Borla S-Type Axle-Back Exhaust System Without NPP Valves (11920CB) - 2016-2024 Chevrolet Camaro SS & 2020-2024 Camaro LT1 6.2L V8
Strike the perfect balance between track-inspired energy and street-legal refinement with the Borla S-Type Axle-Back Exhaust System. Custom-engineered specifically for 2016 to 2024 Chevrolet Camaro SS platforms and 2020 to 2024 Camaro LT1 configurations, this premium system delivers Borla's legendary "S-Type" (Stinger) sound profile. It is meticulously tuned for naturally aspirated 6.2L V8 owners who want a deep, robust, and muscular exhaust note under hard acceleration without the extreme volume of a full race setup. Borla's straight-through, multi-core internal muffler configurations target and isolate harsh frequencies to prevent annoying interior cabin drone, giving you a smooth and sophisticated acoustic experience during daily highway cruising while maintaining an authoritative external presence.
What sets the Borla 11920CB apart is its stealth styling paired with a versatile non-valved layout. This axle-back system does **not** include integrated NPP dual-mode valves, making it the perfect choice for owners who want consistent, deep sound all the time or are converting their single-tip bumper setup over to a quad-tip lower valance. However, if your car is equipped with the factory dual-mode exhaust and you decide you want valved control later, Borla's optional Adapter Kit (Part #60605) can be used to add functional NPP valves to this assembly. The system features an optimized high-flow engineering layout with a 2.75-inch entry path that splits into dual exit paths 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 lined tips coated in a durable, high-temperature ceramic black finish. 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:
- **Bumper Cover / Valance Requirement:** This system features quad output tips and fits models equipped with the factory Dual-Mode Exhaust (NPP) or a dual split rear exit bumper. For single-exit models, it can be installed if converting to a quad-tip dual split rear bumper cover.
- **NPP Valve Status:** This unit is supplied **WITHOUT internal NPP valves**. To implement functional dual-mode valving, Borla Adapter Kit 60605 must be purchased separately.
- **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.
