We have a pair of Screamin Eagle II's on the Sportster, and i am curious as to if the baffles in the muffler are removable. If they can't be removed...end of discussion. If they can be removed, will it hurt the engine because of too much backpressure, or will it just be too **** loud all together??

Mikey,
Removing the baffles will open up the flow through the mufflers and in turn reduce the back pressure not increase it. Typically a reduction in back pressure results in a reduction in the torque, especially in the lower RPM range.
Mikey, removing the baffles won't hurt anything. I had Screamin Eagle ll slip ons on my Deuce before I put on the Python Pipes. There's an idea. Get yourself some pipes with removeable baffles and then you'll have a choice.

I was told that the baffles on the SE II's were not removable at all. I read that they were packed with some kind of fiberglass and that that would need to be drilled/bored out... Then, I'm not sure what you would need to do with carb jetting/tuning???
betcha DJ knows????

Easy way to remove baffles from SE II slip ons:
Step 1 Unbolt SE slip ons.
Step 2 Discard slip ons and baffles all in one step.
Step 3 Find anything but SE slip ons to put back on.
Step 4 Have a beer and realize you have a real exhaust now. :bounce1:

Oh my god DJ... I pissed myself after reading your thread... it was very funny and very pi$$ poor of you... some of us were suckered into the SEII before we knew better... ok I suck I have a set too. Once I can afford either the bub stubbies or the V&H shorties I will try your baffle removal technique.
What about spark resistors? I've heard, not sure how true it is, that without baffles, sparks can come out of the exhaust and possibly start a grass fire in areas where dry enough.
Any opinions?

I've never personally had sparks come out my exhaust, except on a nitrous assisted engine where the sparks were lumps of carbon being superheated by the addition of N2O. However, I have had my jetting out far enough to have a 6 inch blue flame out the rear pipe on the dyno, kind of an afterburner look. :gasthrowe

Hey gixster,
A friend of mine just took the V&H shorts off his fatboy and put on a thunderheader. He has cut down the baffles. Are you interested in a used set? I believe he plans on listing them on ebay.
Send me a PM if you are interested and I will send you his email.
By the way he had no bottom end without the baffles and IMHO they sounded like poo. He put in a cam and added the Thunderheader and it now sounds ohh soo sweet.

I tried to talk him out of it but Jeremy sold him on it. I must admit, it does sound good.

I kind of thought mine sounded like a tractor, but to each his own.
I know seat of the pants and dyno numbers caused it to come off the bike real fast....

Now that explains it. I grew up in Indiana going to tractor pulls :theyareon
