Highlighted MAD Upgrades

• Intake Systems: Example—MAD front mount intake for S55 engine (BMW M3/M4) improves airflow, adds induction sound and boosts throttle response. 

• Downpipes & Exhausts: Example—High‐flow downpipes for S58 engine or catless downpipes for S63; smooth bends and large diameter reduce back‐pressure.

How to Maximize Your BMW Build with MAD

• Begin by selecting parts matched to your engine code and chassis (e.g., S55, S58, B58) for proper fitment.

• Pair flow upgrades (intake, charge pipe, downpipe) with appropriate supporting mods (cooling, tuning) for best results.

• Make sure your installation uses quality hardware and seals to avoid boost or air leaks that undermine performance.

• Consider sound level and driving style: Exhaust and intake upgrades change both how the car drives and how it sounds.

• Take advantage of MAD’s warranty and return policy—ensure parts are installed correctly and any issues are addressed early.
