Milltek Center Resonator Bypass – Audi SQ5 B9 (2018–2023)

Center resonator delete / bypass pipe. Requires cutting the factory exhaust. Verify fitment by part number before ordering.

Overview

This listing is for the Milltek Sport Center Resonator Bypass for the Audi SQ5 (B9, 2018–2023). It replaces the factory center resonator section to increase exhaust presence and sharpen the tone while keeping a clean, OEM-style layout.

Brand: Milltek Sport Part No: MSAU842 System No: SSXAU1054 Pipe Diameter: 2.50" (63.50mm)
Important Installation Note
This resonator bypass requires the OE exhaust to be cut. If you are unsure about compatibility or your current exhaust configuration, message us your VIN and a quick photo of your center section so we can confirm before you order.
Key Features
  • Center resonator delete / bypass section for a more aggressive exhaust note
  • 2.50" (63.50mm) pipework to maintain strong flow and factory-like routing
  • Ideal pairing with stock rear mufflers or an upgraded cat-back system
  • Professional install recommended due to required cutting of the OE exhaust

Original Product Notes

If you want your SQ5 to sound like it should from the factory, the Milltek Center Resonator Bypass is one of the cleanest upgrades you can do. It removes the center resonator to bring out more of the turbo V6 character without changing the rest of the system. This is a great option if you want more sound without jumping straight to a full cat-back.

Milltek’s been building exhausts for over 40 years and it shows.
We put one on our Project Audi TT and the fitment was dead-on perfect.
They ship out next business day from their US warehouse, so if you’ve got a VW, Audi, or BMW, this is the setup I’d recommend without hesitation.
