Product Overview

Downpipes are a popular and easy mod to install. As a pair, they replace roughly 12 feet of factory tubing and a pair of resonators. This frees up the exhaust system, making the engine sound as it should. On the B8 S4, the downpipes are located after the catalysts and before the center muffler. Due to a copious amount of exhaust on the B8 S4 we have made the following diagram to simplify the system.

Power Gains

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.

 

Sound Tuning

From the factory the B8 S4 is muffled and resonated to death. In its stock state the car is so quiet that it’s possible to forget about the performance minded 3.0T powerplant. By removing the two resonators 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!

 

Quality Construction

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.

 

Direct Bolt-On With Perfect Fitment

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.

 

Power Results

*Power figures are on IE dual pulley and tuned S4 cars. Power measured at the hub performed on a hub dynamometer, power figures are taken from multiple vehicles. Power gains may differ from advertised as individual vehicles will vary in maintenance, mileage, and conditions. HP=horsepower, TQ= Torque ft-lbs.
