Scorpion Cat-Back Exhaust System - Mercedes-Benz A-Class (W176) A45 AMG 4MATIC - 76mm
This Scorpion cat-back exhaust replaces the factory system from the catalytic converter back on the Mercedes-AMG A45 (W176). It is built from 76mm (3") mandrel-bent T304 stainless steel pipework. It keeps the factory tailpipe arrangement and fits the original rear diffuser. Choose resonated for a fuller tone with less drone at cruise, or non-resonated for a louder, more aggressive note. Scorpion lists it as fitting either the factory front section or Scorpion's own front pipework. Valved – reuses the factory valve motor(s).
