Milltek catless and OPF delete downpipe

Milltek Sport Catless 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 combination of the catalytic converter and the Otto Particulate Filter (OPF) chokes the 2.0L turbo engine, robbing it of power, dulling its throttle response, and silencing the aggressive soundtrack it deserves.

It’s time to unleash its true voice. This Milltek Sport Catless and OPF Delete Downpipe is the single most effective hardware upgrade to uncage your A35.

By removing both of these major restrictions, this precision-engineered downpipe dramatically reduces exhaust back-pressure. This allows the turbocharger to spool faster, work more efficiently, and breathe freely, unlocking a new level of performance and sound. Crafted from high-grade T304L aircraft-grade stainless steel and designed for a perfect, bolt-on fit, this is the essential key to unlocking true Stage 2 performance.

Key Features & Benefits:

• Transforms the Exhaust Note: This is the upgrade you will feel and hear. Expect a much louder, more aggressive, and raw soundtrack with a dramatic increase in pops, bangs, and crackles on the overrun.
• Unlocks Stage 2 Performance: This downpipe is the essential component required for any Stage 2 ECU remap, allowing your engine to produce significantly more horsepower and torque.
• Faster Turbo Spool: By removing all restrictions, the turbo spools faster and more efficiently, resulting in a much sharper and more immediate throttle response.
• Premium Construction: Manufactured from high-quality T304L aircraft-grade stainless steel, ensuring durability and resistance to high temperatures and corrosion.
• Precision Engineering: Designed by Milltek Sport for a 100% bolt-on fit, ensuring a straightforward installation with perfect alignment.

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, manage the new engine parameters, and prevent any engine management lights (CEL) from appearing.
• This product removes both the catalytic converter and the particulate filter. It is therefore intended for motorsport, track, or off-road use only.
