Description
Unleash the full potential of your Audi B9 S4 or S5’s turbocharged V6 with the Integrated Engineering (IE) Midpipe Exhaust Upgrade. This precision-engineered exhaust component replaces the factory midpipes and bulky resonators with a high-flow, TIG-welded stainless steel system. The result? A more aggressive exhaust note, improved flow, and a lightweight, durable upgrade built to perform.
Key Features:
-
Deletes Factory Resonators for a deeper, more aggressive exhaust tone
-
Mandrel-Bent 304 Stainless Steel construction for superior corrosion resistance
-
Reinforced OE-Quality Flex Sections for long-term durability
-
CNC-Machined Mounting Brackets with integrated rear stud for simple alignment
-
Includes All Hardware & Leak-Free Clamps for a straightforward installation
-
Direct Bolt-In Fitment with no cutting or welding required
-
63.5mm Outer Diameter / 60.25mm Inner Diameter Tubing
What Are Midpipes?
Midpipes are located between the downpipes and the center resonator. On the B9 S4 and S5 3.0T models, this section consists of restrictive tubing and dual resonators designed to mute sound. IE’s Midpipe Upgrade replaces this section with straight-through tubing to increase flow and amplify your engine’s natural tone, making your daily drive or weekend cruise far more engaging.
Premium Stainless Steel Construction
IE midpipes are crafted from TIG-welded 304 stainless steel—a material known for its lightweight strength and resistance to corrosion. Whether on the street or track, these pipes are built to last for years of performance and enjoyment.
Engineered for a Perfect Fit
Precision 3D scanning and in-house prototyping ensure a factory-like fitment with zero rattles or clearance issues. Integrated rear mounting studs and reinforced brackets make for a quick, secure, and worry-free installation—even with minimal tools.
Durable OE-Quality Flex Sections
Unlike many lower-grade exhaust components, IE’s midpipes feature liner-reinforced, TIG-welded flex joints. These provide the necessary movement while maintaining structural integrity under thermal and mechanical stress—preventing cracking, leaks, or premature failure.
Unlock the Sound of the 3.0T
The factory exhaust on the Audi B9 S4 & S5 is overly muffled by design. Upgrading to IE’s midpipes removes these barriers, delivering a noticeable increase in volume and clarity. Expect a more engaging exhaust note—sporty, refined, and completely free of drone.
