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.

Look great for dress up up casual
Size: 13, Color: Black Leather/Optic White
I wear them every day for work. They are comfortable and light. I will say I was frustrated with the crease in the top that started the first time I wore them but other than that they are a great pair of shoes.

Hard to Beat for the Price
Size: 10 Wide, Color: Tan Leather Burnished
I purchased these for a business trip to Italy and wore them daily for the two weeks that I was there, during which I walked extensively. For me, there was a break-in period of a few days; before it loosens up, it will bite your heel, so I recommend wearing bandages or heel pads initially. Following the break-in, it's a very comfortable shoe and has served me well. I purchased a wide, and for this shoe, I found the width agreeable; in my experience, Cole Haan wide widths tend to be hit or miss (i.e., a wide is sometimes not all that wide). In terms of durability, I would not expect these to remain in good condition for more than a year if you wear them daily. The leather is not of high quality, but it's acceptable for the price. Expect them to crease very quickly if not using shoe trees. That doesn't bother me, but I know some find it objectionable. All in all, I like them and would buy them again. It's a comfortable alternative to traditional dress shoes for the office and works equally well for casual wear. Most higher quality options cost at least two or three times as much, and many are unavailable in a wide.

My favorite shoes
Size: 14 Wide, Color: White Leather
I’ve probably purchased like 40 pairs of these shoes or more. By far my favorite white sneaker. I have a large foot so the bigger sizes are appreciated. They’re versatile, literally go with anything and they are true to size. At a certain point they start to show wear and you can’t dress them up, but they last as a regular sneaker for a long time afterwards. I try to nab them on sale when they drop to $50-$70, absolute steal at that price point.
