Frequently Asked Questions About Motorcycle Exhausts in South Africa

At Roxstar Performance, we understand that upgrading your motorcycle’s exhaust system is a significant decision. As South Africa’s premier supplier of performance motorcycle exhausts since 2007, we’ve compiled answers to the most common questions our customers ask about performance exhaust systems.

Does a Sport Exhaust Add Horsepower?

Yes, quality performance exhausts like those supplied by Roxstar Performance typically add horsepower to your motorcycle. Here’s how they improve performance:

• Improved Exhaust Flow: Performance exhausts reduce back pressure and optimize exhaust gas flow, allowing your engine to breathe more efficiently.
• Weight Reduction: Premium brands like Dominator, Speedpro Cobra, Brocks Performance, and Scorpion use lightweight materials that can reduce your exhaust system weight by 40-70% compared to stock systems.
• Measurable Power Gains: Depending on your motorcycle model and the exhaust system chosen, power increases typically range from 2-10 horsepower.
• Enhanced Torque Curve: Many riders experience improved mid-range torque, which translates to better acceleration and riding experience.

While results vary depending on your specific motorcycle and the exhaust system selected, most Roxstar customers report noticeable performance improvements after installation. For maximum performance gains, full exhaust systems generally deliver better results than slip-on options.

How Much Does a Full Exhaust System Cost in South Africa?

The cost of full exhaust systems in South Africa varies based on several factors:

• Entry-Level Systems: Quality full systems start from approximately R7,000-R12,000
• Mid-Range Performance Systems: Premium brands like Dominator and Speedpro Cobra typically range from R12,000-R20,000
• High-End Titanium and Carbon Systems: Premium systems from Brock’s Performance and Scorpion can range from R20,000-R35,000+
• Additional Considerations: Prices may vary based on:
  • Material (stainless steel, titanium, carbon fiber)
  • Motorcycle make and model
  • Import duties and exchange rates
  • Additional components required (fuel controllers, etc.)

At Roxstar Performance, we offer options across all price ranges with financing solutions available for qualifying customers. Contact our team for a specific quote tailored to your motorcycle model and performance goals.

What Exhaust Gives the Best Sound?

The “best” exhaust sound is subjective and depends on personal preference, but different brands have distinctive sound characteristics:

• Dominator Exhausts: Known for a deep, aggressive tone with a distinctive European character
• Speedpro Cobra: Delivers a rich, full-bodied sound with excellent bass notes
• Brock’s Performance: Offers a race-inspired, distinctive sound with a crisp high-end note
• Scorpion Performance: Provides a balanced sound with a distinctive British racing heritage influence

Sound quality is influenced by several factors:

• Exhaust Design: Different internal structures and designs produce unique sound signatures
• Baffle/DB Killer: Many exhausts feature removable sound regulators that can adjust volume and tone
• Material Composition: Titanium typically produces a different sound character than stainless steel
• Full System vs. Slip-On: Complete systems generally produce a more profound sound transformation

At Roxstar Performance, we recommend visiting our showroom where we can demonstrate different exhaust options for your specific motorcycle or connect you with existing customers in your area who can share their experience.

Are Akrapovic Exhausts Legal in South Africa?

Legal status of performance exhausts in South Africa depends on several factors:

• Road Legal Certification: Many Akrapovic and other brand exhausts come with ECE or TÜV approvals, which are generally accepted in South Africa for road use
• Noise Regulations: South African law limits motorcycle noise levels to 105dB. Many performance exhausts with DB killers installed will comply with this limit
• Emissions Standards: Road-legal exhausts should maintain emissions within legal parameters
• Documentation: Always keep your exhaust’s certification documentation with you when riding

While we don’t supply Akrapovic at Roxstar Performance, our premium brands like Dominator, Speedpro Cobra, Brock’s Performance, and Scorpion offer road-legal options with proper certification. We recommend:

1. Choosing exhausts with removable DB killers to manage sound levels
2. Maintaining your original exhaust components for vehicle testing requirements
3. Consulting with our team about the specific legal requirements for your motorcycle model

At Roxstar Performance, we prioritize offering products that balance performance improvements with legal compliance for South African roads.
