Removing baffles from new Screamin Eagle Slip-Ons
I have an '07 Fat Boy with the new Screamin Eagle Slip-Ons. As everyone knows, these pipes are considerably quieter that the old SE IIs which I had on my '00 Fay Boy. In examining the mufflers there appears to be a Torx-head bolt on the front and rear of each muffler. I am assuming removing these will allow the baffle to slip out. I'd like to know if anyone can identify what type if Torx I need to remove the baffles (it is a captive Torx).
My understanding is that the new SE baffles for 2007 are packed in fiberglass or some other heat resistant material. I'm assuming if I removed the packing material the sound quality would be better and would not necessarily change the performance characteristics of the engine. Has anyone done this, or have an opinion?
Thank you in advance,
Rick

hmmm, my input,,when I got my loud pipe ticket,,
leo said if baffels are removable they are in violation
if thats the case how could new SE's be 50 state legal?

SE's(07) have baffles.....
And they are coated with a Catylitic Compound (Epoxy), vice using a solid core cat.....
Heck, my SE II's have baffles (BCT's), but they are baffles......

RE: Removing baffles from new Screamin Eagle Slip-Ons
I have removed the baffles from my 07 SE slip ons.I removed the torque screws and then needed to hammer the baffles out with a dowel. They are wrapped in fiberglass. As far as their configuration, it appears as if they took a typical perforated baffle and modified it. It looks like they made a cut towards the inlet of the baffle and then bent the cut portion such that it completely closes off the baffle, forcing all of the exhaust gases to go through the packing, out the perforations, and finally out the end of the pipe.
I cut a hole in the part of the baffle that is bent so that some exhaust can travel directly out the pipe. I also left the fiberglass wrapped around the baffle. They do sound louder now that I cut the whole, butI doubtthey're SEII loud. In hindsight, I should have just tried to bend the cut portion back up, leaving more like a typical baffle.

I just took the torx bit, put it into a socket (1/4" i believe) and attachedthe socket to a wrench.

RE: Removing baffles from new Screamin Eagle Slip-Ons
I removed the baffles from my 2007 SE's. I took out the fiberglass packing and reinstalled the baffles. The baffles were pretty tough to get out. I used a dowel just barely smaller than the opening at the headpipe end of the muffler. The sound is quite a bit louder and a little deeper than before. I went out for a short (<10 mi) ride. I really didn't notice any change in performance. BTW- this is on a stock (besides the slip-ons) 2007 Street Bob that has had the factory recall (torque calibration) flash. If anyone thinks this willcause problems, please let me know. I don't think it's running any leaner thanbefore.
Here are some pics of the baffles and the packing. (
Not sure if the pics will work, I haven't done this before.) -Z

RE: Removing baffles from new Screamin Eagle Slip-Ons
Thanks for posting those pics zmeister.
Thats just what I wanted to see. I was thinking about taking the baffles out and drilling larger holes or maybe even adding another row or two to get a little more sound and leave the packing in place. After seeing the pics, I'm not so sure thats what I want to do now.
