BMW 335i N55 Decat Downpipe E90 E91 E92 E93 2011-2012 — also fits BMW 135i N55 E82 E88 2011-2012
Unlock serious performance and sound from your BMW N55 with our stainless steel catless decat downpipe. Precision fabricated in the UK for the early E chassis N55 engines, this BMW 335i and 135i decat downpipe is engineered to maximise exhaust gas flow, reduce backpressure and deliver faster turbo spool for sharper throttle response and a harder hitting powerband.
Why choose this BMW N55 decat downpipe
- T304 high grade stainless steel, TIG welded for strength, durability and corrosion resistance
- Laser cut flanges 10 to 12 mm for a precise, leak free fit
- Mandrel bent tubing for optimum gas flow, maintaining maximum internal diameter
- Noticeable power gains and a more aggressive exhaust note that sounds fantastic
- Improved turbo efficiency with reduced exhaust backpressure and lower temperatures
- Weight saving compared to the factory catalytic converter
- Designed, fabricated and quality checked in the UK

Installation and support
Professional installation is recommended, as tolerances vary between exhaust systems and the space can be tight. Many customers find this downpipe straightforward to fit. To help prevent a check engine light in most cases, we recommend adding a lambda sensor spacer. You can find compatible spacers in our other items.
