BMW G42, 220i/230i Titanium Valved Catback Exhaust

BMW G42, 220i/230i Titanium Valved Catback Exhaust

Take your BMW G42 220i or 230i to the next level with this Titanium Valved Catback Exhaust, engineered to cut weight, improve exhaust flow and deliver a sharper, more aggressive exhaust note with the versatility of switchable exhaust valves.

Designed specifically for the 2.0L turbocharged four-cylinder G42 Coupe, this valved catback replaces the restrictive factory system from the front section back with a lightweight, high-flow titanium design. Electronic valves on the rear silencer let you switch between a refined, comfortable tone and a deep, aggressive soundtrack at the touch of a button.

Built from titanium with precision TIG welding throughout and finished with a heat-anodised colour, it is significantly lighter than a stainless system and offers exceptional strength and corrosion resistance. Supplied with the valve control module, wiring and remotes shown.

Key Features

Lightweight Titanium Construction

Titanium delivers a substantial weight saving over the factory exhaust and stainless steel alternatives, with excellent strength and heat resistance.

Heat-Anodised Titanium Colour

Choose Blue, Purple or Gold. The colour is produced by heat, not paint or coating, so it runs through the pipework and muffler body as a continuous finish and no two systems are identical. Tip finish is selected separately above.

Integrated Valved Exhaust System

Electronically controlled exhaust valves allow you to switch between a quiet cruising mode and an aggressive performance exhaust note.

Valve Controller and Remotes Included

Comes complete with the valve control module, wiring harness and two remotes, so you can open and close the valves on the fly.

Increased Exhaust Flow

Mandrel-bent tubing reduces exhaust restriction for improved engine breathing and throttle response.

Precision TIG Welded

Engineered for maximum strength and long-term reliability under demanding driving conditions.

Choice of Exhaust Tips

Available with chrome, black or carbon fibre style tips to suit the styling of your G42.

Direct Bolt-On Fitment

Designed specifically for the BMW G42 220i and 230i using factory mounting locations for straightforward installation.
