Mercedes Benz C118, CLA35 Stainless Steel Valved Catback Exhaust

Give the CLA35 the voice the badge deserves with this Stainless Steel Valved Catback Exhaust for the Mercedes-AMG C118 CLA35 - a full rear-section replacement with electronically controlled valves, twin tips and a wireless remote kit supplied in the box.

The factory CLA35 exhaust is deliberately restrained. It is the quiet one of the C118 range and it sounds it, which is a shame in a car that otherwise looks the part from every angle. This system replaces everything from the front pipe back with mandrel-bent stainless tubing and a valved rear muffler, so the car stays civil at part throttle and turns genuinely loud the moment you want it to.

The valves are controlled from the 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.

Manufactured from 304 stainless steel with mandrel bends and TIG welds throughout, finished with twin tips and supplied complete with the remote kit and hardware.

Key Features

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.

Wireless Remote Kit Supplied

The complete remote control kit is included in the box - nothing further to source, and no connection to the factory valve motors required.

304 Stainless Steel Construction

Mandrel-bent 304 stainless throughout for consistent bore, corrosion resistance and long service life.

Precision TIG Welded

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

Full Rear Section Replacement

Replaces the restrictive factory centre and rear sections in one piece, rather than only changing the muffler.

Direct Bolt-On Fitment

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

Vehicle Fitment

Mercedes-AMG CLA35 (C118, 2020-2025)

2.0L Turbocharged M260 Engine

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.
