A cat-back exhaust is the single most popular upgrade for the 2016–2024 Chevrolet Camaro SS, and for good reason: it wakes up the LT1 6.2L V8's naturally aspirated bark, trims weight, and lets you dial in exactly how loud your Camaro is at cruise versus wide-open throttle. The best Camaro SS cat-back exhaust depends on how you weigh sound, drone control, tip style, and budget. Below we compare five systems we sell and install at our Tampa, FL shop — from the drone-free CORSA Xtreme+ to the wallet-friendly MBRP — with real fitment, tubing specs, and pricing so you can match the right system to your build.
Our Verdict
The CORSA Xtreme+ 2.75in cat-back is our top pick for the 2016–2024 Camaro SS.
CORSA's patented Reflective Sound Cancellation gives you a loud, aggressive tone at throttle with zero interior drone on the highway — the best of both worlds for a daily-driven SS. Want the loudest possible V8 note instead? Step up to the Borla ATAK. On a budget? The MBRP 3in delivers 80% of the sound for roughly half the price.

A cat-back exhaust replaces everything from the catalytic converters back — mid-pipes, mufflers, and tips — to reduce backpressure and unlock the LT1 V8's true voice. The sixth-generation Camaro SS ships with GM's LT1 6.2L V8 rated at 455 horsepower and 455 lb-ft of torque, pushing a roughly 3,685 lb coupe to 60 mph in about 4.0 seconds. Because the LT1 is naturally aspirated, a cat-back's biggest gains are in sound and weight rather than raw power: expect a typical freeing-up of 5–15 horsepower at the wheels on the SS, plus 10–30 lb of weight savings over the heavy factory system.
Many SS models came with GM's optional NPP dual-mode (bi-modal) exhaust, which uses electronic valves to open under load. The systems below either retain that valve behavior or use passive acoustic technology to control drone, so you get an aggressive tone without a headache-inducing highway resonance. Every kit here is mandrel-bent stainless steel for corrosion resistance — important in humid Florida — and bolts to the factory hangers for a direct fit.

What matters when choosing a Camaro SS cat-back exhaust?
Five factors separate a great Camaro SS exhaust from a regretful purchase:
- Sound level and character: Brands rate their systems on a loudness scale. Borla runs Touring (mild) → S-Type (moderate) → ATAK (loudest). Pick the tone that matches your commute and your neighbors.
- Drone control: The LT1 can boom badly at 1,800–2,200 rpm cruise. CORSA's Reflective Sound Cancellation (RSC) and AWE's 180 Technology are engineered specifically to cancel that frequency.
- Tubing diameter: Most SS cat-backs run 2.75in or 3in mandrel-bent tubing. Larger 3in piping (aFe, MBRP) flows more but tends to be louder.
- Tips and exit style: Quad tips, single split rear, black PVD, chrome, or carbon fiber — this is the visual signature at the rear valance.
- Warranty and material: All five use 304 or T409 stainless; warranties range from limited to Borla's Million-Mile coverage.
The 5 best Camaro SS cat-back exhaust systems compared
The CORSA Xtreme+ is the system we recommend most for a daily-driven SS. Its 2.75in stainless tubing and patented RSC valveless technology deliver a genuinely loud, race-inspired tone at wide-open throttle while staying completely drone-free at highway cruise — something cheaper systems can't match. Twin 4in black PVD tips give it a stealthy look, and CORSA backs it with a lifetime warranty. At around $2,800 it isn't cheap, but it's the most refined sound-per-dollar on this list.
ATAK stands for Acoustically-Tuned Applied Kinetics, and it's the loudest, most aggressive tone in Borla's three-tier lineup. If you want your SS to announce itself, this is the system — a deep, snarling V8 rumble that turns into a full-throated roar at WOT. It uses patented straight-through T-304 stainless mufflers and is covered by Borla's Million-Mile Warranty, the strongest in the industry. Note the single split rear exit with single tips; it will drone more than the CORSA on the highway, so it's best for enthusiasts who prioritize maximum volume.
Borla's straight-through T-304 stainless mufflers produce the loudest tone on this list.
For a max-flow build, the aFe MACHForce XP runs full 3in mandrel-bent 304 stainless tubing — the largest diameter here — making it the natural choice if you plan to add headers, a tune, or forced induction down the road. The larger piping supports the highest flow of any system on this list and produces a deep, aggressive note with blacked-out tips. It's the priciest option at around $3,000, but the 3in path leaves the most headroom for future power adders.
AWE Tuning is known for OEM-plus fit and finish, and the Touring Edition is their balanced option — noticeably more aggressive than stock without the ATAK's volume. AWE's proprietary 180 Technology cancels drone by design, and the quad chrome-silver tips fill the factory rear diffuser cleanly. Backed by an AWE lifetime warranty and priced around $2,200, it's the pick for owners who want a premium look and refined daily manners. (Also offered with diamond-black tips.)
At roughly $1,450 — about half the price of the CORSA or Borla — the MBRP Street version is the value champion. It uses 3in mandrel-bent tubing with quad tips and delivers a genuinely aggressive V8 tone that punches well above its price. The tradeoff is more highway drone than the drone-cancelling CORSA and AWE systems, and T409 stainless tips rather than premium 304 polished. For owners who want a big sound gain on a budget, it's hard to beat.

Cat-back vs axle-back: which is right for your SS?
A cat-back replaces everything from the catalytic converters rearward, including the mid-pipes and mufflers, for the biggest sound and flow improvement. An axle-back swaps only the mufflers and tips behind the rear axle — it's cheaper and installs faster (often under an hour), but the sound change is milder. On the Camaro SS, most of the brands here (Borla, CORSA, aFe, MBRP) offer both, so if the cat-back systems above stretch your budget, an axle-back from the same brand is a smart entry point. For the fullest transformation, though, a cat-back is the way to go.
Installation on a lift is straightforward — these are direct bolt-on systems using factory hanger locations and, where equipped, the OEM NPP valve connectors. Budget 1–2 hours of shop time. Pairing any of these with a set of long-tube headers and a tune is where the LT1 really wakes up, so choose a diameter (2.75in vs 3in) that matches your future plans.

Frequently Asked Questions
How much horsepower does a cat-back exhaust add to a Camaro SS?
A cat-back exhaust typically frees up 5–15 horsepower at the wheels on the naturally aspirated LT1 6.2L V8. Because the SS isn't turbocharged, the main benefits are a louder, more aggressive sound and 10–30 lb of weight savings rather than big power gains. Real horsepower comes when you add long-tube headers and a tune alongside the exhaust.
Which Camaro SS exhaust is the loudest?
The Borla ATAK is the loudest cat-back on this list. ATAK (Acoustically-Tuned Applied Kinetics) is the most aggressive sound level in Borla's three-tier range, above Touring and S-Type. If maximum volume and a snarling V8 roar are your priority, the ATAK is the pick; if you want that aggression only at throttle but a quiet cruise, choose the CORSA Xtreme+.
Will a cat-back exhaust cause drone in my Camaro SS?
It depends on the system. The CORSA Xtreme+ (Reflective Sound Cancellation) and AWE Touring Edition (180 Technology) are specifically engineered to eliminate the 1,800–2,200 rpm highway drone the LT1 is prone to. Louder systems like the Borla ATAK and budget MBRP will produce more cabin resonance at cruise, which is the tradeoff for their aggressive tone.
Do I need a tune after installing a Camaro SS cat-back exhaust?
No. A cat-back exhaust installs behind the catalytic converters and does not require a tune to run safely — it's a bolt-on, emissions-friendly upgrade. A tune is only needed if you also add long-tube headers or high-flow cats that change the pre-cat exhaust. All five systems here retain the factory catalytic converters and NPP valve function where equipped.
What's the difference between a cat-back and an axle-back on a Camaro SS?
A cat-back replaces the mid-pipes, mufflers, and tips from the catalytic converters back, for the biggest sound and flow gain. An axle-back replaces only the mufflers and tips behind the rear axle — it's cheaper and quicker to install but changes the sound less. For the fullest transformation choose a cat-back; for a budget-friendly first step, an axle-back works.
Are these exhausts a direct bolt-on for the 2016-2024 Camaro SS?
Yes. All five systems are direct bolt-on kits that use the factory hanger locations and connect to the OEM NPP dual-mode valve where the car is so equipped. No cutting or welding is required, and install takes about 1–2 hours on a lift. Always confirm your exact year and NPP option against the product fitment before ordering.
Full 3in mandrel-bent tubing leaves the most flow headroom for headers and a tune.
