    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.
