what I would like.

What I would like is the SLP exhaust system. Do you think it is cheaper? I was the only one in my town with the goat, now there is somebody else I met who has a Cyclone Grey one adding mods. One of the mods were a bolt on SLP system #2. It sounds very raw. I like but am still shopping.:)
