Next-Gen AMG, Unleashed

WSTN Performance Catless Downpipes for the 2019–2025 Mercedes A45, CLA45, and GLA45 AMG (M139 2.0L turbo) are engineered to unlock the full potential of the world’s most powerful 4-cylinder engine. By removing the restrictive factory catalytic converter, you’ll get instant turbo spool, raw exhaust note, and increased top-end performance — all built for aggressive driving.

Constructed from stainless steel and wrapped in integrated thermal insulation, this system manages heat effectively without needing external wraps, giving you both performance and protection in one package.

Why Upgrade?

✅ OEM-style heat insulation – Integrated wrap helps manage radiant heat, no external wrap required

✅ Mandrel-bent piping – Removes all restrictions for maximum power

✅ Stainless steel – Built to last under heat and pressure

✅ CNC flanges & TIG welds – Precise fitment and long-term durability

✅ Track-ready sound – Aggressive, raw, and addictive under load

✅ Bolt-on installation – No cutting or welding required

✅ 1-Year Warranty – Peace of mind, even at full send

Bring Your M139 to Life
