The MANHART stainless steel OPF-Delete pipes with damper increase the performance of your BMW G8x M3 / M4 (Competition / CSL).
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 drivers dashboard of your vehicle. If you dont have a OPF-Deleter, then make sure to choose Including OPF-Deleter from the dropdown list above. All non-European vehicles without OPF filters dont need a OPF-Deleter and can choose the option Excluding OPF-Deleter.
