I have the RK slash cuts, I like them alot, They are not loud just give the bike a mellow tone. If you want loud, they probably arent the way to go. Some guys drill them out, I never thought that sound was too pleasing. I had a set of Samson fishtails, they were beautiful pipes, nice shape and great chrome. They sounded sweet idling but way too loud for me while cruising. I aint into loud pipes.
