Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynos are for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number.

APR Exhaust Crackle
Enhance your exhaust note just like Audi’s latest RS models! The APR Exhaust Crackle, lovingly called “pops and bangs” by many, adds a distinct crackle to the exhaust note upon lifting off the throttle, gear changes on a manual, decelerating, or while free revving at a stand standstill. This optional feature is available at no cost, at the time of flashing, for most compatible ECUs at stage 2 and higher stages. For convenience, the feature is only enabled when the vehicle is placed into sport/race mode. Lastly, for safety, this feature has built in hardware protection limits, and will only function when it’s considered safe to do so. We offer this in both a "soft" and "aggressive" mode as illustrated below with our 2019 Golf R featuring a full APR Valved Catback Exhaust System.
