The MANHART stainless steel OPF-Delete replacement pipes with damper increase the performance of your BMW F40 M135i.
The sound and exhaust flow are increased significantly. This product can only be used in combination with software remapping.
NOTE: For all BMW models with European specification produced from June 2019, an OPF-Deleter is required when you install aftermarket downpipes or OPF-Delete pipes. The deleter cable deals with the limp mode sequences and error codes, which can become visible on the driver’s dashboard of your vehicle. If you don’t have a OPF-Deleter, then make sure to choose “Including OPF-Deleter” from the dropdown list above. All non-European vehicles without OPF filters don’t need a OPF-Deleter and can choose the option “Excluding OPF-Deleter”.
