IE's Catback Exhaust System for your Audi B9/B9.5 SQ5 features our DroneTrap technology to release the maximum sound potential without any annoying drone. Our passion for design shines with cutting-edge engineering and manufacturing techniques, mandrel-bent, stainless steel, TIG welding, and multi-point reinforcements to deliver an aggressive and refined exhaust note from the turbo six-cylinder engine.
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.
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.
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.
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.
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.
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.
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.
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.
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 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.

Other Availability Modes

We update our catalog daily to provide the most accurate fitment information possible. When shopping for parts, please use the “select your vehicle” car selector on the home page. Once you've selected your car, you can filter parts specific to it.
Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.
Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".
A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.
"MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
