The best C7 Corvette exhaust systems transform the 6.2L V8’s factory tone into a track-bred snarl without touching reliability — and for the 2014-2019 Stingray, Grand Sport, and Z06, the field comes down to Akrapovic titanium and Borla stainless. In our Tampa, FL shop we install these systems on C7s every week, so we built this roundup around the five kits that consistently deliver the best sound, fit, and value. Prices run from $2,799.99 for a Borla axle-back to $6,829.80 for the Akrapovic Slip-On Line.
Our Verdict
Akrapovic Slip-On Line (Titanium) is our overall top pick for the C7 Z06.
For the supercharged LT4 Z06, nothing matches the Akrapovic Slip-On Line: titanium construction sheds serious weight, the carbon-fiber tips finish the look, and the sound is unmistakably exotic. On a budget, the Borla 14-18 Stingray ATAK axle-back delivers the loudest bang-for-buck for the LT1 Stingray at $3,199.99.

The C7 Corvette (2014-2019) ships with a naturally free-flowing exhaust, so upgrades are chosen primarily for sound, weight, and tip style rather than big horsepower. The base Stingray runs a 6.2L LT1 V8 making 455 hp and 460 lb-ft (460 hp with the optional NPP performance exhaust). The 2017-2019 Grand Sport shares that LT1. The Z06 steps up to a supercharged 6.2L LT4 producing a monstrous 650 hp and 650 lb-ft. Because these engines already breathe well, a cat-back or axle-back typically frees only 3-10 rear-wheel horsepower — the transformation is in the acoustics.
Two factory options dictate which kit you order. NPP is GM’s dual-mode Performance Exhaust with electronically actuated valves; AFM (Active Fuel Management) deactivates four cylinders under light load. Borla sells discrete ‘w/ NPP’ and non-NPP versions, plus separate AFM and non-AFM fitments, so always confirm your build sheet before buying. Get it right and the valves and check-engine light behave exactly like stock.
Akrapovic’s titanium muffler and carbon tips are the lightest option for the C7 Z06.

The 5 Best C7 Corvette Exhaust Systems
1. Akrapovic Slip-On Line (Titanium) — Best Overall for the Z06
The Akrapovic Slip-On Line is the gold standard for the C7 Z06. It replaces the rear muffler section with a full titanium assembly and hand-finished carbon-fiber tips. Titanium is roughly 40% lighter than the stainless steel it replaces, so you drop meaningful rear-of-axle weight while unlocking a deeper, race-derived howl from the supercharged LT4. This is jewelry-grade hardware that looks as good as it sounds.
Key Specifications
What We Like
- + Titanium build sheds significant weight over the factory system
- + Exotic, race-derived sound tailored to the supercharged LT4
- + Carbon-fiber tips deliver a premium, unmistakable finish
Things to Consider
- – Premium price — more than double a Borla axle-back
- – Z06-specific fitment (2014-2017); confirm your model year
2. Borla 14-18 Stingray ATAK Axle-Back — Best Value for the Stingray
For LT1 Stingray owners who want maximum volume without maximum spend, the Borla ATAK axle-back is the sweet spot. ATAK (Acoustically Tuned Applied Technology) is Borla’s loudest sound level, delivering an aggressive wide-open-throttle bark from T-304 stainless. With 2.75-inch piping to the muffler and dual 4.25-inch tips, it bolts on in about an hour and is backed by Borla’s Million-Mile Warranty. At $3,199.99 (down from $3,584.99), it is our value pick.
What We Like
- + ATAK is Borla’s loudest, most aggressive sound level
- + Roughly one-hour axle-back install with no mid-pipe work
- + T-304 stainless with Borla’s Million-Mile Warranty
Things to Consider
- – Can drone on long highway pulls at cruise RPM
- – Axle-back only — minimal flow gain versus a full cat-back
Borla’s ATAK dual 4.25-inch tips give the Stingray an aggressive rear-end look.
3. Borla ATAK Cat-Back w/ NPP Dual Mode — Best for Active-Exhaust Cars
If your C7 was optioned with the NPP dual-mode performance exhaust, this Borla ATAK rear-section kit is built to retain your factory valve control. You keep the ability to switch between a quiet Tour mode and full-volume Track mode, now with ATAK’s louder character layered on top. It is the enthusiast choice for owners who want civility on the commute and fury on demand, priced at $3,047.99.
What We Like
- + Retains factory NPP dual-mode valve switching
- + ATAK sound with a quiet valve-closed cruise mode
- + Rear-section design keeps installation straightforward
Things to Consider
- – Requires a factory NPP-equipped car to work as designed
- – Costs more than a fixed non-valved axle-back
4. Borla S-Type w/ NPP Dual Mode — Best Daily-Driver Balance
The S-Type sits one notch below ATAK on Borla’s volume ladder: aggressive under throttle but noticeably more livable at highway speed, with less drone. Paired here with NPP dual-mode support, it is the pick for C7 owners who log real miles and want a refined-but-mean tone. At $2,989.99, it is the value-conscious NPP option.
What We Like
- + Less cabin drone than ATAK on long drives
- + Still delivers an aggressive wide-open-throttle note
- + Retains NPP dual-mode valve functionality
Things to Consider
- – Not as loud as ATAK for those chasing maximum volume
- – NPP-specific fitment; verify your options list
5. Borla Z06 ATAK Axle-Back Black Quad Tips — Best Blacked-Out Look
Built specifically for the C7 Z06 (non-AFM, w/ NPP), this Borla ATAK axle-back pairs the brand’s loudest sound level with black quad tips for a menacing, murdered-out rear end. It is the most affordable way to give the supercharged Z06 a stainless-steel voice, priced at $2,799.99 versus its $3,136.99 MSRP.
What We Like
- + Blacked-out quad tips for a stealth, aggressive look
- + Loudest ATAK sound level on the supercharged LT4
- + Lowest price of our five picks at $2,799.99
Things to Consider
- – Fitment limited to non-AFM, NPP-equipped Z06 cars
- – Axle-back only — no mid-pipe flow gains
Black quad tips give the Z06 a stealthy, track-ready rear.
How to Choose the Right C7 Corvette Exhaust
Match the sound to your driving. If you want the loudest possible note, choose an ATAK system; if you commute or road-trip, the S-Type trims drone while staying aggressive. Akrapovic’s titanium sits in its own category — exotic and race-derived.
Verify NPP and AFM before you buy. An NPP car needs an NPP-compatible kit to keep its dual-mode valves working, and Z06 fitments split between AFM and non-AFM. Ordering the correct version avoids valve faults and check-engine lights.
Decide between weight and value. Titanium (Akrapovic) is roughly 40% lighter than stainless and carries a premium price; Borla’s T-304 stainless delivers the aggressive sound most owners want at less than half the cost, backed by a Million-Mile Warranty. For a full-flow upgrade, a cat-back replaces more piping than an axle-back, but on the free-breathing C7 the power difference is small — buy for sound and looks first.
C7 Corvette Exhaust Installation: What to Expect
Every system in this roundup is a bolt-on that requires no tune and no welding. In our Tampa shop, a C7 axle-back like the Borla Stingray ATAK goes on in about 45 to 60 minutes with basic hand tools — the car up on a lift or jack stands, a few band clamps and bolts, and the factory hangers reused. The Akrapovic Slip-On Line installs the same way, slotting into the OEM mounting points so nothing is permanent.
Because these are rear-section and axle-back kits, the factory ECU needs no reflash and the car will not throw a check-engine light when you order the correct fitment. This is exactly why NPP and AFM matter: a car with the NPP dual-mode option keeps its valve wiring plugged into the new mufflers, and Z06 owners must match the AFM or non-AFM version to their build. Get the fitment right and the exhaust valves open and close on the factory drive-mode logic, just louder.
One cosmetic note owners ask about: after the first few hard heat cycles, titanium tips can develop a blue-gold heat tint near the outlets. That is normal for titanium and part of the Akrapovic look — it is not a defect. Keep your factory exhaust boxed; if you ever sell the car or return to stock for a warranty visit, reinstallation takes under an hour.
Frequently Asked Questions
How much horsepower does an exhaust add to a C7 Corvette?
An aftermarket exhaust adds modest power to a C7 Corvette — typically 3 to 10 rear-wheel horsepower on the 455-hp LT1 Stingray and slightly more on the supercharged 650-hp LT4 Z06. The 6.2L V8 already breathes well from the factory, so the real payoff of a cat-back or axle-back is sound, reduced weight, and larger tips rather than big dyno numbers. For meaningful gains you need long-tube headers, a tune, or forced-induction support.
What is the difference between a cat-back and an axle-back exhaust on the C7?
A cat-back exhaust replaces everything from the catalytic converters rearward, including the mid-pipes, while an axle-back replaces only the mufflers and tips behind the rear axle. On the C7 Corvette, axle-backs like the Borla Stingray ATAK are cheaper, bolt on in about an hour, and mainly change sound and tip style. Cat-backs cost more and flow slightly better because they replace more of the piping. Most C7 owners choose an axle-back for the best cost-to-sound ratio.
Does my C7 Corvette have NPP or AFM, and why does it matter?
NPP is GM’s dual-mode Performance Exhaust option with electronically controlled valves, and AFM is Active Fuel Management, which shuts off four cylinders under light load. It matters because exhaust kits are sold in NPP and non-NPP versions, and separate AFM and non-AFM fitments. A kit labeled ‘w/ NPP’ retains your factory valve wiring; ordering the wrong version can leave valves inoperable or trigger a check-engine light. Check your build sheet or window sticker before buying.
Is the Akrapovic titanium exhaust worth it on a C7 Z06?
The Akrapovic Slip-On Line is worth it for Z06 owners who prioritize weight savings, exotic sound, and jewelry-grade construction. Its titanium muffler and carbon-fiber tips cut significant weight versus the factory stainless unit — titanium is roughly 40 percent lighter than steel — and the sound is deeper and more race-derived than any stainless system. At $6,829.80 it costs more than double a Borla, so it is a premium choice for owners who want the best, not a value buy.
How loud is the Borla ATAK exhaust on a Corvette?
Borla ATAK is the loudest sound level Borla offers, using its patented Acoustically Tuned Applied Technology for an aggressive, high-decibel tone at wide-open throttle while staying tolerable at cruise. On a C7 Corvette it produces a noticeably louder, more aggressive note than the S-Type or Touring options. If you want maximum volume, choose ATAK; if you drive long highway miles and want less drone, the S-Type is the more livable step down.
Will an aftermarket exhaust void my C7 Corvette warranty?
No — under the Magnuson-Moss Warranty Act, installing an aftermarket exhaust cannot automatically void your factory powertrain warranty. A dealer must prove the part directly caused a specific failure to deny that claim. Borla backs its stainless systems with a Million-Mile Warranty, and reputable brands like Akrapovic include their own coverage. Keep your factory parts and installation records to protect yourself.
