I just installed some SE slip ons on my 2010 Ultra, I was shocked! They seem quieter than my stock pipes.Will they get louder as packing burns a little, or do I need to get rid of the cat to make them talk a little?

 

If you installed the new SE slipons, they suck. They are EPA restricted. The original SE slipons back in the day (now are Supertrapps) were much better. Ditch them if you're looking for sound. They will get slightly louder, but they still suck. JMO, of course.

 

Yes, the pipes will get louder after you get some miles on them. If you want noise and racket, the SE Touring mufflers are not the ones to go with.

Which SE slip-ons do you have? HD has two SE slip-ons:
SE Street Performance, I think these are 3” diameter, PN 80721-09: one piece
SE Street Performance Touring, 4” diameter, w/EPA stamp, PN 80732-09: requires end caps

I have the PN 80732-09 on my 2009 SG. I was out for a set of pipes that provide more performance and with the least amount of noise. My rider asked to keep the mufflers on the quiet side so we can use the stereo and iPods. At first the mufflers were just a bit louder than stock, as expected. Now there is about 2000 miles on them and they are noticeably louder than stock, but not excessive to us and no issues with the stereo and iPods.

 

The new SE pipes are only slightly louder than stock. They do however meet the EPA restrictions and carry the important EPA stamp. After 1K miles they will develop a little personality, but not much

 

I like the supertrap se with jackpot 2/1/2 headers
power and good sound

 

i was really disappointed by the sound of the se on my 09 . if i knew they were this quiet i should had taken the orginal se of my 06. ended up drilling a few holes in the baffle which worked great.

 

I have the SE 4" touring mufflers (cir 2007) but I recored them with a set of Full Sac 2" baffles!
