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.

APR Ignition Coils are designed to be a direct plug-and-play upgrade to factory coils, and provide greater energy output, ensuring a stronger and more consistent spark. The commonplace replacement of factory ignition coils with those taken from the higher output Audi R8 is popularly believed to provide greater energy output. However, testing proves that they are no more powerful than the factory coils that are found on other engines. APR Ignition Coils increase energy output by up to 10% over stock. They are a direct upgrade or replacement, and come with a unique red, blue, or grey housing!
