It replaces the factory downpipe with a larger-bore pipe and removes the catalytic converter entirely, clearing the single most restrictive point in the exhaust for the biggest flow gain available at this position in the system. It's usually fitted alongside a Stage 2 remap, since the ECU needs to be told to expect the different readings the lambda sensors give once the cat's gone. It's offered in versions to suit the factory or a Milltek system, so you can pick the setup that suits how the car's used.\u003c\/p\u003e\n\u003cp\u003eIt's built for owners already committed to a serious power upgrade rather than a casual bolt-on, so pair it with the matching Milltek cat-back system for the full effect.\u003c\/p\u003e\n\u003cp\u003eBecause it removes the cat, it's intended for off-road and competition use.
