B9 2.0T DOWNPIPE FEATURES:
UNLOCK STAGE 2 FOR YOUR B8 2.0T:
Equipping your B8 A4 or A5 2.0T engine with an IE catted downpipe delivers additional horsepower, torque, and responsiveness when paired with a required stage 2 ECU tune. These significant power gains are added through the entire RPM band by allowing the turbocharger to flow freely through the 3" downpipe, high-flow catalytic converter, and mid-pipe. Careful tuning of the added sound from freeing up exhaust flow rewards you with an aggressive exhaust growl every time you accelerate while minimizing cabin drone.
All IE exhaust systems are designed in-house using state of the art digital scanning for a perfect fit and manufactured from 1/16” thick wall 304 stainless steel offering a lifetime of performance and fun.
HIGH-FLOW CATALYTIC CONVERTER (CAT):
IE’s performance downpipe includes a high-flow 200 cell per inch catalyst located as close to the turbo as possible. Our large diameter CATs allow a very large flow area and do not limit maximum power. Enjoy all the benefits and performance of a "catless" race downpipe but with reduced emissions output and no unpleasant smells.
BOLT-ON INSTALLATION:
The IE downpipe replaces the factory restrictive downpipe and midpipe exhaust tubing and connects to the OE cat-back/muffler section. Precisely manufactured mounting results in a rattle free and life long downpipe system. IE engineers utilize 3D scans of the engine bay and chassis to ensure perfect placement and an easy install.
Installation should be completed by a professional and preferably on an auto lift. CLICK HERE to view and download the install guide.

Perfect for casual wear and dressy style
Color: Dark Green, Size: Small
This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.

Love the long sleeves!!!
Color: White, Size: Small
Love it! I'm 5' 11" tall and I purchased this according to reviews. Several people commented on the length of the sleeves. I have a hard time finding sleeves long enough if it's not " tall" sized. It was perfect for me. If this washes nice I'm going to consider purchasing more in other colors. I ordered the white and just love the long ribbed cuffs with the line of buttons. Very soft.
