Technical Specifications and Benefits

The ARM S58 Single Midpipe is meticulously crafted to ensure a perfect fit and optimal performance. It starts with an OEM-style 2-Bolt flange, which can be paired with both OEM downpipes and upgraded downpipes for the G80 M3/M4. The midpipe transitions to a 4.5" diameter, optimizing sound and flow, before merging back to the OEM muffler section. This design allows for full use of the OEM exhaust valves, giving you the freedom to control the exhaust tone. Additional features include axle back adapters, ARM downpipe gaskets, and an extended brace for added support and stability. This comprehensive kit is tailored to enhance both the sound and appearance of your BMW.

Practical Applications and Target Audience

The ARM S58 4.5" Single Midpipe is the perfect choice for car enthusiasts and performance drivers seeking an upgrade that combines sound, style, and functionality. This midpipe is designed for off-road use only and is ideal for those who want to make a statement with their vehicle while enjoying the benefits of improved performance. By removing secondary catalysts and resonators, this midpipe delivers a deeper, richer exhaust note and a noticeable increase in volume. Whether you're looking to enhance your daily driver or customize your racing vehicle, the ARM S58 Single Midpipe is the ideal solution.
