POWER GAINS

Installing the IE 3" catted downpipe on your B9 A4, A5, or Allroad 2.0T engine, you can expect huge power gains of +20-25HP when installed with a Stage 2 ECU tune or plug-in tuning box (this can vary by brand). *Power figures are on full bolt-on and tuned Stage 2 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.

HIGH-FLOW CATALYTIC CONVERTER

IE’s performance downpipe includes a high-flow 200 cell per inch metal matrix catalyst located as close to the turbo as possible. Metal matrix catalysts are higher performance because the matrix web is thinner, allowing higher flow in the same size. Our catalyst is also a very large diameter, allowing a large flow area and maximum power. By being placed close to the turbo, emissions and unwanted unpleasant smells are greatly reduced

DIRECT BOLT-ON DOWNPIPE WITH PERFECT FIT

The IE downpipe replaces over 6 feet of restrictive factory exhaust tubing, all the way back to the OE "Cat Back" rear section. Sturdy fabricated mounts and precise engineering result in a rattle free and long last replacement exhaust system. 3D scanning systems were employed to ensure perfect placement both in pre and post production phases.

About Integrated Engineering: Merging decades of experience with hundreds of hours of prototyping, engineering, dyno testing and daily usage evaluation has output exhaust systems that are the ultimate compliment to your performance car. IE products are proudly engineered, designed, and manufactured in-house, in Salt Lake City USA.

Runs Small
Size: X-Large, Color: Black_a
I own several embroidered Western shirts by known manufacturers, including one purchased on Amazon. All are XL, and they fit fine. So I ordered XL on this shirt. I can wear it, but it's not a good fit or very comfortable. Specifically, it is a very slim cut - much slimmer than the dimensions given in the description state. So if you are a slim guy, no problem - order your usual size. If you are stocky, as I am, go up a size. In every other way, I really love the shirt - beautiful embroidery, very nicely made. I love the contrasting colors inside the collar and placket (inside of the snaps). I have re-ordered in XXL and hope and think this will fit fine. Not to figure out how to return this from the Philippines....
