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.

DOWNPIPE UPGRADE

Adding IE midpipes to your stock exhaust system is perfect for daily drivers looking for a noticeably increased exhaust note without attracting too much attention. Combine your IE Midpipes with an IE Downpipe upgrade for a more aggressive motorsport sound, and let that turbocharged V6 scream!

IE Downpipe requires Stage 2 ECU tuning. No changes in tuning are required for midpipes only.

I could be a foot model now!!!
Size: 1 pair black L
I wear work boots almost all of the time so I bought these to put on my feet with salycylic acid to moisturize and try to get rid of a stubborn corn on the ball of my foot. It helped drastically after a few nights of lounging in the house with them on.

Nail Must Have💅🏽
I didn’t know I needed a double-sided nail mat until I owned one—and now I’m emotionally attached. This thing has officially become my manicure bodyguard, standing between my nails and the chaos of real life. One side catches polish drips like a champ, the other side keeps my tools from sliding away like they’re trying to escape responsibility. No more nail polish on the table, the couch, or my soul. Clean-up is so easy it almost feels suspicious. It lays flat, stays put, and makes me feel like a professional nail tech even though I’m painting my nails while watching TV and questioning my life choices. Bonus points for being reusable, washable, and silently judging me for painting my nails “just one more coat.” Five stars for saving my furniture, my sanity, and my dignity. If you do your nails at home, this mat is the real MVP. 💅✨

As described
This was a gift for our niece. She loves to paint her nails, and we noticed similar mats at the nail salon we go to - so we got her an age appropriate nail "studio" to gift along with it. My friend thought it would be great for laying out when coloring and painting also, because its large.
