Product Description

The Borla 11921 is an ATAK axle-back exhaust system for the 2016-2024 Chevrolet Camaro SS and 2020-2024 Camaro LT1, designed for vehicles equipped with the NPP Dual Mode Exhaust or dual split rear exit bumper. ATAK (Acoustically Tuned Applied Kinetics) is Borla's most aggressive street-legal sound level - delivering the highest decibel output in the Borla Camaro lineup with no interior drone at cruise speed, achieved through vehicle-specific acoustic tuning of the internal muffler cores. The quad 4" polished round tips give the Camaro a clean, performance-focused rear appearance.

Constructed from 100% T-304 austenitic stainless steel and manufactured in the USA, this system uses 2.75" mandrel-bent CNC inlet piping into a straight-through multi-core muffler design with dual 2.5" outlets and a dual split rear exit. NPP valves are not included - add Borla Adapter Kit 60605 to retain dual mode exhaust functionality. For a complete Cat-Back system (coupe only), pair with X-Pipe 60607 or 60610. Backed by Borla's Million-Mile Warranty.
