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.

Good Quality overall. Pants need work.
Size: 4X-Large, Color: Black
I'm 6'0. 305 lbs and have a beer belly. The 4xl jacket fit like a glove. The vest on the other hand is hard to button and I can't use it. The pants, as expected are a few inches too long and a bit baggy from the knee to the butt and I will have to have them altered. I will say the pants cannot be pulled up too far as the crotch area is very shallow. I wish there were just a bit more room there to pull the pants over my belly. The overall quality is 3.8 out of 5.

Expectations Exceeded by Far

Never thought I could get a suit that fit like it was tailored right out of the box. The measurements provided were spot on. Not only was I impressed with the fit, but the quality as well. I would buy this suit several times over. I'm absolutely pleased with my purchase.
