personally I would just get the Magnaflow catback since its all stainless 2.25 mandrel bent piping and a strait through 6x6x14 muffler. I got HatchVX a price on part # 14216 which is a stainless 2.5in oval strait through 14in muffler and it was $71.63 plus shipping. So its all up to you in what you want to do.
