3 inch flex joint for custom downpipe applications. Required when the stock exhaust donut set up is eliminated. This will prevent your exhaust system from being subjected to the constant vibrations of the engine. Also reduces exhaust pipe movement virtually eliminating chances of the undercarriage contact with the catalytic convertor, muffler or pipes.
Note: This is the 12 inch long version which provides an additional reduction of engine movement to the exhaust system.
