APR Tuning S6 S7 C7 C7.5 4.0TFSI Catback Exhaust System
Vendor: APR Tuning
The APR Catback Exhaust System personalizes your vehicle’s looks, sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. APR’s straight-through brushed-finished mufflers smooth the exhaust note to a deep growl, without adding restrictions. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise.
Cast 2.75” to dual 2.5” rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system. APR’s cast valve housings enable the vehicle to be fitted with the factory electronic valve actuators, retaining OEM valve operation. Finally, removable 4" polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle.
APR Tuning Part#: CBK0009
NOTE: This system is setup without the center muffler, instead a straight-piped section, creating a more track-aspired exhaust volume. For standard street applications, the complete exhaust system with the center muffler may be the more suitable choice… [part# CBK0011]

Optional & Required Add-Ons:
C7 C7.5 4.0TFSI Center Muffler [optional]
The optional front muffler is responsible for reducing sound volume further. This muffler is recommended for customers who have the APR Tuning Race DPs and want a tamer exhaust note.
C7 C7.5 4.0TFSI X-Pipe [optional]
For vehicles with an APR Race DP and APR Catback Exhaust System, the APR X-Pipe is a must have. This upgrade creates a smooth transition between the two systems and integrates an x-pipe that reduces backpressure. This upgrade smooths out the exhaust note for a more refined sound profile while also increasing peak torque.
