WHAT ARE MIDPIPES?
Located between the downpipe outlets and center resonator, midpipes make up roughly 12 feet of factory tubing and two large resonators. Upgrading this section removes the resonators and ultimately frees up the middle of the exhaust system improving flow and exhaust notes.
This helpful diagram splits the factory exhaust into sections as an example to simplify the system.
QUALITY CONSTRUCTION
IE midpipes are manufactured from high-quality 304 stainless steel tubing. This material is premium for exhaust systems and provides lighter weight and superior corrosion resistance. Enjoy the trouble-free and long-life operation of your exhaust system upgrade.
PERFECT FIT
This perfectly crafted exhaust upgrade exceeds even the factory fit. IE engineers take extra steps with advanced 3D scanning technology and rapid prototyping to design these exhaust parts with exacting alignments without any interference or rubbing.
RELIABLE FLEX SECTIONS
It's all in the details. Typical aftermarket flex sections found on many cheaper exhaust parts are the primary failure point, causing annoying leaks and performance issues. Our OE quality TIG-welded and liner reinforced flex sections are incredibly resilient to splitting or cracking for complete reliability.
MIDPIPE SOUND RESULTS
The S4 & S5 3.0T engine is an absolute powerhouse capable of delivering tons of power and driver enjoyment; unfortunately, the factory exhaust is full of resonators and mufflers to silence the fun. IE's midpipes are an affordable solution that modifies the stock exhaust system by removing factory resonators and replacing them with high-quality straight pipes resulting in a much-improved exhaust note.
DIAL IN YOUR EXHAUST
With IE's Midpipes and downpipe upgrades, you can replace individual sections or variations of the exhaust to dial the volume to your preference.

Gorgeous But Size Up
Color: Burgundy (Stretch Fabric), Size: Small
The suit has a beautiful, rich burgundy color — truly eye‑catching and elegant. Unfortunately, the fit was a major issue. I recommend sizing up at least one size, especially if you have fuller thighs or glutes. The pants were very tight in the thigh and buttocks area, the vest didn’t cover the lower hip area, and the jacket sleeves ran short with a tight fit in the shoulders. Overall, the small felt more like a youth small rather than an adult small.
Our set also did not include the pocket square as advertised, though it did come with a white dress shirt and a mini black tie with a matching pocket square. The material itself felt okay — not bad, but not great.
We really wanted to love this suit because the color is gorgeous, but due to the sizing inconsistencies and missing item, we couldn’t keep it.

Impressive Quality and Style – A Perfect Prom Look!
Size: Small, Color: Maroon Collar Black
I purchased the YND Men's 3-Piece Slim Fit Tuxedo Suit Set for my son's prom, and I couldn’t be more thrilled with the results. From the moment he put it on, it was clear this suit was something special. The fit was absolutely sharp and flattering, perfectly hugging the frame without being too tight — just the right balance of tailored and comfortable.
The material feels high-quality and looks even better in person — smooth, sleek, and polished. It held its shape beautifully throughout the night and gave my son a sophisticated, modern look that turned heads and earned him plenty of compliments.
You can tell this suit is well-made with great attention to detail, from the stitching to the lining. It easily rivals much more expensive brands. I’m so impressed with the value and style that I’ll definitely be purchasing from this company again.
If you're looking for a tuxedo that delivers elegance, confidence, and exceptional quality without breaking the bank — this is the one!

A Good Value
Size: Small, Color: Black, Size: Small, Color: Black
The suit is a good value. Ordered for senior prom for my son. He is 5’10 athletic build and between 165-170 lbs so we ordered the small since he wanted a slim fit and nothing that would be very loose. The suit fit him great, not too snug , the jacket has a satin finish on the lapel and edge of pockets which gives it an elevated elegant look. The jacket has an interior pocket but the rest are just for aesthetic as they do not open. I did have to cut a small slit in order to use the pocket square. The pants fit like a glove but you may want to size up if you are very muscular. The material is light weight which is perfect for prom season or warmer weather. The vest was oversized but we were not planning to use the vest anyway. Quality: several hanging threads that needed to be snipped but no big deal, the stitching was even and straight and the interior had piping of a complimentary fabric. After a full night of dancing and activities he did not have any issues with stitching breaking or splitting of seams. The buttons are black with a silver edge which give the suit some sophisticated flair but keep this in mind if you plan to style with gold. Overall, I am very pleased with this suit considering it’s price point. It’s perfect for a teen that will attend various senior events. Shipping took 2 weeks so plan accordingly and pay attention to the expected delivery date.
