AUDI RS3/TTRS ULTRA FLOW TITANIUM EXHAUST SYSTEM

Engineered with uncompromising motorsport intent, tight packaging, and extreme weight reduction.
The Harrys Euro ULTRA FLOW Titanium Exhaust System is precision-crafted from 3-inch and 2.5-inch titanium, featuring a single-pass, 5-cylinder-specific tuned driver-side muffler and a valved passenger-side outlet for maximum flow and control.

At just 10kg total system weight, ULTRA FLOW delivers dramatic weight savings over factory and stainless systems, lowering rear mass, improving throttle response, and sharpening overall vehicle balance—exactly where performance gains matter most.

ULTRA FLOW retains full OEM valve integration, obeying ECU commands via throttle input, engine speed, Drive Select modes, and the factory exhaust control button.
Quiet when required—valve closed for cold starts and street driving.
Relentless when unleashed—open the valve in Dynamic mode and the system delivers a raw, motorsport-derived Harrys Euro sound, with aggressive RS-style crackles and a hard-edged 5-cylinder scream under load.

Designed for drivers who demand more, ULTRA FLOW is track-upgrade ready, with a dedicated Harrys Euro Conversion Kit available for those pushing even further.

The Harrys Euro ULTRA FLOW Titanium Exhaust for the 8V RS3 is finished with 180mm RS-style Gloss Black oval tips and is available in:

• Raw Titanium – lightweight, industrial motorsport finish

• Burnt Titanium – heat-treated blue/purple gradients for an aggressive race aesthetic

Each system is stamped with the Harrys Euro mark—ultra-lightweight, corrosion-resistant, and built with true motorsport intent.
