Mercedes-AMG A45s / A45 Valved Cat-Back Exhaust System

This hand-built, made-to-order cat-back system is constructed from high-grade stainless steel, with a titanium upgrade available. It features a dual exit design and integrated valvetronic control, allowing you to switch between a refined daily mode and a more aggressive open-valve sound. Each kit includes full cat-back piping, clamps and fittings, valve actuators (where applicable) and a remote-control valve management system.

Designed specifically for the Mercedes-AMG A45 S W177, the system ensures OEM-style fitment on standard vehicles. Production time is up to four weeks from payment confirmation, with dispatch the next working day once complete.

Due to the bespoke nature of this product, returns are accepted only in cases of confirmed manufacturing defects.
