Overview

The CTS Turbo MK2 TTRS/8P RS3 High Flow Downpipe is a performance exhaust component designed for specific Audi models. It features a 4" T304 stainless steel V-band flange and turbo outlet, with a mandrel-bent design for unobstructed exhaust flow.

The downpipe transitions from a 4" diameter to dual 2.5" outlets, connecting seamlessly to secondary catalysts or mid-pipes. It is hand-built to order and test-fitted to ensure exact fitment. Stage 2 software is required to prevent a Check Engine Light.
Show original supplier description
The CTS Turbo MK2 TTRS/8P RS3 High Flow Downpipe is engineered to enhance the performance of the 2.5T engine in select Audi vehicles. Constructed from 304 stainless steel, this downpipe boasts a CNC-machined 4" V-band flange and turbo outlet, coupled with a 4" mandrel-bent design that minimizes restrictions for improved exhaust gas velocity and flow. Designed for optimal clearance, the downpipe splits into a dual 2.5" configuration, utilizing stainless steel flanges to mate with your existing secondary catalysts or high-flow mid-pipes. Each unit is meticulously hand-built to order within CTS Turbo's facility, ensuring precise fitment through rigorous testing in custom jigs. This high-flow downpipe is compatible with any brand of Stage 2 software, which is required to prevent the illumination of the Check Engine Light post-installation. The primary applications for this downpipe are the 2009-2013 Audi TTRS 2.5T and the 2011-2012 Audi RS3 2.5T. Key specifications include a 4" outlet size, a core interlock style flex section for durability, and the use of 304 stainless steel for its construction.
