Where is the best place to buy original style sidepipes with free flowing mufflers like the Classic Chamber cobrapacks. Contemporary uses sidepipes like the original Cobra, same as ERA and Kirkham. I know Cobra Restorers sells them they are the retrictive ones with the 2-1/4" glasspacks. I'm looking for the 3" chambered mufflers. The LOUD non restrictive ones. Without spending an arm and a leg if possible
