I haven't had this system but little over three months and got the y-pipe. It has silencers with it to. But I am trying to get another exhaust system. And if you want strong loud system here it is. If interested Email me @ lovenpain@gmail.com.
I want $500 obo that will include Megan Racing Y-pipe and shipping. Thats a hella deal vs what I paid!

here is a vid after the instal:
