High Flow Catted Stainless Steel Downpipe for Mercedes‑Benz A35 A35S AMG W177 2.0T

Upgrade turbo efficiency and exhaust performance on your Mercedes‑Benz A35 / A35S AMG W177 with the STRATEC High‑Flow Catted Stainless Steel Downpipe, engineered to reduce factory exhaust restriction while retaining a high‑flow catalytic converter for balanced street performance.

Constructed from premium T304 stainless steel, this downpipe improves exhaust velocity and reduces backpressure, allowing faster turbo spool, sharper throttle response, and stronger mid‑range power. The integrated high‑flow catalyst delivers noticeable gains with a deeper, more aggressive AMG exhaust tone compared to stock.

Precision fabricated with mandrel‑bent tubing and TIG‑welded construction, this STRATEC downpipe is designed for direct bolt‑on installation using factory mounting points.
