The factory downpipe system consists of smaller, 65mm piping with tight bends and a restrictive high-cell-count catalyst, all of which contribute to restricted performance. We took an unrivalled approach to maximising flow, reducing under bonnet temperatures, and removing restrictions. The 102mm turbine exit transitions slowly into the OE 80mm system, the gradual bends are crucial for maximising performance!
Suitable for OEM & aftermarket cat-back exhaust systems.
Fitting de-cat may result in EML light, a sensor spacer may solve this, but not guaranteed. De-cat for off-road use only.
Each of our Enhance Performance BMW M140 Cat-Back exhausts system are built in-house by hand. We’re proud to construct each system with the highest quality TIG welding and fabrication techniques.
