Titanium Performance Exhaust Upgrade for BMW Z4 G29 B58 with OPF GPF

Unlock the soundtrack your BMW Z4 deserves with this premium Akrapovic titanium rear section and Evolution centre pipe package. Built from ultralight titanium with precision-cast hardware, this valve-controlled system delivers a crisper throttle feel, reduced mass over the factory setup and a beautifully engineered finish. The quad carbon fibre tailpipe finishers complete the rear of the Z4 with an aggressive, OEM-plus look that suits the G29’s lines perfectly.

Designed specifically for OPF GPF-equipped Z4 models with the B58B30C turbocharged straight-six, it integrates with the car’s driving modes for a calm, refined tone in Comfort and a more urgent, motorsport-inspired note in Sport. Pairing the titanium rear silencer with the stainless-steel Evolution Link Pipe Set optimises gas flow for a sharper response and a more involving drive.

Compatibility and approvals

Compatible with BMW Z4 Roadster G29 fitted with engine type B58B30C and a gasoline particulate filter OPF GPF. ECE type approval applies when the titanium rear section is installed on its own on OPF GPF cars. Adding the Evolution Link Pipe Set or optional Akrapovic Sound Kit removes ECE type approval. The original system requires cutting as per Akrapovic installation instructions.
