I want to run staight 4'' from the cat back . My ? is will doing that void my warranty. If i can what will it sound like . I had one person tell me it would not be very loud because of the CAT. I hate that trotline weight. Also when are they coming out with the edge or bulldog boxes or something. [ also how do you post your truck layout at the bottom. having a problem]
