I have Magnaflow everything, from the X-pipe, resonaters and the polished S.S. mufflers. The exhaust system was custom done by the CEG famous Dougs muffler here in SE MI and is true duals. Parts were about $525 and the piping was another $350.00, which included the "mystery mod". Not included in the parts list was (2) flex pipes for the exhaust system, its need when doing true duals. Contact Stazi in the SE MI forum for pricing, he's our hook up for Magnaflows
