Milltek OPF Delete Pipe for A35 / CLA35 AMG

Milltek OPF Delete Pipe for A35 / CLA35 AMG

Let's be honest, you love your A35, but it's just too quiet. In its most aggressive settings, you know that 2.0L turbo is being held back, muffled by restrictive emissions equipment. The main culprit for this suppressed sound? The Otto Particulate Filter (OPF).

If you're not yet ready for a full Stage 2 downpipe but are desperate to unleash the true voice of your AMG, this Milltek Sport OPF Delete is the perfect solution.

This high-flow, precision-engineered pipe is designed to directly replace the bulky and restrictive factory OPF section of your exhaust. It's a 100% bolt-on part, crafted from high-grade T304L aircraft-grade stainless steel, ensuring perfect fitment and long-lasting durability. By removing this major bottleneck, you uncork the exhaust, allowing for a dramatic increase in sound and performance.

Key Features & Benefits:

• Transforms the Exhaust Sound: This is the upgrade you will hear immediately. It uncorks the exhaust, allowing the 2.0L turbo to have the aggressive, deep note and purposeful pops and bangs it should have had from the factory.
• Improves Exhaust Flow: By removing this significant restriction, you drastically reduce back-pressure. This helps the turbocharger breathe more freely and spool faster.
• Sharper Throttle Response: With better exhaust flow, the engine feels more eager, responsive, and alive to your inputs.
• Premium Construction: Manufactured from high-quality T304L aircraft-grade stainless steel, ensuring durability and resistance to high temperatures and corrosion.
• Direct Bolt-On Fit: Designed to fit seamlessly with your original factory downpipe/catalyst, this pipe replaces the OPF section with no cutting or welding required.

Fitment:

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

CRITICAL INFORMATION:

• An ECU remap (or OPF delete module) is REQUIRED after installation. The OPF system is monitored by pressure sensors, and this pipe will cause an Engine Management Light (CEL) without the correct software calibration.
• This product removes a factory emissions device. It is therefore intended for motorsport, track, or off-road use only.
• This pipe only removes the OPF/GPF. It is designed to be installed with the original, factory-fitted catalytic converter.
