LEADING FEATURES
WHAT IS THE X-PIPE?
Located after the midpipes and before the catback, IE's X-pipe replaces the middle section of factory tubing and the sizeable suitcase center resonator. Upgrading this section removes the massive resonator and ultimately frees up the middle of the exhaust system improving flow and exhaust sound.
This helpful diagram splits the factory exhaust into sections as an example to simplify the system.
CROSS SECTION DESIGN
IE's X-pipe replaces the factory suitcase muffler with straight pipes that retain the center cross-section exhaust path. This design maintains the proper balance of exhaust pulses, increases exhaust gas flow, and produces a tuned exhaust sound without annoying cabin drones or rasp.

QUALITY CONSTRUCTION
The X-pipe is manufactured from CNC mandrel bent and TIG-welded high-quality 304 stainless steel tubing. This material is the high-end choice for exhaust systems for its lighter weight and superior corrosion resistance. OE-quality clamps are included to ensure no annoying leaks or performance issues. Enjoy a perfect fit and long-life enjoyment of your exhaust system upgrade.
EXACT FIT
IE engineers employ leading-edge 3D scanning and rapid prototyping technology to ensure our X-pipe provides a perfected alignment with both factory and IE upgrade parts without any interference, rubbing, rattles, or fitment issues.
X-PIPE SOUND RESULTS
The S6 & S7 V8 twin-turbo engine can produce a symphony of addicting exhaust sound with the ability to compete with even the most exotic sports cars. Unfortunately, the stock center resonator is designed to silence the 4.0TT motorsport engine to disappointingly low levels. The IE X-pipe upgrade offers an affordable exhaust modification that removes the center resonator/muffler and replaces it with a highly tuned set of precision bent pipes that join in the center to produce a truly killer exhaust note.
DIAL IN YOUR EXHAUST
With IE's available X-pipe and Midpipe upgrades, you can replace individual sections of the factory exhaust to dial in the volume and note your preference. Most C7 4.0T platform engine sound is silenced via the factory downpipes, midpipes, and center resonator. Installing variations of these three parts can deliver a mild to extreme exhaust note without touching the rear mufflers, offering a customizable upgrade path sounding as good as a traditional catback system at an affordable cost.

MIDPIPE UPGRADE
Fort those truly addicted to the V8 growl, combine your IE x-pipe upgrade with a set of IE midpipes for an even more aggressive exhaust sound.
IE S6 & S7 midpipes upgrade can be added at the time of x-pipe installation or as an additional upgrade at a later time if desired.

Our dogs hurt their mouths chewing these bones
Color: Purple & Blue
I don't do a lot of reviews because I realize many are objective opinions. However, in this case I felt it was necessary to warn others. Our dogs are aggressive chewers. Their last rubber bones (not these) which we've purchased before, and recently purchased again, were destroyed quickly. Chunks of rubber came off the ends. Since those didn't hold up like they used to, I found these harder bones hoping they would last longer. They were able to gnaw into the hard plastic within a few minutes. This created sharp edges that cut their mouths. When I saw a bit of blood on the bones, I took them away from the dogs and threw them away. I wondered why they quit chewing on them after being so excited at first. Also, these are hard enough to damage a tooth.

Pups have shown zero interest in these toys….
Color: Purple & Blue
I would agree that these are indestructible being neither of my dogs have shown any interest in these at all. At this rate they should last forever…

Durable but losses interest
Color: Purple & Blue
My dog is an aggressive chewer. She was interested in this toy while it was new, but soon after lost interest. Good news is although it took a beating it did not break or splinter. If soppy toys are disposable in your house, give it a try.

Chew toy that will last!
Color: Blue&Red Fish
Great toy for a real chewer. It's been in the house for about 5 days and the toy is still intact and the squeaker is still squeaking.
