For more information, visit www.P65warnings.ca.gov.The APR Catback Exhaust X-Pipe (CBK0027) is a high-performance modular component designed specifically for Audi C7/C7.5 S6, S7, RS6, and RS7 owners running 3" midpipes (such as those included with certain downpipe systems). This upgrade serves as the critical junction between larger 3" midpipes and the 2.75" APR Catback Exhaust, featuring an integrated X-pipe that optimizes exhaust gas scavenging and reduces backpressure for the 4.0T V8 engine.
By allowing exhaust pulses from both cylinder banks to merge and equalize, the integrated X-pipe design smooths out the raw V8 exhaust note into a more refined, exotic-sounding profile while simultaneously increasing peak torque. Constructed from premium T304 stainless steel and featuring argon-back-purged TIG welding, this component is built to withstand extreme heat and resist corrosion for the life of the vehicle.
Features:
- Integrated X-Pipe Design: Promotes exhaust gas scavenging between cylinder banks to improve volumetric efficiency and increase torque.
- Acoustic Refinement: Smooths out the "choppy" V8 note for a more sophisticated and aggressive tone without adding rasp.
- 3" to 2.75" Transition: Mandrel-bent brushed tubing provides a seamless flow path from 3" aftermarket midpipes into the APR catback system.
- Backpressure Reduction: Larger-than-stock diameter piping and optimized junctions allow the turbochargers to spool faster.
- Premium Construction: Full T304 stainless steel with back-purged welds ensures maximum structural integrity and high-end aesthetics.
- Complete Hardware: Includes new APR slip clamps to ensure a secure and leak-free installation.
Product Contains:
- (1) T304 Stainless Steel Integrated X-Pipe Assembly
- (1) Set of High-Strength APR Slip Clamps
Configuration Note: This part is specifically designed to bridge the gap between 3" midpipes and the APR Catback Exhaust System. It is not intended for use with the factory OEM midpipes or the factory exhaust system.
Warranty: This product is supported by APR’s Limited Lifetime Warranty.
