Sound levels frequently exceed 100 dB, which may violate EU noise regulations (80 dB limit at 50 feet according to EU Regulation 168/2014).
Akrapovic: Engineered for a refined “racing” sound that balances volume with tonal quality. Akrapovic invests in acoustic tuning to create what many riders describe as a “musical” exhaust note. Sound levels typically range 94-102 dB, with most slip-on systems remaining street-legal in Europe when baffles are installed.
REXTORQUE: Custom-tuned sound based on client preferences, with options for both street-legal compliance and track-focused volume. As a custom fabricator, REXTORQUE can design exhaust chambers and baffle configurations to hit specific sound targets, making them ideal for riders in noise-restricted areas.
⚠️ EU Noise Compliance: Under EU Regulation 168/2014, motorcycle exhaust systems must not exceed 80 dB when measured at 50 feet (approximately 15 meters). Many aftermarket exhausts, including high-performance options from all three manufacturers, require baffles installed to meet this requirement. Riders should verify local noise enforcement practices before removing baffles for track use.
Installation Complexity and Fitment Issues
Installation difficulty varies significantly between slip-on systems (typically DIY-friendly) and full exhaust replacements (often requiring professional installation).
Slip-On Installation (1-2 Hours)
All three brands offer excellent fitment for slip-on systems, with minimal modifications required. Arrow and Akrapovic slip-ons typically include:
- Pre-fitted mounting brackets
- Necessary gaskets and springs
- Detailed installation instructions
- Required hardware (bolts, clamps, spacers)
REXTORQUE slip-ons are custom-fitted to specific motorcycle models, ensuring precise alignment without the fitment compromises sometimes found in mass-produced exhausts designed to fit multiple model years.
Full System Installation (3-5 Hours)
Full system replacements require removing stock headers, mid-pipes, and catalytic converters. According to discussions on Triumph Rat forums, Akrapovic full systems generally offer the best fitment due to their extensive R&D investment in CAD-designed mounting points.
Arrow full systems occasionally require minor adjustments to mounting brackets, particularly on older motorcycle models. REXTORQUE custom systems are fabricated specifically for each motorcycle, eliminating fitment issues entirely but increasing lead times (typically 2-4 weeks for custom fabrication).
💡 Installation Tip: Full exhaust systems require ECU remapping to prevent lean fuel conditions that can damage engines. Budget €300-€600 for professional dyno tuning after installation. Pre-programmed fuel maps from manufacturers like Akrapovic and Arrow provide baseline settings but don’t account for individual motorcycle variations, altitude, or fuel quality differences.
Warranty Coverage and Customer Support

Frequently Asked Questions
Is Arrow exhaust as good as Akrapovic?
Arrow exhausts deliver 90-95% of Akrapovic’s performance at 30-40% lower cost. According to dyno testing from DynoBike Australia and forum comparisons on R1-Forum and S1000RR Forum, the horsepower difference between Arrow and Akrapovic full systems ranges from 1-3 HP—well within dyno testing margin of error. Arrow’s TIG welds and titanium construction match Akrapovic’s quality standards, though Akrapovic invests more in R&D for computational fluid dynamics optimization. For most riders, Arrow represents better value unless you prioritize brand prestige or need the absolute maximum performance for competitive racing.
How much HP does an Arrow exhaust add?
Arrow slip-on exhausts typically add 2-4 HP without ECU tuning. Full Arrow exhaust systems with professional dyno tuning can deliver 8-12 HP gains depending on the base motorcycle. According to independent testing, performance gains depend heavily on the stock exhaust restrictions—motorcycles with particularly restrictive OEM systems (like many Euro 5 compliant bikes) see larger improvements. The Arrow Competition series designed for track use provides upper-range gains of 10-12 HP when paired with optimized fuel mapping and removal of catalytic converters.
Why is Akrapovic so expensive?
Akrapovic commands premium pricing due to extensive R&D investment in computational fluid dynamics, proprietary titanium alloys, and MotoGP racing partnerships that drive development costs. The brand has built significant prestige value through 30+ years of racing success, allowing them to charge 40-80% more than competitors for similar materials and performance. Akrapovic exhausts also retain higher resale value (40-50% vs 30-35% for budget brands), partially justifying the initial price premium. However, for riders focused solely on performance-per-dollar, the price premium is difficult to justify based on dyno results alone.
Do I need ECU tuning after installing a full exhaust system?
Yes, ECU tuning is essential after installing any full exhaust system to prevent lean fuel conditions that can damage engines. Removing catalytic converters and stock headers significantly changes exhaust back pressure and airflow, requiring adjusted fuel mapping for optimal performance and engine safety. Pre-programmed fuel maps from manufacturers provide baseline settings but don’t account for individual motorcycle variations, altitude, fuel quality, or additional modifications. Professional dyno tuning costs €300-€600 but typically unlocks an additional 3-5 HP beyond what generic fuel maps provide while ensuring air-fuel ratios remain in safe ranges throughout the RPM band.
Which exhaust is loudest: Arrow, Akrapovic, or REXTORQUE?
Arrow exhausts are typically the loudest with baffles removed, frequently exceeding 105 dB—well above the EU’s 80 dB limit measured at 50 feet. Akrapovic systems emphasize refined sound engineering with volume levels of 94-102 dB, keeping most slip-on configurations street-legal when baffles are installed. REXTORQUE offers customizable sound tuning, allowing riders to specify target volume levels during fabrication. For noise-restricted areas or riders prioritizing street legality, Akrapovic or REXTORQUE with properly designed baffles represent safer choices. Always verify local noise enforcement practices before removing baffles for track use.
How long do titanium exhausts last?
Grade 2 titanium exhausts from all three manufacturers typically last 8-12 years with proper maintenance, significantly outlasting stainless steel alternatives (5-7 years). Titanium’s exceptional corrosion resistance prevents the rust and degradation that plague steel exhausts, particularly in wet climates or winter riding conditions. The primary maintenance requirement is periodic repacking of fiberglass sound dampening material (every 15,000-20,000 km), which costs €80-150 for parts and labor. Titanium discoloration (blue/gold heat coloring) is cosmetic and doesn’t indicate structural weakness—it’s actually prized by many riders for its race-inspired aesthetic.
Can I install a slip-on exhaust myself?
Yes, slip-on exhaust installation is DIY-friendly for mechanically inclined riders with basic tools. The process typically requires 1-2 hours and involves: (1) removing the stock muffler by loosening clamp bolts and springs, (2) cleaning the mounting flange and checking for damage, (3) installing new gaskets provided with the slip-on, (4) sliding the new muffler onto the mid-pipe, and (5) tightening clamps to manufacturer specifications (typically 10-12 Nm torque). Arrow, Akrapovic, and REXTORQUE all provide detailed installation instructions. However, full system installations require exhaust removal, potential fairings removal, and ECU access for tuning—making professional installation advisable unless you have significant mechanical experience.
Are aftermarket exhausts street legal in Europe?
Aftermarket exhausts must meet EU Regulation 168/2014 noise standards (80 dB at 50 feet) and display proper homologation markings to be street legal. Many high-performance exhausts from Arrow, Akrapovic, and REXTORQUE exceed these limits with baffles removed, making them technically illegal for street use in their loudest configuration. However, enforcement varies dramatically by country—some EU nations rarely check exhaust compliance during inspections, while others (Germany, Austria, Switzerland) actively measure noise levels and issue fines for non-compliant systems. Always purchase exhausts with removable baffles and homologation certification, and verify your specific country’s enforcement practices before installation.
What’s the weight difference between titanium and stainless steel exhausts?
Titanium full exhaust systems typically weigh 3-8 kg less than stock systems, while stainless steel aftermarket exhausts save 2-5 kg. For a concrete example, according to Akrapovic’s specifications for the Yamaha MT-09, their titanium slip-on weighs 0.9 kg less than stock (20.4% reduction), while a full titanium system saves approximately 4.2 kg. This weight reduction improves handling by lowering the motorcycle’s center of gravity and reducing rotational mass, which enhances acceleration and braking performance. For more details on motorcycle exhaust weight savings and performance impacts, read our technical analysis. For track-focused riders, titanium’s weight advantage justifies the 40-60% price premium over stainless steel. For street riders, the performance difference is subtle unless you’re riding at 8/10ths or above consistently. To understand the material differences in depth, see our guide comparing titanium vs stainless steel motorcycle exhausts.
How does REXTORQUE compare to premium brands like Akrapovic?
REXTORQUE offers comparable build quality and materials (Grade 2 titanium, ISO 9001 manufacturing standards) at 33-52% lower prices by eliminating distributor markups and focusing on direct-to-consumer sales. Performance gains are similar (5-12 HP with full system and tuning vs Akrapovic’s 10-15 HP), with the difference attributable to Akrapovic’s extensive CFD optimization rather than material quality. The primary trade-offs are longer lead times for custom fabrication (2-4 weeks vs immediate availability from Akrapovic dealers) and lower brand recognition affecting resale value. For custom motorcycle builders and budget-conscious performance enthusiasts, REXTORQUE delivers exceptional value. For riders prioritizing immediate availability, extensive dealer support, or maximum resale value, Akrapovic remains the safer choice despite higher costs.
Do aftermarket exhausts void my motorcycle warranty?
Installing aftermarket exhausts can void warranty coverage for exhaust-related components and potentially engine damage attributed to improper tuning, but manufacturers cannot void your entire motorcycle warranty simply because you installed an aftermarket exhaust. Under EU law (similar to the U.S. Magnuson-Moss Warranty Act), manufacturers must prove that the aftermarket part directly caused the failure before denying warranty claims. However, many dealerships interpret warranty terms conservatively and may refuse claims for any modified motorcycles. To protect yourself: (1) keep stock exhaust for warranty service visits, (2) use manufacturer-provided ECU maps or professional dyno tuning to prevent engine damage, and (3) document all modifications with receipts and professional installation records. Some manufacturers (KTM, Ducati) offer approved aftermarket exhaust lists that preserve full warranty coverage.
What’s the best exhaust for cafe racer builds?
REXTORQUE specializes in custom cafe racer exhausts with hand-fabricated designs that complement retro aesthetics while delivering modern performance. Their custom fabrication approach allows for unique routing solutions, personalized finish options (raw titanium, brushed stainless, ceramic coating), and integration with cafe racer design elements like shorty mufflers, megaphone tips, or vintage-inspired heat shields. Arrow and Akrapovic offer excellent performance but with standardized designs optimized for modern sport bikes rather than custom builds. For cafe racer purists seeking one-of-a-kind exhausts that match their build’s unique character, REXTORQUE’s made-to-order approach provides unmatched flexibility at competitive pricing (€1,200-€2,000 for full custom systems vs €2,500-€4,000 for premium brand alternatives with less customization).
