What’s Included
MST Intake System
The MST intake system for the BMW G29 Z4 and Toyota A90 Supra features a large 4" intake pipe, performance dry nanofibre air filter, and laser-cut heat shield, finished in a durable textured black powder coat. Designed to maximise airflow and reduce intake restriction, this system improves throttle response while delivering a more aggressive induction sound compared to the factory setup. Dyno testing on the B58 platform has shown gains of up to 12–14bhp, while retaining OEM mounting points and the standard turbo inlet pipe.
Scorpion B58 OPF Downpipe – 5" Diameter (Choice of Sports Cat or De-Cat)
This package includes your choice of Scorpion 5-inch diameter downpipe, available as either a high-flow sports catalytic version or a de-cat option. Both variants significantly reduce exhaust back pressure compared to the factory OPF-equipped downpipe, allowing the turbocharger to operate more efficiently and support higher power outputs. Precision-manufactured for exact fitment, these downpipes are a key requirement for any serious Stage 2 B58 build. The decat downpipe has slightly more flow and is less expensive but will definitely not pass vehicle emissions tests.
Scorpion Non-Resonated OPF Delete Midpipe
The Scorpion non-resonated OPF delete midpipe for the BMW G29 Z4 M40i and Toyota GR Supra further improves exhaust flow and delivers a sharper, more purposeful exhaust tone. Designed to integrate seamlessly with the Scorpion downpipe and factory rear exhaust sections, this midpipe completes the Stage 2 exhaust hardware setup.
