Switchable Quad-Exit Sports Muffler Upgrade for Audi S1 8X 2.0 Turbo

Give your S1 the soundtrack it deserves with this Austrian-built rear section from Remus. Designed for the Audi A1 S1 8X 2.0 turbo petrol, it delivers a deeper, sportier note and improved gas flow while keeping day-to-day refinement. The flap is controlled by your car’s original electronics, so you keep factory functionality with a far more engaging tone when you want it.

This axle-back upgrade replaces the factory rear box with a premium, corrosion resistant steel assembly and four 102 mm outlets for an aggressive quad-exit look. It is ECE type approved for road use in the UK and EU, giving you confidence along with stunning style and sound.
