BMW 3 Series / Z4 – Custom Rear Exhaust Section & Carbon Fibre Blue-Effect Tips at MIJ Exhaust!

This BMW 3 Series Z4 rolled into MIJ Exhaust ready for a subtle but effective upgrade, and we delivered with a custom rear exhaust section, finished with one tailpipe at each end and upgraded carbon fibre tips with a blue-effect chrome finish.

The bespoke rear section enhances the exhaust note, giving the car a deeper, sportier tone without overpowering refinement. Visually, the dual-exit layout transforms the rear end, adding balance and a more aggressive stance that suits BMW’s performance DNA perfectly.

The carbon fibre tips with blue-burnt chrome detailing are the final touch — modern, motorsport-inspired, and a perfect contrast against the rear bumper. As always, everything was carefully fabricated to ensure precise fitment, smooth flow, and a factory-plus finish.

To highlight the upgrade, we’ve included before and after images — an easy way to see just how much impact a rear section and tip upgrade can make.
