I like the Pythons on my 05, loud but not to loud. Nice and throaty.

 

If I put Pythons on my 03 Ultra will I have to make other changes?

 

Got 'em on my ,07 SG, they're good quality and have a good deep sound, not too loud. Not a bad buy for the price.

 

Love mine! Loud enough to get noticed when you want. Quiet enough if you don't get on it. They look good and have a nice throaty rumble to them. They were on my 04 FLHT when I got it, bit the mech that owned the bike before me did all the work. True duals. He traded the bike in for an 08 Street Glide. He is now wishing he had kept the 04. My gain!!!
