Next Level Performance
August 11, 2026 • 9 min read
A cat-back exhaust is the single most popular upgrade for the Honda Civic Type R (FK8), and for good reason: the 2.0L K20C1 turbo four already makes 306 hp and 295 lb-ft from the factory, so freeing up the restrictive stock mid-pipe wakes up both sound and top-end response without touching the tune. But the FK8 is unusual — its factory exhaust uses a distinctive triple center-outlet layout, so not every cat-back fits or looks right. At our Tampa, FL shop we get asked "which Civic Type R exhaust is best?" every week, so we lined up five of the most popular options — Borla, aFe, HKS, Invidia and MBRP — and compared them on sound, gains, fitment and price.
Our Verdict
The Borla ATAK Cat-Back is the best all-around FK8 Type R exhaust for enthusiasts who want the loudest, most track-ready sound and a carbon-fiber look.
If you care most about dyno-proven power, the aFe Takeda (+19 hp / +20 lb-ft in aFe testing) is the value performance pick, while the HKS LEGAMAX Premium is the choice for a refined, daily-friendly tone. Every kit here is full T-304/SUS304 stainless and bolts to the factory catalytic converter — no tune required.

A cat-back exhaust replaces everything from the catalytic converter to the tailpipes, so it keeps the FK8 emissions-legal hardware in place while removing the heavy, restrictive factory mufflers and mid-pipe. On the 2017–2021 Honda Civic Type R, the K20C1 2.0L turbo responds well to reduced backpressure: owners consistently report crisper turbo spool, a noticeably deeper exhaust note, and a modest bump in mid-range torque. aFe’s in-house dyno testing on their Takeda system measured up to +19 horsepower and +20 lb-ft of torque at the wheels — real, repeatable gains for a bolt-on that installs in about 60–90 minutes with hand tools.
The FK8’s party trick is its factory triple center-outlet tip layout, where the smaller middle pipe actually reduces highway drone at cruise. Aftermarket cat-backs take two approaches: some (Borla, HKS, MBRP) keep the OEM triple-tip center-exit look, while others (aFe) convert to a wider dual-exit design for a more aggressive stance and tone. Material matters too — every system in this comparison is built from T-304 (or SUS304) stainless steel, which resists corrosion far better than the cheap 409-series steel found in budget knockoffs.
Borla’s ATAK cat-back keeps the FK8’s signature triple center-outlet layout with carbon-fiber tips.
How We Compared These Civic Type R Exhausts
We ranked each cat-back on four things that actually change your ownership experience: tone character (from refined daily-driver to full track volume), fitment and finish (does it retain the OEM triple-tip look or go dual-exit), dyno-backed performance, and price-to-value. The table below scans all five at a glance; detailed breakdowns follow underneath.
| Kit | Tips & Exit | Tone | Best For | Price |
|---|---|---|---|---|
| Borla ATAK Cat-Back (2.75in)Top Pick | Carbon fiber, triple center | ATAK – loudest | Track sound & carbon look | $3,177.99 |
| aFe Takeda 304SS Dual-Exit | Dual 4.5in carbon, dual-exit | Aggressive growl | Biggest gains (+19 hp) | $2,461.00 |
| HKS LEGAMAX Premium | Triple center, OEM-style | Refined & deep | Daily-friendly volume | $2,200.00 |
| Invidia Q300 Titanium Tip | Triple burnt titanium | Moderate–aggressive | OEM look, best discount | $1,835.99 |
| MBRP T304 Triple Center | Triple center outlet | Bold street tone | Best budget T-304 | $1,564.99 |
The Contenders: FK8 Type R Cat-Backs Compared
Borla ATAK Cat-Back — Best Overall & Loudest
Borla’s ATAK (Acoustically-Tuned Applied Kinetics) is the brand’s most aggressive sound level, and on the FK8 it delivers the fullest, most track-ready roar of this group. It uses 2.75-inch, T-304 stainless multi-core tubing, retains the OEM triple center-outlet layout, and finishes with black carbon-fiber tips. Borla backs it with an industry-leading Million-Mile Warranty. One honest caveat: this ATAK version is not CARB-approved, so it cannot ship to California.
Borla ATAK — Key Specifications
What We Like
- + Loudest, most track-ready tone in the test
- + Carbon-fiber tips with OEM triple-outlet fitment
- + Million-Mile Warranty — the best in the class
Things to Consider
- – Highest price of the five kits
- – ATAK volume can drone; not CARB-legal (no CA shipping)
aFe Takeda 304SS Dual-Exit — Best Dyno Gains
If maximum power is the goal, the aFe Takeda is the value performance champ. aFe’s in-house testing recorded up to +19 hp and +20 lb-ft from this system. It steps up from a 3-inch collector into 2.5-inch, mandrel-bent, TIG-welded 304 stainless tubing, with a resonator, dual free-flow mufflers and a center “open-pipe” for an aggressive growl. It ditches the OEM triple-tip look for a wider dual 4.5-inch carbon-fiber exit, and at $2,461 it undercuts the Borla by more than $700.
What We Like
- + Dyno-proven +19 hp / +20 lb-ft in aFe testing
- + Over $700 cheaper than the Borla
- + Aggressive dual 4.5in carbon-fiber exit
Things to Consider
- – Drops the factory triple-tip look for dual-exit
- – Open-pipe design is louder than stock at cruise
The aFe Takeda swaps the OEM triple-tip layout for a dual 4.5in carbon-fiber exit.
HKS LEGAMAX Premium — Best Refined Daily Tone
HKS built its reputation on JDM quality, and the LEGAMAX Premium is the pick for owners who want a deeper, higher-quality note without waking the neighborhood. Made from SUS304 stainless, it keeps the factory triple center-outlet appearance and tunes drone out at cruise, making it the most daily-driver-friendly system here. It fits the full 2017–2021 FK8 run and sits mid-pack on price at $2,200.
Invidia Q300 Triple Titanium Tip — Best OEM Look for the Money
The Invidia Q300 delivers the FK8’s signature triple burnt-titanium tips that mirror the factory layout, but with a fuller, sportier tone. Built from T-304 stainless, it’s currently the value standout of the group: marked down from $2,781.80 to $1,835.99, it’s the cheapest way to get a genuine triple-tip titanium look. It fits 2017–2019 Type R models.
MBRP T304 3in Triple Center Outlet — Best Budget Pick
The MBRP PRO Series is the smart-money choice. At $1,564.99 it’s the most affordable full T-304 stainless cat-back here, uses a full 3-inch pipe, and retains the OEM-style triple center-outlet look. It covers the widest fitment window (2017–2021, including the 2021 Limited Edition) and delivers a bold street tone without the flagship price.
MBRP keeps the factory triple center-outlet look in full 3-inch T-304 stainless.
Sound: What Each FK8 Cat-Back Actually Sounds Like
Tone is the number-one reason FK8 owners upgrade, and these five kits cover the full spectrum from track-loud to daily-refined. In order of volume, the Borla ATAK is the loudest — a hard-edged rasp on start-up with pronounced pops on lift, plus some highway drone around 2,500–3,000 rpm. The aFe Takeda is close behind with an aggressive, mid-heavy growl from its center open-pipe. The Invidia Q300 lands in the middle: a clear step up from stock with a sportier titanium-tip note but manners you can live with. The MBRP gives a bold, muscular street tone while keeping the OEM triple-tip character, and the HKS LEGAMAX Premium is the most refined of all — deeper than factory, but engineered to keep cruising drone in check. If you split time between track days and long commutes, the HKS or Invidia are the easiest to live with; if you want people to hear you coming, the Borla ATAK is the answer.

Installation: Fitting a Cat-Back on the FK8 Type R
Installing a cat-back on the Honda Civic Type R is a straightforward 60–90 minute bolt-on that most owners handle at home with basic hand tools and a set of jack stands. Because a cat-back sits entirely behind the catalytic converter, it does not alter fueling, so no ECU tune is needed and there is no check-engine light. Reuse or replace the factory gaskets and rubber hangers, and use the supplied clamps; every kit here is a direct fit that mounts to the OEM hanger locations. The one detail that matters most on the FK8 is tip alignment — on triple center-outlet systems (Borla, HKS, MBRP), leave the clamps hand-snug until all three tips sit evenly in the rear valance, then torque them down. After the first heat cycle, re-check the clamps once and you are done.
HKS’s SUS304 build retains the factory center-outlet mounting for a true bolt-on fit.
Which Civic Type R Exhaust Should You Buy?
It comes down to how you use the car. For the loudest, most track-ready sound and a carbon-fiber look, buy the Borla ATAK ($3,177.99) — just note it can’t ship to California. For the biggest dyno gains per dollar, the aFe Takeda ($2,461) and its +19 hp / +20 lb-ft is the performance value pick. Daily drivers who want a deeper note without drone should choose the HKS LEGAMAX Premium ($2,200). And if you want the factory triple-tip look on a budget, the discounted Invidia Q300 ($1,835.99) and the MBRP T-304 ($1,564.99) are the two smartest buys in the group. Whichever you choose, you’re getting a full stainless, no-tune bolt-on that transforms how the FK8 sounds and pulls.
Frequently Asked Questions
Does a cat-back exhaust add horsepower to the Civic Type R?
Yes. A cat-back exhaust adds power to the FK8 Civic Type R by reducing exhaust backpressure. aFe’s in-house dyno testing measured up to +19 horsepower and +20 lb-ft of torque from its Takeda system on the 2.0L K20C1 turbo engine. Gains are strongest in the mid-range, and no ECU tune is required because the cat-back retains the factory catalytic converter.
Do you need a tune for a Civic Type R cat-back exhaust?
No, a cat-back exhaust does not require a tune on the Honda Civic Type R. Because a cat-back only replaces piping and mufflers behind the catalytic converter, it does not change fueling or trigger a check-engine light. Downpipes and front pipes are the parts that typically require an ECU tune — a cat-back is a true bolt-on.
Which Civic Type R exhaust is the loudest?
The Borla ATAK Cat-Back is the loudest exhaust in this comparison. ATAK (Acoustically-Tuned Applied Kinetics) is Borla’s most aggressive sound level and produces the fullest, most track-ready tone of the five kits tested. For a quieter, refined note, the HKS LEGAMAX Premium is the most daily-driver-friendly choice.
Will an aftermarket exhaust fit the FK8 Type R's triple center-outlet?
Yes. Every exhaust in this guide is designed for the FK8 Civic Type R. Borla, HKS and MBRP retain the factory triple center-outlet tip layout, while the aFe Takeda converts to a wider dual 4.5-inch exit and the Invidia Q300 uses triple burnt-titanium tips that mirror the OEM look. All are direct bolt-on fitments.
Are these Civic Type R exhausts made from stainless steel?
Yes. All five cat-backs are built from T-304 or SUS304 stainless steel, which resists corrosion and heat far better than the cheaper 409-series steel used in budget systems. Borla backs its system with a Million-Mile Warranty and MBRP offers a limited lifetime warranty.
How much does a Honda Civic Type R cat-back exhaust cost?
A quality FK8 Civic Type R cat-back exhaust runs from about $1,560 for the MBRP T-304 triple-outlet up to roughly $3,180 for the Borla ATAK with carbon-fiber tips. The mid-range HKS LEGAMAX Premium is around $2,200, and the discounted Invidia Q300 titanium-tip is one of the best values at under $1,850.
