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.

Midpipe upgrade

Absolutely fantastic quality, welds are fantastic! The install process was not as bad as many people claim. With a little creativity and 2 people we had the old midpipes out and the new ones back in, in an hour and a half . Adds a really nice tone to the exhaust note. I would highly recommend the install!

Perfect

These midpipes just woke my S4 up!! Sounds great, added some much needed girth to the tone. I also have a CTS high flow cat. I recommend this product especially if you were thinking of getting a full catback system. Easy install and a literal bang for your buck. The only hard part is the backwards nuts on the DP.

Sound great!

What a great addition to my S5 couple. They could great. I added the transmission mount since I was already under the car and an upgraded dump valve. I drove though a parking garage this morning and this thing sounds like Ferrari.

Install was challenging. Mostly the dreaded down pipe nuts. Creativity is needed. Highly suggest a short, ratchet, wobble wrench. The right side is easier to access from underneath. I don’t suggest trying to remove the V clamp from the down pipe. The heat had mine pretty much welded on and trying to pry off most likely would have damaged it. I found it wasn’t necessary to remove.

It took way longer than 2 hours for me, but I’m also not a master mechanic. Nonetheless, happy with the purchase!
