Our Verdict
For most 2020–2025 GR Supra owners, the AWE Touring Edition (Resonated) is the best all-around exhaust — a deep, drone-free voice with a Lifetime Warranty and a No-CEL Guarantee.
Want the lightest, most exotic setup regardless of price? The titanium Akrapovic Slip-On is the halo pick. Chasing maximum volume on a budget? The Borla ATAK just under $1,900 is the value champ.
Shop Our Top Pick →A GR Supra exhaust is a cat-back or slip-on system that replaces the restrictive factory muffler on the 3.0L B58 inline-six to improve sound, cut weight, and free up exhaust flow. It is the single most satisfying upgrade you can bolt to the A90/A91 chassis — it wakes up the twin-scroll turbo six and finally lets the engine breathe and bark the way BMW and Toyota muffled from the factory. But with premium titanium slip-ons, single-exit race mufflers, and drone-free daily cat-backs all competing for your money, picking the right one is confusing. At NLP Performance in Tampa, FL, we ship these systems every week, so we lined up five of the best — Akrapovic, HKS, AWE Tuning (x2), and Borla — and broke down sound, weight, power, price, and fitment so you can buy once.
The B58 Supra: Why Your Exhaust Choice Matters
The 2020–2025 Toyota GR Supra 3.0 runs the B58B30 twin-scroll turbocharged 3.0L inline-six. Early 2020 US cars were rated at 335 horsepower and 365 lb-ft; from the 2021 A91 update onward, output climbed to 382 horsepower and 368 lb-ft at the crank, in a car that weighs roughly 3,400 pounds. That is a lot of turbocharged torque trapped behind a heavy, heavily-muffled factory exhaust.
An aftermarket exhaust attacks three things: sound (unlocking the straight-six growl and turbo character), weight (the OE muffler section is cast-heavy), and flow (letting a tuned engine exhale). Be realistic about power, though: on an otherwise stock B58, a cat-back or slip-on adds only low single-digit horsepower. The exhaust is what lets a tuned B58 — which can gain 60–100+ horsepower on an ECU flash — make and keep that power. Buy an exhaust for sound, weight, and looks first; treat power as a bonus that shows up once you add a tune.

GR Supra Exhaust Comparison: At a Glance
Here is how the five systems stack up on the attributes that actually drive the decision — system type, sound character, tip material, and price. Every product name and price links straight to the product page.
| Kit | Type | Sound | Tips | Price |
|---|---|---|---|---|
| AWE Touring Edition (Resonated)Top Pick | Cat-Back | Refined, drone-free | 5″ chrome, T304 SS | $2,495.00 |
| AWE Track Edition (Non-Resonated) | Cat-Back | Loud, track-tuned | 5″ chrome, T304 SS | $1,995.00 |
| Akrapovic Slip-On Line | Slip-On | Deep, exotic | Titanium + carbon | $4,604.63 |
| HKS Super Turbo Muffler | Cat-Back | Raw, motorsport | Single center tip | $3,750.00 |
| Borla ATAK Cat-Back | Cat-Back | Aggressive, drone-free | 4.5″ carbon fiber | $1,883.99 |
Akrapovic Slip-On Line (Titanium): The Premium Statement
The Akrapovic Slip-On Line is the halo piece of any Supra exhaust discussion. Rather than a full cat-back, it is a slip-on: it replaces the rear muffler section and bolts to the factory mid-pipe, so the install is quick and the OE center routing stays put. What you get for the roughly $4,600 asking price is aerospace-grade titanium — a material that is about 40% lighter than stainless steel — hand-finished carbon-fiber tips, and a deep, metallic tone that sounds like nothing else on the road.
What We Like
- + Aerospace titanium — roughly 40% lighter than stainless
- + Hand-finished carbon-fiber tips and a deep, exotic tone
- + Slip-On design bolts to the OE mid-pipe for an easy install
Things to Consider
- – Premium price — the most expensive option here at around $4,600
- – Replaces the muffler section only, not a full cat-back
HKS Super Turbo Muffler: Motorsport Attitude
If your Supra leans JDM, the HKS Super Turbo Muffler (DB42/B58) is the enthusiast statement piece. This cat-back uses a large-diameter single center exit and a straight-through core that delivers a raw, motorsport-derived tone — the sound HKS built its reputation on. At around $3,750 it sits between the Akrapovic and the AWE pair, and it fits the full 2020–2025 GR Supra range including Base, Premium, A91, A91-MT, and 45th Anniversary trims.
The HKS single-exit design is a JDM signature on the GR Supra.
AWE Touring vs Track Edition: The Daily-Driver Debate
AWE Tuning gives GR Supra owners the cleanest either/or in the exhaust world. The Touring Edition is resonated: AWE’s 180 Technology cancels the specific frequencies that cause highway drone, so you get a deeper, richer voice than stock while keeping the cabin comfortable on a commute. The Track Edition is non-resonated: same T304 stainless construction and 5-inch tips, but louder and more aggressive, aimed at drivers who want maximum volume. Both wear your choice of Chrome Silver or Diamond Black tips, both are true bolt-on cat-backs, and both carry AWE’s Lifetime Exhaust Warranty and No-CEL Guarantee.
AWE Track Edition: same build as Touring, non-resonated for extra volume.

Borla ATAK Cat-Back: Best Bang for the Buck
The Borla ATAK is the value play, and it does not feel like a compromise. ATAK is Borla’s loudest, most aggressive sound level, yet the system stays drone-free at cruise thanks to Borla’s patented Polyphonic Harmonizer. The build is legit: T-304 stainless with a 3.5-inch pipe that splits into dual 3-inch, capped with 4.5-inch carbon-fiber tips. It is made in the USA, backed by the Borla Million-Mile Warranty, and at just under $1,900 it is the least expensive system in this comparison.
What We Like
- + Loudest ATAK sound level, yet drone-free on the highway
- + T-304 stainless, 3.5″-to-dual-3″ with 4.5″ carbon tips
- + Made in USA and backed by the Borla Million-Mile Warranty
Things to Consider
- – ATAK volume can be too aggressive for a quiet daily commute
- – Carbon-fiber tips are a love-it-or-hate-it look
How Much Power Will a GR Supra Exhaust Add?
Straight talk: on a stock B58, an exhaust alone adds only a few horsepower — usually low single digits at the wheels. The reason to spend the money is sound, weight, and unlocking flow for what comes next. That next step is a tune. A quality ECU flash on the 3.0L Supra routinely finds 60–100+ horsepower and huge midrange torque, and a free-flowing cat-back or high-flow downpipe is what lets that tuned engine actually move the air. Pair any of these five exhausts with a supporting tune and the difference is night and day; run them stock and you are buying an incredible soundtrack and a few pounds of weight savings. Both are valid — just know which one you are paying for.

Installation, Fitment, and Choosing Your Sound Level
All five of these systems are true bolt-on jobs. In our experience, a GR Supra cat-back or slip-on goes on in about 1 to 2 hours with basic hand tools, penetrating oil, and a jack with stands — no cutting, no welding, and no professional install required. Because they are cat-back and slip-on designs, they retain the factory catalytic converters, so they will not throw a check-engine light on a stock car (AWE even backs that with its No-CEL Guarantee). Fitment covers the 3.0L B58 GR Supra sold in the US from 2020 to 2025 across Base, Premium, Launch, A91, A91-MT, and 45th Anniversary trims. The 2.0L four-cylinder Supra uses different routing, so it is not compatible — always confirm you have the 3.0L before ordering.
The hardest part of the decision is not installation — it is picking your sound level. This is the question we get most from Supra owners in our Tampa shop. If the car is a daily driver and you take road trips, go resonated: the AWE Touring Edition uses 180 Technology to cancel drone, so it is loud when you want it and civil on the interstate. If you want maximum volume and cold-start drama, the non-resonated AWE Track Edition, the HKS Super Turbo Muffler, or the Borla ATAK deliver it — just accept that a non-resonated system can add some cruise drone. Chasing weight and exotic tone over outright volume? The titanium Akrapovic Slip-On is the connoisseur pick.
One more tip: an exhaust is the first piece of a bigger B58 puzzle. If you plan to chase real power later, pair your cat-back with a high-flow downpipe and an ECU tune down the road. The exhaust you buy today will still be the right choice — it simply lets a future tune make and hold the power the 3.0L is capable of. Buy the sound and build you actually want; the rest of the package can follow.
Frequently Asked Questions
Does a GR Supra exhaust add horsepower?
A cat-back or slip-on exhaust alone adds only a few horsepower to a stock B58 GR Supra, usually low single digits at the wheels. The real gains come from an ECU tune, which can unlock 60 to 100 or more horsepower on the 3.0L turbo six. An exhaust is primarily a sound, weight, and flow upgrade that lets a tuned engine breathe.
What is the difference between a slip-on and a cat-back exhaust for the Supra?
A slip-on, like the Akrapovic Slip-On Line, replaces only the rear muffler section and bolts to the factory mid-pipe, so installation is quick and it retains the OE center pipe. A cat-back, such as the AWE, HKS, or Borla systems, replaces everything from the catalytic converter back, giving more control over sound, flow, and weight.
Which GR Supra exhaust is quietest for daily driving?
The AWE Touring Edition (Resonated) is the most refined, drone-free option in this comparison thanks to AWE 180 Technology resonance cancellation. It sounds noticeably deeper than stock while staying comfortable on the highway, making it the best choice for a daily-driven A90 or A91 Supra.
Which GR Supra exhaust is the loudest?
The HKS Super Turbo Muffler and the Borla ATAK are the loudest systems here. The HKS single-exit race muffler delivers a raw motorsport tone, while the Borla ATAK is Borla's most aggressive sound level. Among the AWE pair, the non-resonated Track Edition is louder than the Touring Edition.
Will these exhausts fit the 2.0L four-cylinder Supra?
No. These systems are engineered for the 3.0L (B58) inline-six GR Supra sold in the US from 2020 to 2025. The 2.0L four-cylinder Supra uses different exhaust routing. All five kits fit A90 and A91 chassis Base, Premium, Launch, A91-MT, and 45th Anniversary trims with the 3.0L engine.
How long does it take to install a GR Supra cat-back or slip-on exhaust?
Most GR Supra cat-back and slip-on exhausts install in about 1 to 2 hours with basic hand tools, penetrating oil, and a jack with stands. No cutting or welding is required on these bolt-on systems, so it is a popular driveway job. They retain the factory catalytic converters and will not trigger a check-engine light.
