Installing a high flow catback exhaust is a quick way to pick up horsepower and torque. A catback exhaust will also give your Audi B8 S4 3.0T 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 2.37" 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: Quad 100mm, Quad 80mm, Polished or Black Cerakote. Dual Black Cerakote Ovals.

A little Flimsy
Love the texture and look of this frame but it doesn’t hold its shape very well and requires actual screws to secure the backing. One of my screw fasteners was broken off the frame in shipping so maybe that’s why it isn’t as tight as it should be but I was hoping for a more secure fit. A LOT of flex and wobble.

Great shelf for price!

Great shelf for price. VERY easy to install. We put one side of screws of metal bracket in studs to make it sturdy & stable. This was KEY! Follow simple drawing dictions and you can’t go wrong! Was Leary about some bad reviews but we had no issues. Came quickly with no flaws. Looks great and is very light, but is stable when put into bracket correctly. Size is beautiful with the thickness & depth of upscale shelf. If you want a nice shelf that doesn’t break the bank- get it. This one worked well for us!
