Performance Gains: Unlocking the Potential
One of the primary motivations for upgrading to an aftermarket exhaust system like the Akrapovič slip-on is the expectation of increased engine performance. Dyno testing and real-world riding impressions consistently indicate that the Akrapovič system delivers noticeable improvements in horsepower and torque across the entire RPM range for both the F700GS and F800GS.
While specific figures can vary slightly depending on the exact model year, any associated ECU remapping, and the presence of a dB-killer, the general trend is a power bump. The improved exhaust gas scavenging facilitated by the larger diameter piping and optimized muffler design allows the engine to breathe more freely. This results in a more responsive throttle, particularly in the mid-range, making overtakes and spirited riding more engaging. The peak horsepower figures might see a modest increase, typically in the low to mid-single digits, but the more significant gains are often felt in the torque curve. A fatter torque band means less reliance on downshifting to maintain acceleration, contributing to a smoother and more effortless riding experience, especially on winding roads or when carrying a passenger and luggage.
The weight reduction, as mentioned earlier, also plays a crucial role in perceived performance. A lighter motorcycle accelerates and brakes more effectively, and the Akrapovič slip-on contributes to this beneficial reduction in unsprung mass, subtly enhancing the bike’s overall dynamics.
Sonic Experience: The Akrapovič Sound Signature
The sound of a motorcycle is an integral part of the riding experience, and the Akrapovič exhaust system delivers a distinct and desirable auditory upgrade for the F700GS and F800GS. Removing the stock muffler, which is often designed for quiet operation, unleashes a richer, more aggressive tone.
With the dB-killer installed, the Akrapovič slip-on typically produces a deep, resonant growl that is noticeably more prominent than the OEM system. It’s a sound that announces the presence of the motorcycle without being overly obnoxious or attracting unwanted attention from law enforcement. The note is less tinny and more guttural, conveying a sense of power and performance.
When the dB-killer is removed, the exhaust note transforms into a more visceral and commanding bark. The engine’s character is amplified, with a sharper, more aggressive tone that becomes particularly pronounced under acceleration. The pops and crackles on deceleration, often referred to as "burble" or "rasp," are also more pronounced, adding to the sporty character of the exhaust note. It’s important to note that the sound profile can be influenced by engine RPM, throttle position, and the specific Akrapovič model chosen. However, the overall consensus is that the Akrapovič sound is a significant improvement over the stock exhaust, providing an engaging and satisfying auditory feedback loop that enhances the connection between rider and machine.
Installation: DIY Friendly or Professional Assistance?
For most experienced DIY enthusiasts, the installation of an Akrapovič slip-on exhaust system for the BMW F700GS and F800GS is a relatively straightforward process. The systems are typically designed as direct replacements for the stock muffler, requiring minimal modification to the motorcycle’s existing exhaust mounting points.
The process generally involves loosening and removing the stock muffler, which is usually attached with clamps and bolts. The new Akrapovič slip-on then slides into place, and the mounting hardware is secured. Instructions provided by Akrapovič are generally clear and concise, often accompanied by diagrams or even video tutorials available online. Essential tools typically include a socket set, wrenches, and possibly a torque wrench to ensure fasteners are tightened to the manufacturer’s specifications.
However, for riders who are less mechanically inclined or lack the necessary tools, professional installation at a reputable motorcycle workshop is a viable option. The cost of professional installation will vary depending on the labor rates in your area, but it ensures the exhaust is fitted correctly and securely, minimizing any potential issues. It’s also crucial to ensure that any included springs or seals are correctly installed to prevent exhaust leaks.
Legality and Emissions: Navigating Regulations
The legality of aftermarket exhaust systems is a crucial consideration for riders, particularly concerning noise emissions and catalytic converter presence. Akrapovič is highly conscious of these regulations and offers specific versions of their slip-on exhausts to comply with different market requirements.
For most European and North American markets, Akrapovič provides street-legal versions of their slip-on systems for the F700GS and F800GS. These versions often include a catalytic converter integrated into the muffler or mid-pipe, ensuring compliance with emissions standards. The removable dB-killer is a key feature that allows riders to adjust the noise level to meet local regulations. Riding with the dB-killer removed on public roads where it is mandated can result in fines or other legal repercussions.
It is the rider’s responsibility to be aware of and comply with all local laws and regulations regarding exhaust systems. Before purchasing, it is advisable to check the specific product description and verify its compliance with your region’s emissions and noise standards. In some instances, Akrapovič may offer "for racing use only" versions that do not include a catalytic converter and are designed for closed-course competition.
Value Proposition: Is it Worth the Investment?
The Akrapovič slip-on exhaust system represents a significant investment for the BMW F700GS and F800GS. These are premium aftermarket components, and their price reflects the quality of materials, engineering, and performance gains they offer. The decision of whether it is "worth it" is subjective and depends on individual priorities and budget.
For riders who prioritize a more engaging riding experience, seeking enhanced engine performance, a richer exhaust note, and a reduction in weight, the Akrapovič slip-on can be a very worthwhile upgrade.
