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.

So far my dog hasn’t destroyed it! And it’s been a month. So I call that a win. Plus he loves it.

Great play and chew toy!
Pattern Name: Star
The dogs love these!
They're sturdy and give them plenty of chew time. The size is great and they are very playable. The dogs have a lot of fun and the weight is just enough for our little dogs.

Great Dane Tested and Approved 5 Star
Pattern Name: Checkered, Pattern Name: Checkered
A picture is worth a thousand words applies to this product, as you will see in the attached photos these stand up to the abuse of a Great Dane. He has dragged me around the yard for hours already with this in his mouth and the stretchy handle keeps it shape.
This ball is a little firmer than others of these I have had in the past, which helps exercise his giant jaw. I could get a few weeks out of the other brands I have bought. This brand is still like new well past the time others have failed. I will be ordering more as my French Mastiff is interested in one of his own (the boys do not like to share toys - most dog guardians understand).

Holding up well.
Pattern Name: Checkered
Seems to be holding up to my aggressive chewer. I have it hanging from a tree branch and she loves leaping to get it! Buying another pair so she has a greater selection around the backyard.
