Milltek Sport Performance Catback Exhaust System - Audi 8V RS3 2.5T
This is a special order item. Please feel free to contact us for the latest ETA.
The latest version of Audi's premier hot hatch, the 8V RS3, remains one of the most capable performance cars on sale today. Immense, near 400bhp levels of performance are paired with classic, sure-footed Quattro handling, all wrapped up in a typically refined and understated body. It's a compelling mix and one that's enabled the RS3 to find countless thousands of homes, but there's always room for improvement – hence the expansion of the Milltek range to accommodate it.
Milltek's latest exhaust offering for the 8V generation can be specified in the firm's customary, open-ended manner, giving buyers the freedom design the system best suited to their requirements. It begins with a choice of core systems, either a large-bore downpipe and de-cat (a product intended for the race/track market), or a large bore downpipe and high-flow sports cat. Milltek also offers a further option, one aimed at those buyers seeking to enhance both the sound and performance of their RS3, a secondary catalyst bypass. It fits both OE and Milltek cat-back systems.
The Milltek Sport range opens with a duo of non-resonated cat-back options. While still completely legal to use on the road, non-resonated systems will be significantly louder than those mentioned below, able to emit a suitably aggressive exhaust note. Both options consist of a front silencer bypass, a rear silencer with HollowTek Technology (one which re-purposes the OE electronic valves), electronic valve motors, wiring adaptors, a pair of trim connecting pipes, and a choice of oval twin tail pipe options; Cerakote black or polished.
Those RS3 owners seeking a quieter, less raucous exhaust note would be well advised to consider Milltek Sport's other cat-back options, both of which are resonated. Again, the two options consist of beautifully designed and manufactured exhaust components, namely a front silencer assembly, a rear silencer with HollowTek Technology (one which re-purposes the OE electronic valves), electronic valve motors, wiring adaptors, a pair of trim connecting pipes, and the tail pipe options outlined above.
Obviously the Audi RS3 is a highly desirable, wonderfully designed and manufactured car, one that demands that any aftermarket product bolted to it be at least as well engineered as the OE equivalent, and the Milltek Sport cat-back exhaust more than delivers in this respect. Not only is it made from high grade steel and to exhaustive standards, the Milltek silencer delete system has been proven to offer subtle increases in both power and torque, plus a soundtrack that really does need to be witnessed to be fully appreciated!
Constantly striving to build the best exhaust systems technically possible has resulted in a number of Milltek firsts and breakthroughs, with one of the most notable being their HollowTek manufacturing technique. This involves the careful placement of shaped silencer casings, reflection plates and varying lengths of solid and perforated internal tubing, all designed to create special chambers within the silencer itself that cancel out resonant frequencies and drone while driving at speed.
HollowTek ensures that no additional under-hang is visible beneath the system, reduces overall weight, permits the use of smaller boxes, results in a deeper sound, and enhances the pops and crackles that characterise the over-run sound of vehicles fitted with electronic exhaust valve control modules.
