Roxstar Performance – Frequently Asked Questions

Exhaust System Basics

Q5: What is the difference between a slip‑on exhaust and a full system?

A slip‑on replaces only the muffler, offering easier installation and moderate gains. A full system replaces headers and mid‑pipes, delivering maximum performance and weight reduction.

Q6: Do I need ECU tuning after installing an exhaust?

Slip‑ons usually don’t require tuning unless paired with an intake upgrade. Full systems benefit from ECU remapping for optimal air‑fuel ratios and engine protection.

Q7: How much horsepower can an aftermarket exhaust add?

A quality aftermarket exhaust can add 5–15% more horsepower, depending on your motorcycle and setup. Gains are higher with a full system and proper tuning.

Q8: How much weight can I save with an aftermarket exhaust?

Upgrading to titanium, carbon fibre, or stainless steel systems can reduce weight by 3–7 kg, improving handling and acceleration.

Q9: Will an aftermarket exhaust make my bike louder?

Yes. Most aftermarket exhausts produce a deeper, sportier tone. Many include removable dB killers to adjust volume.

Q10: Are aftermarket exhausts legal in South Africa?

Yes, if they comply with National Road Traffic Act noise regulations. Most premium exhausts have features to stay within legal decibel limits.
