About us

Milltek Sport

The Pedigree

More than 30 years of continuous exhaust development and technical expertise are drawn upon to develop the ultimate Milltek Sport range of performance products, offering an ever-expanding comprehensive selection of performance exhausts which build on the successes of key marques like Audi, Volkswagen, Porsche, BMW and Nissan. This has placed Milltek Sport at the forefront of tuning companies and owners ‘must have’ list.

Milltek Sport has appointed key distributors and is currently exporting to more than 80 countries around the world.

Milltek Sport exhausts are produced in high quality type-304 aircraft grade stainless steel. This material is anti-magnetic (other manufacturers’ stainless steel may not be) and is less susceptible to discolouration. This quality of stainless steel is used on all pipework and the total construction of the silencer. Mandrel bending ensures full flow bends for better gas flow and Milltek systems are increased in bore to ensure ultimate performance without the loss of mid-range torque.

All Milltek exhausts are designed, developed and manufactured in-house in the UK. Milltek Sport, an ISO 9001 quality-approved manufacturer, have now gained EC type-approval for many of their products.

Milltek Sport has links with a number of race teams throughout the world (such as the British Touring Car Championship, Time Attack and the Volkswagen Racing Cup), supplying them with prototype designs for testing in highly demanding circumstances.

Roadrunner Motorsport


Specialists in after-market performance car and motorbike exhausts

Roadrunner Motorsport are UK and worldwide mail order specialists, with over 30 years experience in the trade. Established in 1986, we are a dedicated family business with an excellent reputation for good service, enabling us to progress to one of the UK’s leading performance exhaust retailers.

Unlike many other aftermarket retailers, our motorsport heritage runs in the blood with three generations competing in local stage rallying events. We currently run a modern Escort MK2 with a Smith and Jones engine 330BHP, a Tractive 6 speed sequential gearbox with Geartronics paddle shift.

Previous to this we ran an ex-works Subaru Impreza Prodrive formerly rallied by Kenneth Eriksson with the number plate N555 WRC. These 555 Group A Imprezas became famous after Colin McRae won the 1995 World Rally Championship in his.

Before the Impreza, we rallied classics such as a Metro 6R4 2500, an Escort Cosworth, a TR7 V8 and Escort MK1. We also ran an Escort MK2 with a BDG engine, previously owned by Bertie Fisher with the famous CIL 999 number plate. We won the Dukeries Rally with this car in 1990, the last MK2 Escort to win this particular event.

Our background in motorsport ensures our experienced staff are knowledgeable and passionate not only in our products, but also in the latest developments in the performance exhaust market. We pride ourselves on customer service and excellent communication.

Our many years of experience have led us to stock only the best quality brand names in the aftermarket motorsport industry including Milltek Sport Exhausts, Scorpion Exhausts and Cobra Sport Exhausts. We run our business from retail premises, so you can choose to collect your goods or have them delivered. We send goods worldwide daily, to countries including Australia, North and South America and Europe.

If you have any questions feel free to telephone, and our staff will be pleased to speak to you.

We hope you have a pleasant experience with Roadrunner Motorsport and will trust us with your business for many years to come.
