Description
Overview
The AWE Tuning Performance Mid Pipe transforms the exhaust system on your 2018-2023 BMW M5 Sedan (4.4 AWD) by replacing the restrictive factory mid section with a purpose-built 3″ stainless steel X-pipe. Engineered as a direct upgrade that mates to the factory Axle Back, this performance exhaust component is designed to improve exhaust flow and sound character while retaining the flexibility to build out a complete performance exhaust system on your terms.
Constructed from premium T304L Stainless Steel, this exhaust pipe is built to withstand the heat, pressure, and corrosion that come with hard driving. The 3 inch exhaust pipe X-pipe design promotes efficient scavenging across both banks, helping your M5’s 4.4-liter engine breathe more freely through a true 3 exhaust pipe layout.
Key Benefits
Unlike many aftermarket exhaust parts, this mid pipe requires no tune to install and carries a No CEL Guarantee, so you won’t be chasing check-engine lights after the upgrade. It’s also backed by a Fit Guarantee and includes the necessary hardware, making it a clean, confidence-inspiring addition to your build. With a Voluntary Label rating of 50 State Legal, it’s an exhaust upgrade you can run with peace of mind.

Modular by Design
Equipping the Performance Mid Pipes with intentions to add another section later? That’s a good thing. AWE engineered the Exhaust Suite for the M5 as a completely modular configuration, so you can build your custom exhaust one stage at a time. Start with the Performance Mid Pipe or an Axle Back now, then add the desired configuration whenever you’re ready, and roar away. This flexibility makes it easy to plan a full performance exhaust system without committing to everything up front.
Fitment
This exhaust pipe is engineered specifically for the 2018-2023 BMW M5 Sedan with the 4.4 engine and AWD. Please note an important fitment detail: pairing AWE’s Performance Mid Pipes to the factory exhaust will require cutting the factory mid pipe. Because it’s designed to mate to the factory Axle Back, installation preserves your factory tail pipe setup while unlocking the performance and flow benefits of the upgraded mid section.
Whether you’re searching for a PE exhaust, weighing performance exhaust systems, or just comparing exhaust pipes for your M5, this AWE Tuning Mid Pipe delivers proven engineering, premium materials, and a modular path forward for your build.
