Borla ATAK Axle-Back Exhaust System with NPP Valves (11925) - 2016-2024 Chevrolet Camaro SS & 2020-2024 Camaro LT1 6.2L V8
Unleash the full, track-dominant acoustic potential of your naturally aspirated 6.2L V8 engine while retaining complete control over your volume with the Borla ATAK Axle-Back Exhaust System with NPP Dual-Mode Valves. Custom-engineered specifically for 2016 to 2024 Chevrolet Camaro SS platforms and 2020 to 2024 Camaro LT1 configurations, this premium system is tailored for enthusiasts who demand the absolute loudest, most aggressive race-inspired sound profile available from the Borla lineup without sacrificing factory driving modes. Standing for "Acoustically Tuned Applied Kinetics," Borla's patented ATAK technology utilizes specialized multi-core internal mufflers that act like a graphic equalizer. It precisely targets, isolates, and amplifies high-frequency racing notes while completely eradicating low-frequency cabin drone. The result is a hyper-aggressive, crisp, and authoritative exhaust note under hard acceleration that remains completely refined and drone-free inside the cockpit during daily highway cruising.
What sets the Borla 11925 apart is its integrated dual-mode functionality paired with a high-velocity performance architecture. This system is designed exclusively for vehicles equipped from the factory with dual split rear exits and functional NPP valves; it arrives with integrated, operational mechanical exhaust valves that seamlessly sync with your Camaro's factory electronics. This lets you swap back and forth between quiet neighborhood cruising and full track volume instantly via your dashboard drive modes. The system features an optimized high-flow engineering layout with a 2.75-inch entry path that splits into dual 2.5-inch exits on each muffler assembly to maximize exhaust gas velocity and throttle response. Fabricated completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this kit prevents deep rust and structural cracking over time. It completely transforms the rear lower valance with a stunning set of quad 4-inch round, rolled angle-cut highly polished T-304 stainless steel tips. Handcrafted via ultra-smooth CNC mandrel bends for an accurate fit and backed by Borla's legendary Million-Mile Warranty, this system brings the ultimate sound of power to your 6.2L Camaro.
For those looking to optimize performance down the road, this axle-back assembly offers an excellent upgrade path. By pairing this kit with Borla's optional X-Pipe with Mid-Pipes—using Part #60607 (for models without AFM valves) or Part #60610 (for models equipped with AFM valves)—you can easily scale this setup into a full high-performance Cat-Back system (applicable to Coupe models only).

Important Application & Compatibility Notes:
- **Exhaust Equipment Requirement:** This system is engineered **strictly for vehicles factory-equipped with the Dual-Mode Performance Exhaust (NPP) package** featuring quad exit tips. It will not drop into standard single-tip bumper valences.
- **Engine Fitment:** Built exclusively for the naturally aspirated 6.2L LT1 V8 engine. Does not fit V6, 2.0L Turbo, or supercharged ZL1 (LT4) models.
- **Cat-Back Expansion Restriction:** While the axle-back system fits both Coupes and Convertibles, expanding this setup with Borla optional Mid-Pipes (60607 / 60610) to form a complete Cat-Back system is **restricted to Coupe models only** due to underbody chassis structural bracing on Convertibles.
