Id like to stay with slip ons rather than a full system. Sure like the look of the left and right dual pipes. Any feed back on this brand for quality? sound?

haven't used them, or heard them, but i do like the look of the underseat pipes.

They look very close to my Zard system but I am unfamiliar with the manufacture.  I really like my Zard pipes but I am not sure if they make a slip on system.
