heyu guys anyone have every use iron rock exhaust for a 4.0...if you did how does it sound and hold up , i tried to ask the guys on mall crawlin but they just commented on spelling mistakes

 

I was thinking of buying there exhaust but an exhaust shop could do it cheaper by the time I shipped it. You can hear the tone of the exhaust on there web site. They have deal you can download to hear it....they have 2 of them one for each style of muffler, turbo or chambered.
