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.

Worth every penny

Works great! I have a van and it took all the noise out of the rear doors. I am almost in shock at how quiet it is now.

Great for what it does but not a miracle
Style: 30 sqft
Sticks well. Definitely thicker and nicer than the Kilmat version. If I were buying again I would just buy more of this, the value is better even though you get less total coverage per pack. Can be cut to size easily, we used a box cutter which got a little gummed but but not too bad. we were able to get it in and around everywhere we needed to put it and it held up well as we were mashing it into weird spots. It doesnt smell hardly at all while being applied and once its on there is no smell whatsoever The product is great for what it is. 4 stars only because I think it gets oversold for how much this alone can do. We did notice a slight reduction in noise but nowhere near the multiple decibels we see claimed everywhere. If your vehicle is mostly quiet but just has that little bit getting through this will probably do wonders, If you have a vehicle where there's significant engine noise in the cabin you'll need more than just this to bring that down.

Great product!

I can say this product makes a huge difference with road noise and is cleaner and easy to work with when applying compared to other mats that cost about the same price.

Very heavy and thick
Style: 30 sqft
I purchased mini brands of sound ending and this is by far the heaviest sound deadening I've ever ordered. I'm not installed yet but I have a good feeling that is going to work exceptionally in blocking sound. If weight is a concern for you I would recommend a lighter product however if sound quality and a quiet ride is your priority this is the one for you.
