The APR CD100004 Audi A6 Cat and Downpipe Exhaust replaces the exhaust from the turbochargers to behind the lower factory catalytic converters. The APR system removes the factory pre-cats right off of the turbocharger and includes six separate components. Included with the CD100004 are the two pipes off of each turbocharger, a set of pipes with catalytic converters, and a set of test pipes without cats. With TIG welding, fully stainless construction, and CNC'ed hangers, you will not find a higher quality downpipe system on the market.

Note:
Does not fit Tiptronic equipped vehicles.
