The OEM 4.0T downpipes include large, restrictive catalysts that limit exhaust flow and reduce power output. Replacing your OEM downpipes with ARM 4.0T Downpipes eliminates these restrictions, allowing for improved exhaust flow and performance gains.
OEM downpipes also have a crossover design, forcing exhaust gases through long, convoluted pathways with multiple sharp turns. ARM 4.0T Downpipes streamline this process by maintaining a same-side design, significantly improving airflow, reducing turbo lag, and enhancing throttle response.
-
Gain up to 37whp / 42wtq
-
Faster Turbo Spool
-
Improved Exhaust Note
-
Fully Reversible
Premium Construction
The ARM 4.0T Downpipes are constructed from SS304 stainless steel, ensuring exceptional durability and long-lasting performance for your Audi 4.0T.
-
Collector Design: Features a robust 4.4" x 3" collector welded to an OEM-style 5-bolt flange, compatible with all 4.0T turbocharger upgrades.
-
Flex Section: Built-in stainless steel flex sections absorb stress during aggressive driving, including hard acceleration, braking, and cornering.
-
OEM Mounting Points: Designed to integrate seamlessly with OEM transmission mounting brackets for added security and stability.
-
Flange Transition: Smooth transition to a 2.25" 3-bolt flange ensures compatibility with both OEM midpipes and ARM 4.0T Midpipes.
Enhanced Exhaust Sound
For enthusiasts looking to further amplify their exhaust tone, the ARM 4.0T Midpipes make an excellent pairing with the downpipes.
OEM midpipes include dual resonators to suppress sound, which may not appeal to performance-focused drivers. Upgrading to ARM Midpipes delivers a richer, more aggressive exhaust note. Installing these midpipes alongside the downpipes requires just an additional 10 minutes, making it a quick and easy enhancement.
