Milltek Secondary Cat-Back Toyota Corolla GR 1.6T 2023-2025, Resonated, Quad GT115 + 100 Titanium

Milltek Sport exhaust system for Toyota Corolla GR

Replacing the factory exhaust with a Milltek Sport system brings back the character that the Toyota Corolla GR's engine holds back from the factory: a rounder tone at idle that opens up cleanly through the rev range, with no artificial effects.

Frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the system remains unobtrusive at steady cruising speed, ideal for daily driving.
• What about the neighbors in the morning? The valves operate as on the factory system: closed and quiet on startup or in comfort mode, fully open in sport mode.
• Installation: fitting requires cutting the factory exhaust. We recommend having it fitted by a professional.

Why choose Milltek Sport?

A reference among European tuners, Milltek Sport develops each of its systems directly on the vehicle. Mandrel bends, careful welds and aerospace-grade stainless steel make for a system that lasts and sounds right.
