🔧 Service Completed: Mid Box Delete & Back Box Delete Exhaust Upgrade

At MIJ Exhaust Ltd, we recently carried out a custom exhaust upgrade on this SEAT Leon FR 2014 1.8L Turbocharged Petrol, giving it a more engaging exhaust note while retaining the practicality and comfort expected from an everyday performance hatchback.

For this build, we fabricated and installed a custom mid box delete and back box delete, allowing the turbocharged 1.8L engine to breathe more freely and produce a deeper, sportier exhaust note. The new setup delivers increased presence under acceleration with a more responsive sound, while remaining comfortable for daily driving and motorway cruising.

The upgrade enhances the Leon FR’s sporty character without compromising its clean, factory-inspired appearance, making it a popular choice for owners looking to enjoy more of the engine’s natural tone.

As with all of our custom exhaust work, every component was fabricated and installed in-house using high-quality materials and precision craftsmanship to ensure excellent fitment, durability, and a professional finish throughout.

We’ve got a full video of the completed installation along with a sound demonstration, so you can see the finished system and hear exactly how this SEAT Leon FR now sounds.

Check out the video and let us know what you think of this Leon FR transformation.
