BMW 420i – Rear Exhaust Section Conversion at MIJ Exhaust! 🔥

This BMW 420i came into MIJ Exhaust for a rear section conversion, transforming the factory single exit setup into a much more aggressive dual exit system. 😎

The original exhaust featured a single outlet with twin tips, which we upgraded to a full dual exit rear section, giving the car a wider, more performance-focused stance at the back.

To finish it off, we fitted single carbon fibre tips on each side, adding a premium, motorsport-inspired look that really elevates the rear styling of the car.

We’ve included before and after images so you can clearly see the transformation from the original setup to the upgraded dual exit system.

The result is a cleaner, more aggressive rear end with a deeper, sportier exhaust note to match.
