ARM 3" Midpipes for Audi B9 S4/S5

Overview

The ARM B9 Midpipes utilize an industry-leading 3" design throughout 93% of the midpipe section, compared to the standard 2.3" (60mm) size used by most other aftermarket options. The ARM B9 3.0T 3" Midpipes will unlock a more exciting and aggressive exhaust note on your 3.0T powered B9, with a fully reversible bolt-on solution, no cutting or modification required!

By removing the OEM front resonators which mute your Audi's 3.0T engine, the ARM B9 3.0T Midpipes utilize 3" piping to turn up the volume and give you a deeper, richer exhaust note. When paired with the ARM B9 3.0T Downpipe it truly transforms the sound of your 3.0T powered B9. The ARM B9 3.0T Midpipes retain the use of the OEM exhaust valves, so you can be incognito in comfort mode, or roar in dynamic!

The OEM Front Midpipes have a resonator on each midpipe that mutes the otherwise crisp exhaust note of the EA839 engine found in the B9 S4/S5. The ARM B9 3.0T Midpipes not only remove this OEM resonator, but also expand the piping from the OEM size of 2.3" up to a 30% larger 3" design, improving the exhaust harmonics for a deeper and more aggressive tone.

Unlock the full potential of your 3.0T setup by pairing the ARM B9 Downpipe with the ARM B9 3" Midpipes. On their own, each gives you a boost in power and sound, but if you're looking to get the most out of your B9 setup, pairing them together will perform and sound incredible. These two parts replace the biggest restrictions in the stock B9 exhaust setup, helping your turbo spool faster, your exhaust flow more freely, and your car sound much more aggressive—all while retaining your factory exhaust valves. Built to fit perfectly and work in sync, the ARM B9 Downpipe and Midpipes combination delivers the ideal setup for your EA839.
