That's what I thought originally. But there is no writing on them. Samson I thought had writing on them.. also the ripsaws I've seen the ends (tips) are at an angle. These are flat. They sound bad *** though. Just a little loud for my liking. I want to go with some long shots.
Samson Street Sweepers are angled out a bit. Ripsaw's look just like these. A friend of mine has them on his 2001 Soft Tail. No writing on them but I helped him install them in 2002 and they were from Samson. In fact, I was with him when he ordered them on his computer. Could be a copy, though.
yeah i think they are basically the same ripsaw and ground pounder just the tips have different angles. the ripsaw have a 45 degree cut or so. the ground pounders are at a 90 degree cut.
