09 Design 76mm Fast Flow Downpipe with 200-Cell High-Flow ECE Cat – Ford Focus RS Mk3
Unlock sharper response and stronger mid-range on your Focus RS Mk3 with this 76mm fast flow downpipe from 09 Design. It replaces the restrictive factory part with a smoother, larger-bore path to let the turbo breathe and spool sooner.
The integrated 200-cell high-flow ECE sports cat keeps emissions control in place while allowing far better flow than stock. Expect a deeper, more purposeful exhaust note with minimal drone. Gains are most noticeable when paired with a suitable ECU calibration.
- Direct fit for Ford Focus RS Mk3 2016-2018 2.3 EcoBoost
- Works with the OEM system or most cat-back exhausts
- Lambda sensor ports positioned for correct ECU monitoring
- TIG-welded T304 stainless steel for durability and corrosion resistance
The mandrel-bent 76mm design keeps gas speed high and back pressure low, helping reduce turbo lag. Precision flanges and brackets ensure a secure, leak-free seal.
