It's no secret the 3.0T engine has the makings of a true performance powerhouse, unfortunately from the factory the supercharged engine is muffled and resonated to death. In its stock state, the car is so quiet that it’s possible to forget your driving an S powered chassis altogether. That just won't do, by removing both factory resonators and replacing them with a high-quality tuned 304 65mm stainless pipes; the engine sound comes to life! If you’re a true enthusiast that loves a deep and throaty exhaust note, you will not be disappointed with your new IE 3.0T downpipe system.

Increasing the tubing size and deleting two sound muffling resonators results in noteworthy gains of 8-12 horsepower and torque (ft-lb). Larger gains may be realized on more aggressive setups such as stage 2 or stage 3 vehicles.

304 Stainless steel tubing and tig welding make for a long-lasting and worry-free product. High quality lined flex sections will never come apart internally and clog your exhaust like inferior flex sections. Especially in forced induction (supercharged or turbo), economy flex sections are bound to fail and cause performance issues.

One of the greatest features of IE downpipes is that they are a breeze to install. They can be done with minimal tools in your garage (or driveway) on jack stands. No welder or sawzall required! It’s sad that we even have to mention this, but it’s a fact that many cheaper products often require modification to be installed. For a hassle-free install, go with IE who stands behind their products.
