Milltek Sport Exhausts

Swifts offer a comprehensive selection of Performance exhausts from Milltek Sport which build on the successes of key marques like Audi, Volkswagen and BMW. Performance that blows your mind, not your ears!

Milltek have 21 Years of continuous exhaust development and technical expertise are drawn upon to develop the ultimate Milltek Sport range of performance products.

This has placed Milltek Sport at the forefront of tuning companies and owners ‘must have’ list. Swifts are an appointed key distributor for all Milltek products.

Milltek Sport Exhausts

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.

Power, Sound, Awesome Looks
Milltek stainless steel systems have a genuine performance edge - power gains around 10%, sounds that are truly awesome, looks that are subtle but sexy and a feeling of true exhilaration.

Comprehensive Range
Already Audi, BMW, Porsche and VW owners are enthusing over the power boost, acoustic performance and stunning looks of their high performance Milltek Sport exhaust systems.

Quality Materials
Confidence in our engineering expertise, and our selection of the highest quality materials ensures that all our customers select a Milltek Sport system, confident they have purchased the ultimate sports exhaust.

Continuos Development
Milltek products are developed for worldwide distribution, rigorously tested on the rolling road and through many miles of subjective analysis. Milltek Sport look at tailpipe styling, ease of fitment, vehicle specifications and power variances to only deliver quality, responsibly engineered products. Recent additions to the range include the New BMW M3 and Porsche 996 Turbo.

Milltek Sport don’t just develop systems for petrol engined vehicles either, recently the BMW 330D system was developed giving a useful performance increase and greatly improved ‘spool up’ of the engine due to the larger pipe diameters and reduced back pressure. Under development for release in the near future are performance exhausts for the new breed of performance 4 wheel drive vehicles, the BMW X5 range, Porsche Cayenne Turbo and VW Touareg.

Milltek Sport Hi-flow Sports Cats

Your original catalytic converter will typically have 400 or 600 cells per square inch (cpsi), these original cats are restrictive in their flow, typically allowing an open area of around 55-65%.

A Milltek Sport Hi-flow Sports Cat which will be fully integrated into a large bore downpipe, has only 100-200 cpsi depending on application. These cats have an open area of between 75-85%, thus reducing back pressure substantially and increasing flow rates, all very desirable for extracting more performance, especially on turbocharged engines. Emission levels are maintained at legal limits by careful selection of the volume of the metallic substrate. Lamda probe positions remain unchanged from the original equipment.

Milltek Sport Hi-flow Sports Cats work exceptionally well on re-mapped (chip tuned) engines. Click here for an example of the power and torque gains that can be achieved.

Milltek Sport Hi-flow Sports Cats are made from a special stainless steel containing aluminium (called ‘Fecralloy’). This material was developed in England in the 1970’s specifically to provide resistance to oxidation at very high temperatures.

The material is used as a very thin strip (2 thousandths of an inch) and is coiled together to make a honeycomb structure. Because the metal strip is so thin, the honeycomb has a very low flow-obstruction. To reduce the flow-obstruction even further, the honeycomb is made with 100 or 200 ‘cells’ (i.e. channels) per square inch compared with 400 or 600 per square inch for a standard catalyst.

The result is that about 85% of the total cross-section is open. The honeycomb is held together by using a special nickel-based brazing material which is applied in a vacuum. The finished honeycomb is then coated with Aluminum Oxide, some rare earth metals and Platinum and Rhodium. The Platinum and Rhodium are applied at a rate of 25 grams per cubic foot, which compares with between 5 and 10 grams per cubic foot for typical US aftermarket items.

It is normal practice in Europe to use much higher quantities of precious metals on catalysts, because European gasoline has more impurities in it which gradually poison catalysts. If catalysts with such high levels of precious metals are used with US fuels, the post-catalyst emissions are extremely low and the durability of the catalysts is very good indeed.
