FLOW RS3 3.5" Downpipe Audi RS3 / TT RS (DNWA/DAZA)

Flow Audi RS3 / TT RS 3.5″ Downpipe

Unlock the true potential of your Audi RS platform with the Flow Motorsports 3.5″ Downpipe, engineered to significantly improve exhaust flow, turbo response, and overall performance. Designed for the 2.5T platform, this downpipe reduces backpressure and allows the turbo to operate more efficiently under load.

Manufactured from high grade 304 stainless steel and precision formed for OEM-style fitment, this system is designed to work seamlessly with the factory cat-back exhaust or upgraded aftermarket systems. The integrated mid-pipe deletes the OEM resonators, delivering a more aggressive exhaust note while maintaining strong flow characteristics.
