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.

Not for aggressive chewers!
Color: H) Infinity Ring, Color: H) Infinity Ring
Not for aggressive chewers! Done for in about two minutes. I unboxed this and tugged with my Mal for a but then let her have it. Within minutes she had chewed through it. Not worth the money.

Not Quite So Durable...
Color: B) Medium 3" Ball, Color: B) Medium 3" Ball
Maybe I have a SUPER aggressive chewer...he went through this ball in under a week. I originally bought the ball because of a review that stated the owner's Pitbull had the same ball for two years; not so much for my Rottweiler. He started chewing off and swallowing small crumbs from the ball within a day or two. By the end of the week, it was chunks so I had to toss it in the trash to prevent an intestinal obstruction. On the up side, my Rottweiler LOVED the ball while it lasted. However, I can't, in good conscience, give this ball a rave review based on this experience. Please take this review with a grain of salt as I have yet to find ANY toy that my boy won't DESTROY in a week or two. I hope that someone finds this informative when searching for chew toys for SUPER aggressive chewers like mine.

loud but in a good way
Size: 4.5"
Love these crazy loud squeeky balls. I bought two a bit too big but the dogs still love them. Yes, they will drive you insane but the dogs love them so much it's worth it watching the pups enjoy the balls. They are strong and safe as long as they aren't too small for your dogs mouth.
