Does anyone happen to know the part number of the old style Screamin Eagle II's that would fit an '08 Nightster?

 

I have these pipes on my bike. Not sure if this is what you're looking for. I don't even know if they're Screamin Eagle?? There is no mention of the name except SE. Maybe someone can let me know...?

 

I think these are the ones. I had them on my '02 883 and they said Screaming Eagle II on the mufflers themselves, facing outward when installed. Yours don't say that?

 

No, I have Harley Davidson embossed on the back pipe.

 

Are you running them on a 1200? Would love to hear their sound.

 

For '98-'03 Sportsters:
Screamin' Eagle II Baloney Cut 80249-99A
Screamin' Eagle II Slash Down 80290-99A

The SE II mufflers for '98-'03 were available in black, too:
Baloney Cut 80322-99A
Slash Down 80325-99A

For '04-'13 Sportsters, the following part numbers went obsolete in '07 when the Street Performance series were released. The SE II mufflers has "Screamin' Eagle II" embossed on a muffler. The Street Perfromance slip-ons have "Screamin' Eagle" on them, without the "II".:
80423-04 is the # for a pair of Slash down, Screamin' Eagle II slip-on mufflers.
80424-04 is the # for a pair of Balony Cut (slash out) slip-ons.
Here's a pic of a box label from a set of slash downs that I've been hoarding. I think they're the best sounding/flowing slip-ons you can find. Not quiet, but not drag-pipe ear splitting, either. Most certainly a little louder than Harley's present offering, the Street Performance slip-ons. The SE II's are not 50-State legal, if anyone cares.
These will not fit an '02 Sportster (Sportsters went to a rubber mount motor in '04).


On my '05 Sportster, a set of the SE II has the SE II in script:

 

I have a set of baloney cut SE 2 mufflers , part # 80424-04.
They fit 2004-2013 XL models (all).
There are no numbers on the mufflers themselves , luckily I got the original box with them.
They are moderately loud , great performers though.

Thank you for the info guys! I knew the real ones had Screamin Eagle II on them, I had them on my '02 Sporty. It seems like the replicas don't have anything on them.

I did some more digging and found out that V-Twin manufacturer makes what seem to be replicas of the SE II's:

http://www.vtwinmfg.com/webapp/wcs/s..._143636_143637

They list that same OEM part number 80424-04. When you click for instructions, it brings up the same PDF as the one franktko posted above. I was under the impression Cycle Shack was making replicas, but apparently it's V-Twin?

Question for you guys with the legit ones, could you tell me the OD of the mufflers? Is it 3"?

 

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.

Interesting. Do you think the perf tube vs. redirect style could make a significant difference? Are you able to post up a video of your bike with the SE II's?
