Ordered SE II last week and was told there were only 5 left .Picked them up to-day but they were the HD inscripted ones #80412-04 although the had SE label on it ,now the HD dealer said that is all they can get.As I understand these are not very noisy,what are the SE performance shorties for 07 HD #80503 all about and do they fit a 04

 

The original SEII exhaust like I have #80424-04 which have the Screamin Eagle II scriptand are not street (EPA) legalare no longer offered and I believe were discontinued in 05-06. All of the newer ones and HD scripted are the 50 state legal ones that meet sound and emmision standards. The newer ones are just slightly louder than stock and are not as free flowing from what I understand. Cycle shack I'm told made the original ones for HD and should be the same as the old SEII. I think that latter ones you listed are those with the catlyst in them.

 

If you want a lot more volume you probably don't want the street legal SE Performance pipes. I have them and they work great for me but they are not as loud as the SEII's.

Here's a video I did if you want to hear em:

Yes, you are right, those are the street legal one, not as loud as the one they had before.

 

the SE street performance #80503-07 only work on 06 & 07 I was told.The SE II were made by cycle shack for HD but had larger baffles then their own brand.Was told some dealers in the USA still have some left over so will be searching the web
