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.

Mostly good goggles, discomfort on nose-bridge - not for big noses!
Color: Black (Black-color Lens)
It's difficult to find good quality goggles that I actually like, but these get pretty close. For context I swim every Monday before work as a workout, so there's a few aspects I look for/are important for me and these tick most of the boxes.
1) Comfort - Probably the most important factor. These are very comfortable around the eyes, the rubber is soft and they don't leave rings. My old goggles always did and walking into work with "raccoon eyes" turns heads. These don't leave rings and are still watertight. Only complaint is the plastic over the nose-bridge is angled inward, towards your nose, instead of outward away from your nose/following the line of your nose away from your face. And it's thick, so it digs into my nose. It's not a game-killer but I feel it and it's uncomfortable. It will be the thing that pushes me to try a different pair next time. If you have a "big" nose or one that curves outward from the top, I don't recommend these goggles. They will be uncomfortable for you.
2) Clarity - These are very clear and don't distort your vision underwater. They don't fog up (at least for now) and provide a wide range of vision. Good work.
3) Fitting - The strap is easy and intuitive to adjust but leaves a bit to be desired as it's a single strap around the back of your head. I like the security of 2 straps/a split strap that straddles the back of your head holding the goggles firm in place and preventing up/down movement. The good news is I haven't had issues with this yet, so it could just be a change in what I'm used to that makes no functional difference, but I'd be a little concerned to dive off a starting block as I'd worry they might release. Again, I HAVE NOT done this and I haven't had any issues, it is just a feeling. The button quick-release is a nice effortless way to pop them off when I finish and I'm tired!
4) Other - The case is a nice touch! I hate my goggles getting scratched and this helps prevent that. Nice to have.
Overall - They are comfortable around the eyes, don't leave rings, are clear & don't fog up, and functionally have been great with the quick-release & included case. They may be uncomfortable on "big" or "protruding" noses due to nose-bridge design & thickness.
4 stars because they dig into my nose a bit...and I never thought I had a funny nose but maybe I do!

Great customer support, but blurry underwater for me.
Color: Blue Hawaii
I'm a casual lap swimmer who swims 30 minutes every day. Needed some decent goggles and saw the Aegend brand was a highly rated bestseller. I first ordered the mirrored version of this lens which is essentially identical to this clear version. Was really excited to hit the pool when I received the goggles. Love the strap system on these Aegends which adjust on the back and has a quick release button...my other goggles have a little short strap that adjusts at the temple and it drives me crazy. Goggles are very comfortable and never fogged up during my swim. Nice field of view.
What's the issue then? These goggles are perfectly fine and clear above water, but blurry underwater. The blurriness is like a prism effect. My local YMCA has small tiles and with these goggles the tile lines were duplicated several times over. The effect isn't bad and perhaps some may be able to live with it, but it was annoying to me. Contacted Aegend customer service and they asked if I was myopic (no) and offered to send a replacement free of charge including a choice of couple different models. I chose instead to return the mirrored version and rebuy this clear one thinking perhaps the mirrored tint had something to do with it. Second pair of goggles arrived and same thing--clear above water and blurry underwater. Aegend says not everybody's eyeballs are built the same and again offered to replace the goggle free of charge including to their flat lens which shouldn't have the blurry prism effect. I declined since I know the strap design on their flat lens goggle would drive me crazy.
So in summary--these goggles are great and customer support is first rate. But I cannot give the goggles 5 stars since they didn't work for my eye profile and caused everything underwater to be blurry. Doesn't seem like the majority of people buying these goggles have the same issue though so I wouldn't hesitate buying them to see if they work for you.
UPDATE 2/14/17. I'm revising my review to 5-stars. Aegend once again contacted me and tried to make things right. They had another swim goggles with the clasp on the back like the one for this product but with a flat lens (https://www.amazon.com/dp/B01MTXI8SV). These new goggle work great and are clear underwater. Can't say enough about a company that stands by their products like Aegend.

Excellent Goggles — Comfortable, Secure, and No Leaks
Color: Aqua
These goggles are excellent quality and were very easy to adjust. They have good suction and fit nice and tight without being uncomfortable and stayed secure the entire time I was swimming. Not much for style, but these do look pretty cool.
I wore them for about an hour with no issues at all—they remained comfortable and didn’t leak, which is a huge plus. The seal held up well without leaving painful pressure marks.
The included case is also a great bonus and makes storage and travel easy. Overall, a very solid pair of goggles that perform exactly as expected. Definitely recommend.
