Unlock Hidden Flow Potential in Your BMW M340i G20 with Akrapovic Stainless Steel

The Akrapovic E-BM/SS/8 Evolution Link Pipe Set is the critical missing piece between your BMW M340i G20 factory mid-section and a full Akrapovic performance exhaust transformation. Developed and tested in conjunction with the Akrapovic Slip-On Line Titanium (S-BM/T/17H), the E-BM/SS/8 eliminates restrictive factory catalyst connections on non-OPF/GPF equipped M340i and M340i xDrive Touring G21 models, allowing exhaust gases to flow freely for improved throttle response and a deeper exhaust note. Precision-bent stainless steel construction ensures long-term corrosion resistance and maintains OEM-level fitment tolerances for leak-free installation on the B58 turbocharged inline-six platform.

Key Features

  • Mandrel-Bent Stainless Steel Construction – Smooth internal bends eliminate restriction and prevent turbulence for maximum exhaust velocity on the B58 engine
  • Evolution Series Design – Developed specifically to pair with Akrapovic Slip-On Line (Titanium) S-BM/T/17H for optimized back-pressure reduction and sound tuning
  • Direct Replacement for Non-OPF/GPF Models – Fits 2020+ BMW M340i G20 Sedan and M340i xDrive Touring G21 models that were not equipped with the Otto Particulate Filter
  • Precision Fitment – CNC-cut flanges match factory mounting points for leak-free installation with no modification required
  • Corrosion-Resistant Material – Stainless steel resists road salt and heat cycling for years of reliable performance
  • Non-CARB Compliant – Competition-use product for non-emissions-regulated applications; verify local regulations before purchase

Frequently Asked Questions

What is the Akrapovic E-BM/SS/8 and what does it do on the BMW M340i?

The E-BM/SS/8 is an Evolution Link Pipe Set that replaces the factory connecting pipe between the catalytic converter and muffler on non-OPF/GPF M340i G20 models. It reduces exhaust back-pressure, improves throttle response, and enhances exhaust sound when paired with the Akrapovic Slip-On Line.

Does E-BM/SS/8 require any other Akrapovic parts to work?

Yes. The E-BM/SS/8 must be ordered together with the Akrapovic Slip-On Line Titanium (S-BM/T/17H) for a complete system. It is not a standalone product for non-OPF M340i vehicles.

Does E-BM/SS/8 fit the M340i with the OPF or GPF filter?

No. The Akrapovic E-BM/SS/8 is designed exclusively for 2020-2022 BMW M340i G20 and M340i xDrive Touring G21 models that were NOT equipped with the Otto Particulate Filter (OPF/GPF). Verify your vehicle's build sheet or VIN before ordering.

Is the Akrapovic E-BM/SS/8 street legal in the United States?

No. The E-BM/SS/8 is classified as a competition and off-road use product and does not carry CARB approval or EPA street compliance certification. It is the buyer's responsibility to verify local emissions regulations before installation.

Does the E-BM/SS/8 fit the BMW M340i G20 Sedan and G21 Touring?

Yes. The Akrapovic E-BM/SS/8 fits both the M340i G20 Sedan and the M340i xDrive Touring G21 on non-OPF/GPF equipped vehicles.

What power gains can I expect from the E-BM/SS/8 link pipe?

The E-BM/SS/8 link pipe reduces back-pressure in the exhaust system, which typically contributes to improved throttle response and modest horsepower gains when paired with the matching Akrapovic Slip-On system. Exact gains depend on vehicle tune and configuration.

How long does installation of the E-BM/SS/8 take?

A professional shop can typically complete the link pipe installation in 1 to 2 hours. The process requires removing the factory mid-section and installing the new link pipe with the provided hardware and clamps.

Does Akrapovic offer a warranty on the E-BM/SS/8?

Yes. Akrapovic covers the E-BM/SS/8 with a 2-year warranty against manufacturing defects when purchased through an authorized dealer.

Installation Instructions

  1. Allow the exhaust system to cool completely before beginning work
  2. Raise the vehicle safely on jack stands or a lift and locate the factory mid-pipe connecting section
  3. Remove all factory clamps, hangers, and fasteners securing the factory link pipe
  4. Slide the Akrapovic E-BM/SS/8 link pipe into position, aligning flanges with the catalytic converter outlet
  5. Install the Akrapovic Slip-On Line S-BM/T/17H onto the link pipe outlet and attach all clamps per instructions
  6. Torque all fasteners to specification, start the vehicle, and inspect for exhaust leaks before road testing
