Strong, Reinforced, Reliable
DroneTrap
IE's advanced DroneTrap technology captures the pulse waves responsible for the V8 engine's exhaust note and draws them into dual mathematically tuned resonators. The internal ports are engineered to resonate these waves against each other in a process that selectively cancels out those responsible for annoying drone, leaving a deepened, enriched exhaust acoustic you'll love.
Complete Catback
This catback design includes all sections to replace the factory exhaust tips, mufflers, tailpipes, center pipes, X-pipes, and midpipes all the way up to the stock cats/downpipes — an entirely new exhaust system that delivers the perfected exhaust note from your 4.0T engine.
Advanced Engineering
Advanced 3D scanning tools and cutting-edge software provide IE's engineers with a high-resolution digital model of the Audi C8 RS chassis. This data is used to maximize exhaust size for flow and optimize all available space for the perfect catback fitment.
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 for superior corrosion resistance, with every joint hand TIG welded using precise fixtures and tooling — your new exhaust is built strong to last.
Stamped Muffler
The large center-mounted muffler system is wrapped in a stamped, multi-wall suitcase that reinforces the housing inside and out — protecting the muffler from warping or splitting at the welds under exhaust movement.
Reinforced Hangers
Engine movement and exhaust weight transfer stress into the exhaust hangers, putting a lot of pressure on the mount brackets. IE's catback system uses multi-point, boxed-in hanger mounts designed to stand the test of time — drive confidently knowing your exhaust is securely mounted and protected against rattles or breaks.
Bridged Piping
Sections comprised of dual 3" piping running in parallel are reinforced and bridged to offer superior strength and weight dispersion — this detail reduces stress on the welds and protects the piping from vibrations and twisting that can lead to leaks and rattles.
Reliable Flex Sections
The forward midpipe sections of the catback incorporate high-quality double-wall flex joints with the strength to remain leak-free. Enjoy your exhaust upgrade without worry, knowing the flex sections can withstand forces from even aggressive track and racing environments.
Leak-Free Clamps
Enjoy a tuned, enjoyable exhaust note without any raspy leaks ruining the show. This system assembles with wide-width stretch clamps designed to seal exhaust connections and pull them together — a clamp style popular in high-end OE applications known for long-term reliability.
Your Stereo System Is Obsolete
Hear It In Action
Sound Control
The built-in valve system retains factory drive-select button functionality in your MMI system, for control just like stock. Select Comfort to drive around your suburb like a civilized neighbor, or trigger RS/Dynamic mode to release a symphony of boosted V8 roar. Retains all RS, Dynamic, Comfort, Individual, Auto, and other drive modes.
Exhaust Valves
When cruising in Comfort mode, the twin valves remain closed, forcing all exhaust to flow into the large center-mounted muffler and dramatically reducing volume while retaining a sporty tone. Toggle your drive mode to Dynamic or RS through the stock MMI to open the valves, letting exhaust flow straight through double 3" pipes for the loudest volume possible.
Installation
Install your IE catback without any permanent modifications or installation hassles. The process is straightforward and accomplished with standard mechanic tools — an auto lift is highly recommended. Install time is around 3–4 hours.
