Service Completed: Full Custom Exhaust System

This Seat Leon FR came in for the full performance treatment: a custom turbo downpipe, midbox delete, and a bespoke valved rear section.
We built the valved rear box to sit horizontally for maximum flow and a clean OEM+ fit, finishing it off with aggressive quad tips to complete the transformation.
With the valves closed, the FR remains smooth and subtle for daily driving. Open them up, and the car comes alive—unleashing a sharper, louder, turbo-fed roar packed with character and attitude.
