I am thinking about replacing the exhaust system myself. The garage I brought it to said I need the exhaust system replaced from the cat back. The parts they quoted my on are gasket, mid pipe, muffler, intermidate pipe, and bolts. When I look at the only diagram I can find on line at Auto Zone's web site they also mention a resinator. Is the resinator the same as a mid pipe? What is the gasket for? The guy at the garage never said anything about a resinator. Any help you could give me would be great. Thanks
