C7 Corvette Grand Sport Borla ATAK 11881 with Standard Exhaust (2017-2019)

C7 Corvette Grand Sport Borla ATAK 11881 with Standard Exhaust (2017-2019)

Borla built the ATAK 11881 axle-back for C7 owners who want a sharper, more aggressive exhaust personality on a standard (non-NPP) exhaust setup. On the road, 11881 is the “maximum presence” Borla tone—crisp on throttle, loud when you lean on it, and designed to stay clean at cruise. This is a quad center rear exit system with 4.25" polished T-304 stainless tips.
