Remus Resonated GPF-back for SEAT Leon Cupra 2.0 TSI 5F | Quad 76 mm Chrome Outlets | 70 mm System

Give your Mk3 Leon Cupra 5F the soundtrack and presence it deserves with this Austrian-made resonated rear section from Remus. Built entirely from stainless steel with a shot-blasted finish, this GPF-back replacement unlocks a deeper, motorsport-inspired note while remaining calm on long journeys. The quad 76 mm straight cut polished tips fill the rear valance perfectly for a purposeful factory-plus look.

We have supplied and fitted this system for many Cupra owners and the feedback has been consistently positive. Fitment is precise, the tone is rich without annoying cabin drone, and throttle response feels sharper thanks to the free-flowing 70 mm pipework.
