SPDZ1 3” Performance Downpipe — 2016–2018 Ford Focus RS (Catless)

Free up backpressure, wake up turbo spool, and let the 2.3L EcoBoost breathe. The SPDZ1 catless downpipe replaces the restrictive factory unit with a full 3.0” mandrel-bent path for stronger mid-to-top-end pull and a sharper exhaust note.

Why It Wins

• Real Performance: Catless 3.0” design reduces backpressure for quicker spool and stronger top-end. Comparable setups report ~15–20 hp gains when paired with supporting mods.  
• Built to Last: 304 stainless steel tubing, TIG-welded, with CNC-machined flanges and a stainless flex section to handle heat cycles and movement. (Spec style aligns with leading RS offerings.)  
• Sensor-Ready: Two O₂ bungs (primary + auxiliary for wideband or spacer).  
• Complete Kit: Ships with new gaskets and hardware for a confident seal.
• Direct Fitment: Designed for 2016, 2017, 2018 Focus RS (global chassis). Compatible with stock or most aftermarket cat-backs; adapters may be needed in rare cases depending on brand.
