DESCRIPTION
Turn Your AMG Into What It Was Meant To Be
WSTN Performance Catless Downpipes for the Mercedes-Benz A45, CLA45, and GLA45 AMG (M133 2.0T engine) eliminate the factory catalytic converter to deliver maximum exhaust flow, sharper turbo spool, and a raw, aggressive tone that screams AMG.
Crafted from 3.5” stainless steel, this is a bolt-on upgrade for drivers who want real gains and track-level sound. Built to handle serious boost and high temps, with zero compromises.
Why Upgrade?
✅ OEM-style heat insulation – Integrated wrap helps manage radiant heat, no external wrap required
✅ 3.5” 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
