Why not magnaflows? I think the catback system described is a good idea, or you can just do a single in/dual out magnaflow muffler and just run the pipes out to the rear of the car like I have in my dakota. The sound of the flows is loud (and you get no HP from it), Borla's and Bassani's are even louder. Magnaflows are a good deep V8 sounding mufflers that make even slow Dakotas sound mean.
