Frequently Asked Questions About Motorcycle Exhausts

• Q: Are aftermarket motorcycle exhausts illegal in South Africa? 

• A: No, modifying your motorcycle’s exhaust is generally legal in South Africa. However, it must comply with noise regulations outlined in the National Road Traffic Act. Excessively loud exhausts can lead to fines. Many quality aftermarket systems we stock, like those from Dominator and Scorpion, include removable dB killers (baffles) to help you manage sound levels responsibly.

• Q: Why are performance motorcycle exhausts so expensive? 

• A: Premium aftermarket exhausts command higher prices due to several factors compared to stock systems:

• Superior Materials: They utilize lightweight, high-performance materials like titanium, carbon fibre, and high-grade stainless steel, which are more costly.
• Research & Development: Significant engineering and testing (including dyno time) go into optimizing performance (power, torque) and achieving specific sound profiles.
• Quality Manufacturing: Construction often involves precision techniques like TIG welding and hand-finishing for better durability and fit.
• Performance Focus: Their primary goal is enhanced power, sound, and weight reduction, unlike stock exhausts which must prioritize cost-cutting, emissions, and strict noise limits.

• Q: How much do motorcycle exhausts cost in South Africa? 

• A: Prices vary widely depending on the type (slip-on vs. full system), brand, materials, and your specific bike model. As a rough guide for brands we stock:

• Slip-Ons: Quality options often start around R5,000 – R6,500, with premium brands like Vance & Hines or Bassani starting from R9,000+.
• Full Systems: Can start around R7,500+, with premium performance systems often ranging from R15,000 to well over R30,000, especially for titanium or complex designs.

• Q: How hot do motorcycle exhausts get? 

• A: Motorcycle exhausts get extremely hot! Header pipes near the engine can easily exceed 500°C and sometimes reach over 800°C under load. Temperatures decrease towards the muffler tip (around 200-250°C). Always allow the system to cool down completely before touching it.

• Q: What are the best motorcycle exhausts?

• A: The “best” exhaust really depends on your motorcycle, your budget, and what you want to achieve (sound, performance, weight savings, looks). Different brands excel for different applications. At Roxstar Performance, we stock leading brands known for quality and performance, such as Dominator, Scorpion, Vance & Hines, Bassani, SpeedPro Cobra, Brocks Performance, and Rinehart Racing. We can provide expert advice to help you choose the ideal exhaust for your specific needs and bike.

• Q: Why do motorcycle exhausts pop? 

• A: Popping sounds, especially when decelerating (closing the throttle), are typically caused by small amounts of unburnt fuel igniting in the hot exhaust system when it mixes with air. This is often more noticeable with less restrictive aftermarket exhausts. While generally harmless, very loud or frequent popping might suggest an engine tuning issue (running too rich or too lean). If you’re concerned, especially if you notice performance changes, having your bike’s tuning checked is a good idea.
