EGO-X exhaust system 3.5″ Mercedes C43 AMG 390 hp (with ECE*)

This EGO-X exhaust system for the Mercedes-Benz C43 AMG 390 hp with OPF is handmade using the TIG welding process. The pipe diameter is 3.5 inches (89 mm) and it finally delivers the sound that the C43 definitely needs to deserve the AMG badge.

This version is suitable exclusively for vehicles with a standard exhaust system without factory flap control.
Not suitable for vehicles with the factory AMG Performance exhaust system (with factory flap control)

We have deliberately retained the OEM front silencer for 2 reasons:

1. It allows easier installation using a push-fit connection and a clamp without any additional welding work

2. Our tests during development showed that the body of the OEM centre silencer contains no insulation, that a replacement pipe made no difference to the sound, and that without this front silencer only the transmission of sound into the cabin changes for the worse.

Technical data:
– Pipe diameter: 3.5″ (89 mm) to 2x 3″ (76 mm)
– Pipe material: stainless steel
– Absorption silencers: handmade in-house
– TIG welded

 ATTENTION: NOT SUITABLE FOR VEHICLES WITH PERFORMANCE (AMG) EXHAUST SYSTEM

With ECE type approval*:
*Applies only to the following selection in the “Operating mode selection” field: Bull-X Tronic control unit (with ECE type approval)

This flap exhaust system has ECE approval, so it can be driven on public roads without being entered in your vehicle documents.
Please note: exhaust systems with ECE approval are not affected by the “flap ban” and may still be used on public roads in full compliance with the law.

While driving you can choose whether to drive in Comfort or Sport mode. If your vehicle has a drive mode selection, control via that selection is also possible.
For vehicles without a drive mode selection, control can be carried out with the supplied button. Its LED lighting shows you whether the flap is currently open (light off) or closed (light on).
The control unit closes the flap automatically in all ranges required by the ECE regulation, regardless of which mode you are driving in.

In general the Bull-X Tronic offers two control modes:
– Sport (Dynamic, Race): within the approved scope of the ECE regulation the flap is always open. When stationary the flap is always closed.
– Comfort mode: the flap is always closed, but within the approved scope of the ECE regulation it opens while driving from 75% throttle opening.

You can find further information in our info video.

Without ECE type approval*:
*Applies to the following 3 options in the “Operating mode selection” field: exhaust flap control via switch / exhaust flap control via remote control / Bull-X Tronic “Race” CAN bus control unit

If the vehicle has a drive mode selection (sport button), control via that selection is also possible.
For vehicles without a drive mode selection, control can be carried out with the supplied button.
The button’s LED lighting indicates whether the flap is currently open (light off) or closed (light on).

If you have also purchased the Bull-X Tronic control unit, it is still possible to open the flap when stationary, but while driving the control unit regulates the exhaust flap in line with ECE guidelines.

In general the Bull-X Tronic offers two control modes:
– Sport (Dynamic, Race)
– Comfort mode (flap opens from 75% throttle position)

The “without ECE type approval” version is not permitted for use on public roads – for racing use only!

ATTENTION! The exhaust system offered is not permitted for road use! With the ECE Bull-X Tronic control and the EC catalytic converter you may legally drive your vehicle on public roads. The use of all other controls and/or catalytic converters is intended for racing purposes only. If, despite our warning, you fit an exhaust system WITHOUT ECE approval, you commit a criminal offence. Possible consequences include: the operating licence becoming invalid, the vehicle being taken off the road, a report for tax evasion, and possible investigations by the environmental authority.
