Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Turn up the flow and sound on your Focus ST225 Mk2
Upgrade your Mk2 ST225 with a serious exhaust front section that frees up turbo flow, sharpens throttle response and delivers a richer, more aggressive soundtrack. Available as a high-flow sports catalyst or a straight-through de-cat pipe, this front section is the go-to choice for owners who want a noticeable performance uplift and a tougher tone.
Crafted in 3 inch / 76.2 mm pipework, it connects the front section to the centre/mid pipe for a direct, hassle-free fit to the standard system or most aftermarket setups. All required fittings and gaskets are included for a clean installation.
Why enthusiasts choose this upgrade
