HEAR IT IN ACTION

AGGRESSIVE, REFINED, SOPHISTICATED

IE's advanced DroneTrap technology captures the pulse waves responsible for your engine's exhaust note and draws them into a mathematically tuned resonator. The internal port is engineered to resonate these waves against each other in a process that selectively cancels out those responsible for annoying drones. The remaining waves produce the deep and enriched exhaust acoustics enthusiasts love.

 

COMPLETE TRUE CATBACK

IE's SQ5 catback includes all sections to replace the factory tailpipes, mufflers, resonators, and midpipes up to the downpipe. Enjoy an entirely new exhaust system that delivers an instant and perfect balance of flow and harmonics to your Audi S-class SUV.


DESIGN DETAILS

STRONG, REINFORCED, RELIABLE

ADVANCED ENGINEERING

Advanced 3D scanning tools and cutting-edge software provide our engineers with a high-resolution digital model of the SQ5 chassis. This data is then used to optimize the exhaust design for flow and performance utilizing all available space for the perfect catback design.

TIG WELDED T304L STAINLESS STEEL

A quality catback needs to sound remarkable AND stand the test of time. All piping is constructed of mandrel-bent T304L stainless steel to offer superior corrosion resistance. All joints are expertly TIG welded by hand using precise fixtures and tooling. We take great pride in knowing your new exhaust was built strong to last.

 

STAMPED CENTER RESONATOR

The magic of IE's center resonator doesn't end with our internal DroneTrap technology. The entire system is wrapped up in our stamped multi-wall housing. These design details reinforce the resonator housing inside and out and protect it from warping or splitting at the welds under normal exhaust movement.

RELIABLE FLEX SECTIONS

The forward midpipe sections of our catback incorporate high-quality double-wall flex joints with the strength to remain leak-free. Enjoy your exhaust upgrade without worry, knowing your flex sections can withstand forces from even aggressive track and racing environments.

REINFORCED HANGERS

Engine movement and exhaust weight are transferred into the exhaust hangers, which puts a lot of stress on the mount brackets. IE's catback system is manufactured with multi-point and boxed-in hanger mounts that will hold your exhaust securely in place without any annoying rattles or breaks.  

BRIDGED PIPING

Parallel sections of the rear catback are reinforced and bridged to offer superior strength and weight dispersion. This minor detail works hard to reduce stress on the welds and protect the piping from vibrations and twisting that can lead to leaks and rattles.

LEAK-FREE CLAMPS

There are no thin-sided finicky exhaust clamps found here. The entire exhaust system assembles with our wide-width stretch clamps designed to seal your exhaust connections and pull them together. This style of clamp design is used in numerous high-end OE applications and is known for long-term reliability.

INSTALL GUIDE

Install your IE catback without any permanent modifications or installation hassles. The installation process is straightforward and accomplished with standard mechanic tools. An auto-lift is highly recommended.

Install time around 2-3 hours

Excellent Product

I was surprised with the quality of the exhaust. I was unsure I would like the way it made my SQ5 sound. But I’m in love with the way it sounds especially in sport mode. It sounds like a sports car and it’s not obnoxiously loud. It’s perfect! I definitely recommend and I’m looking forward to purchasing more mods for my vehicle.

IE=QUALITY!!!

Great experience from start to finish. First off, easy to order and fast shipping. Then received it well packaged, everything was packed with great care to ensure product integrity was intact. It was on overall easy install, and would recommend doing the downpipe at the same time if you got the money, but for me I did the exhaust only. Would definitely like to purchase the downpipe in the future, as their products are very well engineered, hence the name. One tip on the install of the driver side, you need to tilt the pipe and tighten to get it to clear the rear brace. Quality on the exhaust and welds are top notch, can't say enough about the quality. Recently purchased the intake and inlet as well and together a perfect symphony of sound. Really elevates the driving experience, and take it to another level. So do yourself a favor and pickup something, anything from Integrated Engineering. Everything they make is great, but exhaust is must!

The Exhaust YOUR B9/B9.5 Needs RIGHT NOW!

If you're on the hunt for more turbo noise or a louder exhaust note than what your stock exhaust offers, look no further than the IE Catback for the Audi B9/B9.5 SQ5. Constructed from T304-L stainless steel, this exhaust system not only promises longevity, but it also eliminates the problematic single valve on the driver's side that often fails.

Designed to fit flawlessly onto the Audi B9/B9.5 SQ5 without any need for modifications, upgrading to the IE Catback is a hassle-free process. I can personally attest to this. The exhaust system delivers a deeper and more aggressive sound, lending a sporty and improved exhaust tone to my B9 SQ5. The turbo noises are also amplified depending on the turbo setup.

Installation of the exhaust system is relatively easy, and the high-quality construction ensures improved sound and enhanced performance. As an Audi enthusiast, I can confidently say that the IE Catback exhaust system is a worthy investment that delivers on its promises.

I’m trying real hard to like this exhaust. It drones a bit and the mid section sits on the cross member and rattles.
