Milltek Sport Large Bore Downpipe & Hi-Flow Sports Cat – A35 AMG 2.0 Turbo (2019-On)

Product Description (Body)

Unlock Peak Performance for Your A35 AMG

Engineer your Mercedes A-Class A35 AMG 2.0 Turbo into a performance powerhouse with the Milltek Sport Large Bore Downpipe & Hi-Flow Sports Cat (SSXMZ135). Crafted for the 2019 and later models—both hatch (GPF/OPF) and saloon (Non-GPF/OPF)—this is the ultimate performance upgrade.

Why This Upgrade Works

Maximized Flow, Enhanced Output: Featuring a 3.00″ (76.2 mm) mandrel-bent downpipe, this system significantly boosts gas flow while preserving mid-range torque.
High-Flow Sports Catalyst: Equipped with HJS high-flow catalyst with just 200 cells per square inch, compared to standard 500–600 cps —delivering real performance gains.
Premium Construction: Built entirely in the UK from aerospace-grade T304/T304L stainless steel, known for its non-magnetic, anti-discoloration, and highly durable properties.
Expertly Engineered Sound: Achieve a refined sporty tone that adds character without unwanted drone or resonance.

Track-Ready, Engineered for Stage 2

This system is tailored for motorsport/off-road use only—not EC type-approved. It works best when paired with a Stage 2 ECU remap and may affect road legality, including MOT compliance.

What’s in the Box

MSMZ122: Large-Bore Downpipe with 200 CPSI Sports Cat
MSMZ123: Connecting Pipe
Designed to fit seamlessly with Milltek Sport front resonator bypass or full cat-back systems.
