Milltek Sport High-Flow Sports Cat Downpipe for A35 / CLA35 AMG

Milltek Sport High-Flow Sports Cat Downpipe for A35 / CLA35 AMG

Let’s be honest, your A35 AMG is a brilliant, sharp-handling hot hatch. But in the era of restrictive emissions equipment, the factory has left it feeling… muffled. The factory catalytic converter and Otto Particulate Filter (OPF) choke the 2.0L turbo engine, robbing it of power, dulling its throttle response, and silencing the aggressive soundtrack it deserves.

For the owner who wants to unlock serious performance without committing to the raw, unadulterated noise of a full decat, the Milltek Sport High-Flow Sports Cat Downpipe is the perfect solution.

This precision-engineered downpipe replaces the highly restrictive factory catalyst and OPF with a single, high-flow 200-cell sports catalyst. This design dramatically reduces back-pressure, allowing the turbocharger to spool faster and work more efficiently. The result is the perfect balance: a significant increase in performance and a deep, aggressive new exhaust note, all while being more refined than a fully catless setup.

Crafted from high-grade T304L aircraft-grade stainless steel, this downpipe is the essential component for achieving reliable Stage 2 power.

Key Features & Benefits:

• Unlocks Stage 2 Performance: This is the essential key to any Stage 2 ECU remap. It removes the main bottleneck, allowing your engine to produce a major increase in horsepower and torque.
• Enhanced, Refined Sound: This downpipe completely transforms your exhaust note. It delivers a much deeper, sportier, and more purposeful sound with enhanced pops and crackles, but without the harsh, extreme volume of a decat.
• Faster Turbo Spool: By significantly reducing back-pressure, the turbo spools faster. This sharpens throttle response and makes the car feel much more urgent and alive.
• Premium Construction: Manufactured from high-quality T304L aircraft-grade stainless steel, ensuring durability and resistance to high temperatures and corrosion.
• Direct Bolt-On Design: Engineered by Milltek Sport for a perfect, 100% bolt-on fit, ensuring a straightforward installation.

Fitment:

• Mercedes-AMG A35 (W177)
• Mercedes-AMG CLA35 (C118)

CRITICAL INFORMATION:

• A Stage 2 ECU remap is ESSENTIAL after installation. This is required to optimise performance, adjust for the new airflow, and prevent any engine management lights (CEL) from appearing.
• This product replaces the factory emissions devices with a high-flow sports catalyst. It is therefore intended for motorsport, track, or off-road use only.
