Introducing the ARM Motorsports S55 Single Midpipe Upgrade for the F8X platform, the ultimate solution for S55 enthusiasts seeking to enhance the power and sound from their S55-powered BMW.Ā This S55 Midpipe upgradeĀ delivers improved exhaust flow and an incredible exhaust note due to theĀ resonated 3.5" design.

CONSTRUCTION

Its mandrel-bent tubing ensures smooth, unrestricted flow, while theĀ lightweight design of only 17lbsĀ reduces overall weight of the exhaust system by 15lbs.Ā WhenĀ paired with theĀ ARM S55 Track Exhaust,Ā 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.Ā This allows you toĀ connect the ARM S55 Midpipe to any downpipe upgrade that fits the OEM S55 Midpipe, including theĀ ARM S55 Catted Downpipes.
This section of the ARM S55 MidpipeĀ includes a 4.5" resonator toĀ tune the tone of the exhaust into a deeper, more desirable range, as the S55 is notorious for having a high-pitched, raspy exhaust note.Ā Paired with theĀ ARM S55 Catted Downpipes, the ARM S55 Midpipe will make your F8X one of the best sounding on the road.Ā Ā 
Due to the larger size of the ARM S55 Midpipe, the OEM under-brace cannot be utilized.
