Hey I was looking at getting a yoshi RS-3 full system for my 400ex is there anything you guys can tell me about this exhaust in general. Some of the questions i have about it are..... is it loud?(because i ride by alot of old people at my cabin) DOes it give a good HP gain? Does it have a nice sound? Is it a good quality exhaust? And fo you know of any problems with the exhaust?

Sorry for all the quesiton I just wanna get the right exhaust for my quad so i dont screw up.
