Mercedes Benz W177, A35 AMG Titanium Valved Catback Exhaust

The lightest and sharpest-sounding exhaust available for the Mercedes-AMG W177 A35 - a full titanium valved catback, built from aerospace-grade titanium with a hand heat-anodised blue finish through the pipework.

The factory A35 exhaust is the quiet one of the W177 range, and it is heavy with it. Going titanium rather than stainless changes both at once: the system is substantially lighter over the rear axle, and the note is sharper and higher-pitched in a way stainless steel simply cannot reproduce.

The valves are controlled from a supplied remote, so the volume is yours to choose rather than the car's. Closed, it is close enough to standard for an early start; open, it is a different car entirely.

Manufactured from titanium throughout with mandrel bends and TIG welds, finished with twin tips and available with your choice of tip finish.

Key Features

Full Titanium Construction

Aerospace-grade titanium through the pipework and tips for exceptional heat tolerance, corrosion resistance and a significant weight saving over both the factory system and a stainless replacement.

Independent Varex Valve System

Rather than reusing the restricted factory valves, this system operates its own dedicated valve assembly with complete travel in both directions. Sealed when closed for a quieter OEM+ driving experience, and fully unobstructed when open for a fully aggressive exhaust tone.

Signature Titanium Exhaust Note

Sharper, higher-pitched and more exotic than stainless, with cleaner overrun, stronger crackles and a distinctly motorsport tone at high RPM.

Heat-Anodised Blue Finish

The colour is produced by heat rather than paint or coating, and it runs through the pipework as one continuous finish. No two systems are identical and the banding will vary slightly from the photographs - that variation is characteristic of anodised titanium rather than a fault.

Precision TIG Welded

Clean, strong welds built to handle exhaust temperature cycling and hard driving.

Direct Bolt-On Fitment

Fits at the factory mounting points and hangers. No cutting and no fabrication.

Performance Benefits

Vehicle Fitment

Mercedes-AMG A35 (W177, 2019-2025)

2.0L Turbocharged M260 Engine

This system is for the A35. The A45 and A45 S run the hand-built M139 and use a different catback - see our W177 A45/A45S listings for those.

Please Note

Professional installation is recommended. Exhaust sound will vary depending on whether the factory or an aftermarket downpipe is fitted.

Check your local road rules before fitting. Exhaust noise requirements vary by state and a vehicle must remain compliant for road use.
