Please note that the new ART pipes come with a vibration dampening tab that connects to the stock catalytic converter brace. Be sure to connect the tabs and it will damp out vibrational stresses and ride quieter.
The new ART pipes are also now being upgraded from alloy SS439 to SS304, tig welded and deeply polished like the E370 exhaust. They will also come with stock metal crush gaskets at the inlet for a reliable pneumatic seal even with turbos and superchargers.
