Borla ATAK Axle-Back Exhaust System – Precision-Engineered for 2014 to 2019 C7 Corvette

Description

The Borla ATAK Axle-Back Exhaust for C7 Grand Sport / Z06 unleashes your Corvette’s voice with a bold, aggressive tone while preserving performance. Designed to attach to your factory catalytic converters, it transforms the rear sound without overhauling the entire system. Built from T-304 stainless steel using Borla’s straight-through and multi-core technology, it optimizes flow and durability. And because it retains the NPP (dual-mode) valve functionality, you keep factory exhaust control.
