Installing a high flow catback exhaust is a quick way to pick up horsepower and torque. A catback exhaust will also give your Audi B6 S4 4.2L V8 a sportier tone. All Milltek catback exhaust systems feature a bolt-on design and mate seamlessly with your factory or most aftermarket downpipes.

The resonated catback exhaust features a center resonator and rear muffler producing a more refined and quieter exhaust tone while the non-resonated systems incorporate only a rear muffler and provide a louder more aggressive tone compared to the resonated systems.

Milltek Sport exhausts are produced in high quality type-304 aircraft grade in dual 2.25" stainless steel tubing. 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.

Available Tips: Dual 100mm Polished Tips in two styles, GT100 and 100mm Jet.

Authentic
Color: Black, Color: Black
This machine is amazing. We just returned from Italy and this is as close to a cafe as you can get. It leaves a dense foam on top from the high pressure water system making truly authentic. It is easy to use and clean!! I loved the size too as it fits perfectly on our shelf. Highly recommend if you want an italian cafe to enjoy!

Bargain Espresso Machine Works Great
Color: Silver
Great espresso machine, and a bargain at only $100! Pulls perfect shots with a generous amount of crema. And, it comes with a high-quality tamper. Tips: When you first turn it on, remember to run the steam wand for a couple seconds to prime the system. Test/experiment with the grind to get it just right--40 seconds with my blade grinder is working for me.

Great Espresso Machine for Beginners
Color: Silver
Update: Milk teamer doesn't deliver the foam like at the first couple of days, and the espresso doesn't come with the crema any longer. Somehow the pressure goes above the espresso range, and I tried to decrease the amount of coffee, and no results. I am so disappointed. First thing that impressed me about this little espresso machine is how easy it to use. You can make a double espresso shot in literarily 1 minute. Second thing is size, the machine is pretty compact that you can place it anywhere in the kitchen without worrying about taking too much space. Also, it heats up quick, and the options are straightforward. The water tank is just the perfect size, which is excellent for me, and I don't have to refill water constantly. Performance-wise, it feels solid and does an excellent job making shots like what you'd expect in a cafe. The water pressure is just right, delivering this espresso shot without the extra acidity. The flowmeter regulates the water evenly which is great in making that creamy espresso. Something else to note, it's small and also quiet, which is big to me since the last one was making unnecessary noise every time I make a shot. Now, the milk frother is pretty decent, and create that foam you'd love to see in your cappuccino and latte. Overall, this is a pretty decent choice, and feels durable.
