I can supply you with a full 2 1/2" twin mandrel cat back to suit the WL for $740 shipped. Comes with clamps, gaskets and tips. Not too loud and won't drone.
Could you tell me what sections come from where?
Is it true the middle muffler(s) are from the ute (V8 dual cat) and the rear muffler is from a sedan, or is it all ute?
The middle section is manufactured to fit the wagon, ute and Statesman as they all have the same wheel base, one part number fits all. The rear muffler is specifically for a WL Statesman. The brand is Manta.
