APR 2.5 TFSI Cast Downpipe Audi TTRS 8N/MK2 & RS3 8P/MK2 (APRDPK0006)

APR. Audi TTRS 8N MK2. Audi RS3 8P MK2. Upgrading the restrictive factory downpipe with the APR Cast Downpipe Exhaust System is a great way to increase performance and add a sophisticated growl to the exhaust note. Ideal performance is achieved through expelling exhaust gasses at maximum velocity through APR’s proprietary, low-turbulence, investment cast downpipe. Designed and assembled in-house, the system utilizes only premium materials and world-class manufacturing techniques to deliver unmatched quality and reliability.

The factory downpipe system consists of smaller, 60mm piping with varying bends and multiple restrictive high-cell-count catalysts, all of which contribute to a less than ideal flow path and hindered performance. APR’s engineers took a multi-step approach to maximizing flow, reducing under hood temperature, and eliminating unnecessary restrictions all in a unique package only APR can deliver. DPK0006
