The Milltek cat-back for the 308 GTi 270
The system replaces the exhaust behind the catalyst and suits 308 GTi owners who want more character from the 1.6T without touching the catalyst. It is listed for non-OPF/GPF cars only, so check your car before ordering.
Choose resonated for a quieter system with less drone on the motorway, or non-resonated for a louder, sharper sound. If you also run the smaller car, the 208 GTi has a cat-back and downpipes in our 208 GTi collection.
