measure the diam of your extensions.

Nope
see pics of 1 .75 and 2" cores.
I don't have the shot of the 2.5 cores, sold them before they were mounted.
 

[HOGMIKE]

2" core

[HOGMIKE]

1 3/4 and 2" cores
(different louvers on the 1 3/4")
Hope this helps a bit.

I've shelved the mufflers but I'll dig them out and since I believe they are only secured in with one screw, I may as well pull them out and see. If they are not 2.25", I'll swap you even trade- we can both pay our own shipping, and I have a US shipping address in Buffalo so it won't be much.

Let me see tmrw and I'll let you know.

But according to what Hogmike says, they are likely 2", since I recall measuring them awhile back. We'll see. Thanks to all for their input.

Sounds like a plan let me know

I pulled one baffle out (the other is stubborn- soaking in WD 40 for now), and the inside end is 2" (just a c-hair over  ).

So I guess I do have the 2"- makes sense by the way it sounded.

I emailed Steve inquiring about his new 2.25" SD cores, since in a previous thread he said they are even louder than the normal 2.25, since half the length is un-perforated. I also asked his opinion on wrap- I've been reading up on it, and kind of like the idea of the stove rope, since it probably won't muffle the sound as much as dyna mat.

I tried to attach pics, but my computer is slow and it's timing out.

Dartman, I sent you a PM.

Got it, If you want to experiment with the baffles you have, a piece of water heater vent pipe cut to length and a few clamps will almost mirror the SD design and increase the decibel level a bit.

[North Star]

Yeah, I don't want to get too much into experimenting with wrap- too many variables, and I can't be bothered installing/removing.

I'll try the 2.25 standard or SD's...just trying to decide between dynawrap, stove cord, or this wrap I read some guys are using from McMaster-Carr:

Waiting to hear what Steve recommends.

If I missed it
What are your goals?
Just wondering about the sizes of the baffles?
Or
Wanting "louder"??

I want pretty much the same sound from the Fullsac 2.25 as the Rineharts I have now. I don't like to leave parts sitting around, so ideally if the 2.25 gives me the same rumble as the Rineharts (a tad quieter while moving is ok), then I can sell the Rineharts and use the stock cans with the 2.25.

It would be difficult to have one system sound like another without a lot of trail and error IMO.
If you want Rinehart sound, keep them, if you want some other brand sound, use THEM.
Kinda like sayin "I want my Rineharts to sound like the Fullsac cores"!
As far as power differences, I think they'd be pretty close.
JMHO.
