Screamin Eagle II Muffler Part Number
#11
Only from what I've read , but I have never had a decell pop or bang with the SEll style baffle in any muffler.
The mufflers with a straight through core , whether perforated or louvered , seem to have a decell pop problem that the more redirected cores don't have.
As an experiment , I tried the SEll's with stock air cleaner and no tuner , no decell pop.
Next I tried adding the Screamin' Eagle Air filter setup (hamcan style) with no tuner , still no decell pop.
I have a tuner now , and as of yet never had a decell pop , and still don't.
I can only surmise the exhaust pulse cannot re-enter quick enough through a redirected bafle to produce the dreaded decell pop.
I don't have a decent video rig to post a quality enough video to actually hear them properly.
There are a few on youtube that are pretty good , make sure you listen to a 1200 , they are louder because of the increased volume of air.
This was one of the better videos I found , it doesn't really capture the sound intensity though.
They're not bad out in the open , but get near a concrete wall or car on the right side of you and they really bark.

No big deal either way. Very good info. Thanks.

Good to know. I guess my memory sucks and I'm completely wrong. I should have looked and double checked. Thanks for the correction. My original post has been edited to state the correct info.

The OD is 3" on my 80424-04 mufflers.
At the bottom of this page shows what the SEll baffle looks like.

The V-Twin mufflers state that they have packing , they would probably be perf tube style , not redirected like the SEll's.
Cycle Shack shows a baffle for late model SE mufflers that look very much like the SEll baffle design.
I'm thinking Cycle Shacks might be a closer match to the SEll style baffles than the V-Twin MFG.

I'm having a tough time finding a picture of the baffles that come stock in the MXL-130SS mufflers from Cycle Shack... where did you see a picture of a similar muffler?

Here's a pic of the replacement baffle for a MXL-130SS
https://www.denniskirk.com/cycle-sha...prd/H44905.sku
The MXL-130SS is a 2 1/2" side slash slip on setup.
They sure look like the SEll style baffle.
I found through further checking that the 3" series , such as the MXL-330 uses a glass wrapped louvered core instead of the mechanical baffle.
I thought they were all mechanical baffle , but the 3" are not , my mistake.
Cycle shack does make a replacement baffle for late model Screamin' Eagle mufflers that is about a dead ringer for the SEll mufflers if you need more tone from them.
https://www.denniskirk.com/cycle-sha...rd/4403296.sku
These fit the 80205-07 , later model Screamin' Eagle mufflers.
That might clear things up a bit.

No worries. I only noticed it because I just (Monday) swapped out my SE street legals for 3" Cobra slip-ons.

Just to give an update... I was leaning towards the Cycle Shack MXL-130SS mufflers but just did a last minute decision change for the V-Twin 80424-04 mufflers. My main reason for going for the V-Twin... aka Wyatt Gatling?... was that these are 3" mufflers, which I think look more proportionally correct than the 2.5" Cycle Shacks. Both seem to have a tone I would like, but the V-Twins sound more like the SE II's I used to have and love. I just hope the balonga cut looks as good as it did on the '98-'03 version. I never recalled being able to see the baffles inside the SE II's... they look more visible on the V-Twin's, so I'm wondering if that will look a little odd. I almost want to get both, just in case.
