I don't know how they sound when seated/riding on the bike but from behind they are horrible.....................and I like loud-ish pipes. Unlike Scrap who must have delicate ears .I bought the Jardine off a member here. He had bought it for his wife. Go figure. He had then stored in original boxes. Figured she didn't have them on long.
Too many flight deck launches behind the JBD's with F14's taking off I guess.
