the actual install is a peice of cake. took me about 2 hours total, including enlarging the hole (tin snips or dremel tool can do this really easilly). i personally think it would be a waste of money to have a dealer do it for you. just be sure to soak the band clamp/joint on your old cat back in liquid wrench or some other penetrating product for a few hours before you try to slide it off.I might be interested.
Is the installation done by the dealer(how much)? by me? dont know anything.
