Akrapovic Headers Honda Africa Twin Akrapovic Headers and Linkage Pipes enhance the performance of Akrapovic Slip-On Exhaust systems by promoting greater exhaust flow and back pressure, thus boosting horsepower and torque. They utilize a unique manufacturing process called hydroforming, where pressurized water shapes each tube to optimize exhaust flow without diminishing the steel's strength. These systems not only boost peak power but also improve performance across the entire RPM range, leading to smoother power delivery and a more enjoyable ride. Performance enhancements are precisely measured on specialized in-house flow benches, ensuring consistent and accurate improvements. Features: No fuel remapping required, but for optimal performance RevZilla recommends use of a fuel controller A combination of beautiful machine and hand welds Air-tight quality controlled production means your exhaust will be perfect High-quality, silicon-shielded stainless steel exhaust springs Note: Image for reference only.
