The EVOlution GT, for the C6 Chevrolet Corvette, combines the best of GReddy’s 40 years of exhaust design expertise, in one unique system. Increased performance, refine exhaust note, and a substantial weight savings come through a creative layout with our distinctive dual EVO mufflers. Large 76mm (3”) mandrel-bent piping is configured with a superior “X-pipe.”  It is then linked to a set of our compact, but highly-efficient, straight-through, mufflers and twin center-exit, 115mm (4.5”) GReddy slash cut tips. In dyno tests, the system gains the C6, 27.2whp / 34.7ft-lb of performance, while producing just an 8-10 decibel increase in sound, (at idle and our test RPM = ¾ redline, 5250). By eliminating the heavy OEM valve system and unnecessary tips, weight is reduced by 34% (-24.2lbs.)

Fitment and installation is top notch and straight forward, with better-then OEM investment cast stainless-steel GReddy flanges. (There is no cutting or sloppy slip-on joints to figure out.) Like all GReddy EVOlution GT systems, they are all made from fully hand-welded, 304 stainless-steel and each exhaust carries a GReddy Limited Lifetime Warranty.
