Frequently Asked Questions for Sportbike, Adventure Touring Motorcycle Exhausts
What is the best exhaust for a BMW R1250GS in South Africa?
Dominator and SpeedPro Cobra are the top choices for the BMW R1250GS available through Roxstar Performance in South Africa. Both offer confirmed fitment for the boxer engine platform, with options across slip-on and full system configurations depending on your performance and sound goals.
Is Dominator better than Akrapovic for sportbikes?
Dominator is Roxstar’s flagship brand and is stocked locally in South Africa, meaning faster delivery and confirmed fitment support. Akrapovic is an internationally recognised brand but is not supplied through Roxstar. For riders wanting expert guidance, local stock availability, and a matched fitment process, Dominator is the recommended choice through Roxstar Performance.
Do I need an ECU remap after fitting an aftermarket exhaust?
For slip-on exhaust upgrades, an ECU remap is generally not required. For full exhaust system replacements, particularly on high-output sportbikes, a remap or fuel management adjustment is recommended to fully realise the performance gains and prevent running lean. Roxstar can advise based on your specific motorcycle and exhaust configuration.
What is the difference between a slip-on and a full exhaust system?
A slip-on replaces only the end canister of your stock exhaust and is the more cost-effective upgrade for improved sound and minor performance gains. A full system replaces everything from the headers to the muffler, delivering maximum horsepower, torque, and weight reduction. Roxstar confirms which option best suits your motorcycle and riding goals.
How long does exhaust delivery take across South Africa?
Roxstar holds local stock in Cape Town, eliminating the 4 to 6 week international import delays common with other suppliers. Delivery is available nationwide across South Africa.
Which exhaust brands does Roxstar stock for sportbikes and adventure bikes?
Roxstar stocks Dominator Exhausts, Scorpion Exhausts, Brock’s Performance, and SpeedPro Cobra for sportbike and adventure motorcycle applications. Each brand is mapped to specific engine configurations and motorcycle segments to ensure the correct performance match.
