Top 7 Aftermarket Exhaust Systems for Superbikes — Sound, Power & Price

An aftermarket exhaust system is the single most impactful upgrade you can make to a superbike. It reduces weight, increases power, transforms the soundtrack, and changes the entire character of the machine. The superbike exhaust market is enormous — dozens of manufacturers, hundreds of products, thousands of claims. This guide cuts through the noise and identifies the seven best exhaust systems available in 2025, across different price points and use cases.

Why Upgrade Your Exhaust?

Modern superbike stock exhausts are designed around three competing priorities: passing EU and US noise regulations, meeting emissions standards, and keeping manufacturing costs reasonable. The result is always a compromise. Aftermarket exhausts are designed around a single priority — performance — and the difference is immediately apparent. Benefits include:

• Weight saving: 4–8 kg savings are common with full titanium systems
• Power increase: 5–15 hp gains from a quality full system with ECU remap
• Sound: A transformative improvement from the stock muffled tone to a genuine racing soundtrack
• Aesthetics: The right exhaust dramatically improves the visual appeal of the bike

Slip-On vs Full System — Which Do You Need?

A slip-on (or end can) replaces only the muffler section, retaining the stock mid-pipes and headers. It is cheaper, easier to install, and provides weight savings and sound improvements. Power gains are minimal (0–3 hp) without an ECU remap. A full system replaces everything from the exhaust headers back. This requires professional installation and an ECU remap to unlock the full power benefit, but delivers the maximum performance improvement and the greatest weight saving.

The Top 7 Exhaust Systems

1. Akrapovič Evolution Line (Full Titanium)

uses Grade 1 titanium throughout, saving up to 7.5 kg over stock. Power gains of 8–12 hp are achievable with an accompanying ECU flash. The sound is extraordinary — a deep, purposeful crack on each upshift and a spine-tingling overrun burble on deceleration. Akrapovič makes fitment-specific systems for virtually every superbike model.

• Weight saving: 4–7.5 kg
• Power gain (with remap): 8–12 hp
• Price: £1,500–£2,500 (full system)
• Rating: 10/10

2. SC Project CR-T Full Carbon

SC Project is an Italian manufacturer producing race-quality exhausts with stunning aesthetics. The CR-T system features a carbon fibre silencer and titanium headers, saving up to 6 kg and producing a sound that is notably more aggressive than the Akrapovič — deeper, louder, with a more mechanical character. Popular with track day riders who want maximum drama.

• Weight saving: 4–6 kg
• Power gain (with remap): 6–10 hp
• Price: £1,200–£2,200
• Rating: 9.5/10

3. Arrow Works Full Exhaust

Arrow is the value champion of the high-end exhaust market. Their Works systems offer Akrapovič-level quality at a noticeably lower price point. Stainless steel construction adds slight weight compared to titanium, but the sound and power gain remain excellent. Arrow exhausts are particularly well-regarded for Honda and Yamaha applications.

• Weight saving: 2–4 kg
• Power gain (with remap): 5–8 hp
• Price: £700–£1,400
• Rating: 9/10

4. Termignoni Full Race System (Ducati)

Termignoni is synonymous with Ducati. The company has supplied exhausts to Ducati’s factory MotoGP and WorldSBK teams for decades, and their road systems carry genuine race heritage. If you own a Ducati, a Termignoni system is the most authentic upgrade you can make. The sound is uniquely Italian — a hollow, mechanical wail that completely transforms the Panigale’s already excellent exhaust note.

• Weight saving: 3–5 kg
• Power gain: 7–12 hp (Ducati-specific)
• Price: £1,100–£2,000
• Rating: 9.5/10 for Ducati owners

5. Yoshimura Alpha T Full System

Yoshimura is one of the oldest names in performance motorcycle exhausts, with a heritage going back to the 1970s in American road racing. Their Alpha T systems offer a distinctly different sound character — slightly richer, with a more traditional race tone compared to the harder European sound of Akrapovič. Particularly popular with Suzuki and Kawasaki owners.

• Price: £800–£1,600
• Rating: 8.5/10

6. Remus HexaCone Slip-On

For riders who want a significant sound improvement and some weight saving without the cost of a full system, the Remus HexaCone is the best slip-on available. The distinctive hexagonal carbon end can saves approximately 2 kg and produces a genuinely impressive sound that is notably louder and more characterful than stock. No ECU remap required for the slip-on fitment.

• Weight saving: 1.5–2.5 kg
• Power gain: 0–2 hp
• Price: £350–£600
• Rating: 8.5/10 (best slip-on value)

7. Austin Racing GP1R Full Exhaust

Austin Racing is a British manufacturer producing hand-made race exhausts that are popular at the sharp end of British Superbike racing. Their GP1R systems are louder than most of the competition — some configurations exceed road-legal noise limits — making them more appropriate for track use. Build quality is exceptional and the weight savings are among the best available. Customer service is second to none.

• Weight saving: 5–8 kg
• Price: £1,000–£1,800
• Rating: 9/10 for track riders

Installation Tips

• Always use new exhaust gaskets when fitting any new system
• Allow the system to go through 2–3 heat cycles before full throttle use to bed in the metalwork
• For full systems, always get an ECU remap from a reputable tuner — do not rely on a generic ECU flash
• Check local noise regulations — many aftermarket exhausts exceed road-legal limits

A quality aftermarket exhaust transforms your superbike. Choose the right system for your budget and use case, and every ride will be more dramatic, more engaging, and more memorable.
