PROFILE

Introducing the ARM Motorsports S55 Single Midpipe Upgrade for the F8X platform, the solution for S55 enthusiasts seeking to enhance the power and sound from their S55-powered BMW.

CONSTRUCTION

When paired with the ARM S55 Track Exhaust, you shave an incredible 40lbs off compared to the OEM exhaust system. The ARM S55 Single Midpipe starts at the downpipe connections with a precision Y-pipe. This allows you to connect the ARM S55 Midpipe to any downpipe upgrade that fits the OEM S55 Midpipe, including the ARM S55 Downpipes. Paired with the ARM S55 Downpipes, the ARM S55 Midpipe will make your F8X one of the best sounding on the road. The next section of the ARM S55 Midpipe Upgrade transitions again to a Y-pipe, which allows you to reconnect your OEM muffler. Due to the larger size of the ARM S55 Midpipe, the OEM under-brace cannot be utilized. To address this, the ARM S55 Midpipe includes a specially designed under-brace that is specifically engineered to fit with the larger midpipe.

IN THE BOX

• ARM S55 Midpipe
• CNC Machined Brace
• 5x Exhaust Clamps

FITMENT GUIDE

The ARM S55 Midpipe Upgrade will fit any downpipes that connect to the OEM midpipes.
