# APR 13-18 Audi S6/S7/RS6/RS7 (C7) w/APR Catback Exhaust X-Pipe Kit

For vehicles with an 3" midpipes and an 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. Like the rest of the system, the x-pipe is constructed from T304 stainless steel, beautifully TIG welded, and includes all new APR slip clamps.

-   In-house design with world-class manufacturing and quality control
-   Dual 3" to 2.75" mandrel-bent brushed tubing
-   For use with 3" midpipes to and APR Catback

-   T304 stainless-steel construction
-   Lower exhaust back pressure
