A GPF/OPF bypass pipe for the F70 M135i. The particulate filter acts much like a secondary catalyst, and removing it reduces restriction for improved performance and sound.
Please note: This product is intended for off-road/motorsport use only and is not road legal. An ECU remap is required. This version is designed to fit with the original (OE) exhaust after the filter.
