INTEGRATED ENGINEERING AUDI 3.0T B8 B8.5 8R PERFORMANCE DOWNPIPES (S4, S5, Q5 & SQ5)

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.


 

 


Features

  • Deleting two resonators creates a deep and assertive exhaust note
  • Horsepower gains of 8-12 HP
  • Constructed from 304 stainless steel 2.5 inch (65mm) diameter tubing
  • Easy to install - do it at home with minimal tools
  • Tig welded, high quality, and long lasting
  • Fully lined flex section - will never collapse and supercharger approved
  • Includes all hardware and clamps needed for a hassle-free install

What Are Downpipes?

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 3.0T, the downpipes are located after the catalysts and before the center muffler. Due to the copious amount of exhaust on these chassis, refer to the 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.

Power gains measured stock downpipes vs. IE downpipes on a Stage 2 Dual Pulley tuned B8.5 S4. No changes except downpipes were made between comparison runs.

Quality Construction

304 Stainless steel tubing and tig welding make for a long-lasting and worry-free product.

Especially in forced induction (supercharged or turbo), economy flex sections are bound to fail and cause performance issues.
