More then likely the flex is broken and thats where the noise is coming from. I agree with the dealer and have seen several cases where aftermarket front pipes have been installed, and the cat is so bad, that the service engine light illuminates soon after, for catalyst inefficiency. My recommendation? Have your repair facility verify that the flex is indeed bad, cut the flex out and weld a new flex in. Walker makes the flexes, and they are available through Napa, one of many places. For a good job, figure 250 bucks.
