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.
Fits 2015–2019 Chevrolet Corvette Z06 (C7) 6.2L V8, both automatic and manual.
Also fits 2017–2019 C7 Grand Sport (manual transmission only) when the car has no AFM valves, but does have NPP valves.
Does not support AFM (Active Fuel Management) versions; it is built for non-AFM applications
This is an axle-back only system (rear section swap)—the catalytic converters remain stock
