Has anyone installed the OBX Racing Full Stainless Steel Catback Exhaust on their P5? I'm curious if it's any good as far as sound and performance. It's selling on ebay for $200--Is it a great deal or a waste of money? A new Mazdaspeed Sport Exhaust for the P5 sells for about the same, wondering which one would be the better choice? I'm leaning towards the Mazdaspeed.
