Ego-X Catback Exhaust System 3,5" - BMW 335i, 340i F30 F31 (with ECE)

This EGO-X exhaust system for the BMW F30/F31 335i/340i is processed by TIG welding and handmade and consists of absorption silencers, without chambers. The piping diameter is about 3,5" (89mm).

Technical Details:
- Pipe diameter: 3,5" (89mm)
- Pipe material: stainless steel
- Absorption silencer: handmade in our company
- Catback
- TIG welded

Important notes:
Note 1: For the 3.35i a part of the OEM exhaust system has to be taken over and disconnected. (it is about the 50cm long piece of the exhaust system in which the oval flexible pipe is located)
The background is as follows: The oval OEM pipe has a connection diameter of 83mm at the point where our adapter is attached. A production from downpipe in 89mm is not possible due to the position of the OEM downpipe on the 35er models and would mean that this piece has to be manufactured in 76mm. This would represent an 8mm smaller cross-section than OEM and thus a bottleneck. Since we always design our exhaust systems for the maximum possible performance increase, this is the only option.
Note 2: On vehicles with OPF, the OPF is located under the vehicle and integrated into the OEM exhaust system. So, the OEM exhaust system must first be cut behind the OPF, then the EGO-X exhaust system will be mounted with the adapter pipe at the separated point by a clamp.
