The part matters — but so does the factory behind it. Here's exactly who manufactures this component.
FactoryPlug is a supply-chain intelligence directory, not a store. We hold no inventory and process no checkouts — this record exists so you can see the real terms before you contact the supplier yourself.
Call it what you want — it's the same part. Younger builders call these M157 downpipes, S63 downpipes and catless downpipes. Old-school guys call them turbo downpipes, exhaust downpipes and downpipe front pipes.
Hunted 2026-09-27 per owner's Google-match method: Google product research first (FF Exhaust $765 304 SS TIG; BlackBoost $399 catless — closest Alibaba-price signal; German Car Accessories; TurboWorks/MTuning; Redstar; MODE; Stone Exhaust), then matched to Alibaba via the exact listing title; same product surfaced by multiple sellers = Alibaba-sourced signal. Retailers' sourcing unverified — listed for visual matching only, never as sourcing claims. Fallback (not needed): Meizhou Xingjihui "W222 5.5T 2015-2020" at $477–499 — starts at 2015, not an exact 2014 match without detail-page verification. Buyer lead: Hak (n0thak) — 2014 S63 AMG, paying Parts Plug member who found nothing for the buyer's car in the vault (churn risk; Conroy handles personally). Search it your way — Younger builders call these M157 downpipes, S63 downpipes and catless downpipes. Old-school guys call them turbo downpipes, exhaust downpipes and downpipe front pipes.
