APR Presents the 4.0T Cast Race DP Exhaust System!

This upgrade increases power and torque substantially. Expect 635-721 HP with 668-849 FT-LBS of torque, depending on octane (91, 93, 100, or 104). This translates to +96-220 HP, with +123-311 FT-LBS of torque over stock out of the V8! Best of all, APR’s proven track record over the past 6 years with this motor on the Audi S6, RS6, S7, A8, S8, and RS7 gives us the confidence to also offer this ECU Upgrade with a limited powertrain warranty for the term limit of your vehicle’s factory warranty. We call it APR Plus, and it offers 635 HP with 668 FT-LBS and only requires using 91 octane or higher.

We’re excited to announce our ECU Upgrades are now available for the new 2020 R8 V10 Performance models! With an APR ECU Upgrade power climbs substantially. Expect between 634 and 653 HP, depending on octane, with 420-427 FT-LBS of torque! This is available with our EMCS program switching allowing you to switch between 91, 93, or E60-E85 fuel grades for increased power as the octane goes up! The install only takes minutes at an APR dealer and installs directly over the vehicle’s OBD-II port with no ECU removal required. Furthermore, no hardware is required to meet these power upgrades, though the ECU upgrade is designed to pair nicely with a performance catback exhaust system for even more power. Lastly, for those looking for a little more peace of mind, our warranty program, APR Plus, is available offering 634 HP and a factory term limit matching limited powertrain warranty.
