The evolution continues with the new GReddy EVOlution GT exhaust line. Improved and refined, this latest generation of Evo exhaust incorporates our new high-flow straight-through internals and limited lifetime warranty. It also retains the benefits of the compact and efficient, offset-tip design of the previous Evo’s muffler. Each EVOlution GT is carefully constructed from precision TIG welded, high-quality 304 stainless-steel. High flow with a deep rich exhaust note is what the GReddy Evo line is known for. *
