WSTN Mercedes A45/CLA45/GLA45 AMG Catless Downpipe 2014-2019 (W176/C117/X156)

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.
