My 97 Burban 454 Had A 2 Into 1 System. After Looking All Over The Net For A New Dual System I Found A Shop That Installed Two New 40 Series Flow Masters Where The Old 2 Into 1 Was And The Two Flow Masters Even Took Up Less Space Than The Old One Did. Then He Ran New Pipes Out The Back Under The Bumper One On Each Side Of The Hitch With Two Foot Chrome Tips For $350.00. You Can Find Systems On The Net, But I Don't Have All The Things To Make A Clean Install So After Buying Off The Net Then Paying For Someone To Install It The Way I Did It Was Alot Cheaper. Look In Like Your Local Free Car And Add Papers At The Stores For Deals, Call All Around It Will Pay Off To Do Some Home Work First Most Off The Time.
Hope This May Help You.
