Akrapovič Slip-On Exhaust Review: 2023 02 22 – BMW F700GS / F800GS (2013-2018) – Enhanced Performance and Sound
This review details the performance and acoustic improvements offered by the Akrapovič slip-on exhaust system, specifically the model reviewed on February 22, 2023, for the BMW F700GS and F800GS models manufactured between 2013 and 2018. The Akrapovič slip-on, often a sought-after upgrade for adventure motorcycles, aims to enhance both the aesthetic and functional aspects of these popular BMW twins. This analysis focuses on tangible benefits, including power delivery, weight reduction, sound characteristics, and overall rider experience, as observed and documented during this evaluation period. The objective is to provide a detailed, objective assessment for owners considering this exhaust modification for their F700GS or F800GS.
The primary functional benefit observed with the Akrapovič slip-on exhaust is a noticeable improvement in throttle response and low-to-mid-range torque. While the F700GS and F800GS are generally competent performers, their stock exhausts, designed to meet stringent noise and emissions regulations, can sometimes create a restrictive environment for engine breathing. The Akrapovič system, with its optimized internal baffling and larger diameter outlet, allows the parallel-twin engine to exhale more freely. This improved exhaust scavenging directly translates to a more immediate and responsive feel when the throttle is applied. Riders will likely experience a less hesitant acceleration from a standstill and a more robust pull through the gears in the lower to mid-RPM range. This enhanced torque delivery is particularly beneficial for off-road riding or when carrying a passenger and luggage, situations where readily available power is a premium. Dyno charts, while not universally available for every user installation, commonly indicate gains of 2-5 horsepower and a similar increase in torque, primarily within the 3,000 to 6,000 RPM band. These figures, while seemingly modest, contribute significantly to the overall rideability and enjoyment of the motorcycle, making it feel more spirited and less labored.
Weight reduction is another significant advantage of the Akrapovič slip-on. The stock exhaust systems on most motorcycles, including the F700GS and F800GS, are often constructed from heavier stainless steel and incorporate bulky catalytic converters. The Akrapovič slip-on, typically crafted from high-grade stainless steel or titanium for the outer sleeve and internal components, significantly reduces the overall mass. This weight saving, often in the range of 3-5 kilograms (approximately 6.5-11 pounds), contributes to a nimbler feel, particularly when maneuvering the motorcycle at low speeds, during parking, or on trails. A lighter motorcycle is inherently easier to handle, and while this specific reduction might not transform the bike into a featherweight, it is a measurable and impactful improvement that complements the enhanced performance. The relocation of the catalytic converter, often integrated into the stock muffler, to a separate, smaller unit in some Akrapovič systems or its complete removal (where legal and permissible) further contributes to this weight advantage.
The acoustic profile of the Akrapovič slip-on is a defining characteristic and a major draw for many riders. The stock exhaust on the F700GS and F800GS is deliberately muted to comply with noise regulations. The Akrapovič system, conversely, delivers a deeper, more resonant, and sportier sound. At idle, there is a rich, throaty burble that clearly distinguishes it from the stock pipe. Under acceleration, the exhaust note opens up to a satisfying growl without being excessively loud or intrusive. The sound is characterized by a more prominent exhaust note at lower RPMs and a more aggressive, yet refined, tone as the revs climb. It provides audible feedback to the rider, enhancing the sensory experience of riding. Importantly, the Akrapovič system is engineered to avoid excessive drone at cruising speeds, a common complaint with some aftermarket exhausts. The sound is tuned to be an enhancement, not a distraction, and generally remains within acceptable and enjoyable limits for extended riding periods. The specific sound can vary slightly depending on the material chosen for the outer sleeve (stainless steel versus carbon fiber) and the specific model variant, but the overall impression is one of a premium, sporty exhaust note.
The manufacturing quality and materials used in Akrapovič exhausts are consistently lauded, and the slip-on for the F700GS/F800GS is no exception. The welds are precise and clean, the fit and finish are exceptional, and the materials used are of high quality. Whether opting for the classic brushed stainless steel, the race-inspired carbon fiber, or the exotic titanium sleeve, the aesthetic appeal is undeniable. The Akrapovič branding, often a discreetly engraved logo or a well-placed badge, adds a touch of premium quality. The installation process for a slip-on exhaust is typically straightforward, requiring basic tools and a moderate level of mechanical aptitude. Most systems utilize the stock mounting points, and all necessary hardware is usually included. The fitment is generally excellent, ensuring a clean integration with the motorcycle’s existing lines. The longevity of Akrapovič exhausts is also a testament to their quality; they are built to withstand the rigors of regular riding and exposure to the elements, with materials that resist corrosion and heat degradation.
The impact on fuel economy is often a consideration with aftermarket exhausts. While the primary focus of an exhaust upgrade is performance and sound, a more efficient engine due to improved breathing can, in some instances, lead to marginal improvements in fuel efficiency. The enhanced torque delivery at lower RPMs might allow riders to hold higher gears for longer, potentially reducing fuel consumption during steady-state cruising. However, it is crucial to note that aggressive riding with the new exhaust, which is more tempting due to the improved sound and performance, could easily negate any potential fuel economy benefits. Most users do not install aftermarket exhausts with the primary goal of improving fuel economy, but it’s a secondary consideration that may be observed in certain riding conditions.
For the BMW F700GS and F800GS models from 2013-2018, the Akrapovič slip-on offers a compelling package for riders seeking to elevate their motorcycle’s performance, sound, and aesthetics. The system directly addresses some of the inherent limitations of the stock exhaust, providing a more engaging and rewarding riding experience. The gains in throttle response, particularly in the crucial low-to-mid RPM range, make the bike feel more potent and eager. The significant weight reduction contributes to improved handling and maneuverability. The refined and sporty exhaust note enhances the overall sensory engagement of riding. Coupled with the renowned Akrapovič build quality and materials, this slip-on exhaust represents a premium upgrade that is likely to satisfy discerning owners of these BMW adventure motorcycles. It’s a modification that not only improves the functional aspects of the motorcycle but also imbues it with a distinct character that resonates with the spirit of adventure riding. The ease of installation and the quality of the product make it a worthwhile investment for those looking to unlock the full potential of their F700GS or F800GS.
