The original Evo system (including the FQ range) uses 2.5" downpipe and 2.5" system, this isn't ideal for the kind of performance available, in steps Milltek!
Ultimate performance just got closer.
This is an absolute must for the serious performance seeker.
Utilising a 3" downpipe and 100CPSI cat assembly, a 3" centre resonator, 3" rear silencer assembly with a 4" custom tip the Milltek system shows big improvements with the engine boosting earlier, spooling up quicker and a lightening throttle response.
The full system comprises a front pipe, a high-flow cat, a center section and a rear silencer.
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%.
The Milltek Sport Hi-flow Sports Cat is fully integrated into a large bore downpipe and 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.
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.
Milltek are designers and manufacturers of high quality stainless steel sports exhaust systems, manifolds and catalytic converters.
Enjoy the exhilaration that Milltek stainless steel systems give you with a genuine power gain of 8-10%.
Many sports systems have a characteristic drone and boom - not so the Milltek. A Milltek system will ensure that you have the power and the looks but the sounds stay outside.
