One of the definitive, top-tier exhaust upgrades is now available from Dundon Motorsports—a full 321SS construction provides the quality and strength you'd expect for your GT car. This tuned length stepped header set (and flapped side connector) offers a 40whp increase for GT3 owners and 25whp for GT3RS owners with no ECU flash required. By repurposing the OEM center muffler and flaps, Dundon ensures operation devoid of drone, but an incredible aural experience at WOT.
