Cobra downpipe / OPF-delete (Race), BMW M135i B48 (F40) 2020-

Cobra Sport downpipe and OPF delete upgrade for BMW M135i F40 B48 (2.0L) models. This set replaces the original downpipe as well as the OPF front section. Set can be found from our selection with either sport catalyst, or as a decatted RACE / Track version.

Downpipe fits with original standard exhaust, OPF filter is replaced with a small resonator unit that limits unwanted “drone” and resonance. Note, this kit will make your exhaust note significantly more aggressive.

• Made from 304-grade stainless steel
• High quality TIG weldings
• Delivered with accessories
• Diameter 3″ / 76.2mm

Note! Downpipe installation needs an ECU remap to avoid CEL lighting up due to the replaced OEM catalytic converter.
Tuning your engine is highly recommended for gaining the optimal benefits from this upgrade as well.
