S58 Downpipes The ARM S58 Resonated Downpipes increase power and torque on your S58-powered BMW while unleashing exotic sounds from your tailpipes. The ARM S58 Resonated Downpipes are one of, if not the best all around hardware upgrades for the G8X platform. The ARM S58 Resonated Downpipes improve throttle-response throughout the RPM range while stepping up the exhaust note, all without the need to replace the entire catback system on your S58. Both ARM S58 Downpipes then transition to a 2.75" 2-Bolt connection to secure seamlessly to the OEM S58 midpipes, or any aftermarket midpipes that connects to the OEM downpipes. The ARM S58 Downpipes are built with SS304 stainless steel and backed by the ARM Motorsports Lifetime Warranty. The ARM S58 Downpipes starts with a 3" diameter precision CNC machined turbo v-band flange. S58 CROSSOVER PIPE The ARM S58 Crossover Pipe is designed to replace the restrictive OEM S58 crossover pipe with a fully round design to improve exhaust flow. The ARM S58 Crossover Pipe retains a round form, eradicating the turbulence and constraints of the OEM oval design. Upgrading your S58 with the ARM Crossover Pipe results in increased exhaust flow for your G80/G82 BMW. The ARM S58 Crossover Pipe removes the extra casting material and sound deadening of the OEM S58 crossover pipe, allowing an increase in sound your S58 produces. The G82 M4 in the video below is equipped with the ARM S58 Midpipe, S58 Crossover Pipe, and ARM S58 Downpipes, providing an increase in volume over the OEM setup. Pairing the ARM S58 Midpipes with the ARM S58 Downpipes will increase the overall volume of your S58 significantly more than the ARM S58 Crossover Pipe alone. The ARM S58 Crossover Pipe is built with SS304 stainless steel and is completely round. The ARM S58 Crossover Pipe starts at the end of the left downpipe utilizing and OEM style 2 bolt flange and crosses over the underbody to the driver side midpipe connection. The flange on the midpipe side of the ARM S58 Crossover Pipe is designed to accommodate the midpipe gasket perfectly. S58 INTAKE SYSTEM The ARM S58 Intake will make your G8X BMW sound amazing while providing unrestricted airflow to your S58's turbochargers. The ARM S58 Intake delivers the shortest distance possible between the high-flow filters and the turbos. Coupled with the largest turbo inlet piping available, and you have the ultimate performance-oriented intake solution for your S58-powered BMW! The ARM S58 Intake utilizes extra-large 3.5" turbo inlets made from 6-Layer reinforced high-temperature silicone. The high-flow multimedia air filters are inverted to provide more filter surface area than standard conical air filters. The total surface area of the ARM S58 Air Filters is 145 cu. in. each, making the total combined surface area of both filters 290 cu. in. Instead of crudely connecting to the turbo snout, like many other S58 intake systems, the ARM S58 Intake connects to the turbos utilizing our CNC machined S58 turbo adapters. These turbo adapters are designed in-house to allow for an OEM-like fit and finish that exceeds the quality of the OEM plastic connections. The ARM turbo adapters are secured to the turbos using the OEM C-clip, allowing them to be easily installed and removed. Each turbo adapter is designed independently to fit the different sized OEM turbos on the S58. S58 4.5" MIDPIPE The ARM S58 4.5" Single Midpipe upgrade is designed to unleash the incredible exhaust sounds from your G8X M3/M4. By removing the secondary catalysts and two middle resonators, the ARM S58 Single Midpipe substantially improves the sound of your S58-powered BMW. Also, by retaining the OEM muffler, you still have the ability to control the exhaust valves, allowing you to close them for a more subtle tone for when you want to be quiet, or open the valves for maximum sound. The ARM S58 4.5" Single Midpipe will not only increase the overall volume of your exhaust but also transform the sound into something truly unique from an ordinary G80 M3. It will also make the exhaust burbles more audible even with OEM tuning. The G82 M4 in the video below is equipped with both the ARM S58 Single Midpipe and ARM S58 Downpipes. Pairing the ARM S58 Single Midpipe with the ARM S58 Downpipes will increase the overall volume of your S58 even more than the S58 Single Midpipe alone. The ARM S58 Midpipe is a 4.5" design from the downpipe connection all the way to the rear section where it will reduce to 2.75" to perfectly connect to the OEM muffler section. The ARM S58 Single Midpipe starts with an OEM-style 2-Bolt flange which can mate up to either the OEM downpipes, or upgraded downpipes that fit the OEM exhaust. These flanges will accommodate the OEM midpipe gasket perfectly. S58 MIDPIPES X-PIPE/H-PIPE The ARM S58 Midpipe upgrade is designed to unleash the incredible exhaust sounds from your G80 M3/M4. By removing the secondary catalysts and two middle resonators, the ARM S58 Midpipes substantially improve the sound of your S58 powered BMW. Also, by retaining the OEM muffler, you still have the ability to control the exhaust flaps, allowing you to close them for a more subtle tone for when you want to be quiet, or open the valves for maximum sound. The ARM S58 Midpipes will not only increase the overall volume of your exhaust but also transform the sound into something truly unique from an ordinary G80 M3. It will also make the exhaust burbles more audible even with OEM tuning. The G82 M4 in the video below is equipped with both the ARM S58 Midpipes and ARM S58 Downpipes. Pairing the ARM S58 Midpipes with the ARM S58 Downpipes will increase the overall volume of your S58 even more than the S58 Midpipes alone. The ARM S58 Midpipes are a 3" design from the downpipe connection all the way to the rear section where it will reduce to 2.75" to perfectly connect to the OEM muffler section. The ARM S58 Midpipes start with a OEM-style 2-Bolt flange which can mate up to either the OEM downpipes, or upgraded downpipes that fit the OEM exhaust. These flanges will accommodate the OEM midpipe gasket perfectly. Alternatively, you can choose to upgrade your S58's crossover pipe with the ARM S58 Crossover Pipe. The optional ARM S58 Crossover Pipe replaces the heavy OEM pipe to open up more sound and saves an additional 4lbs. S58 Exhaust Tips The ARM G80 M3 Exhaust Tips give your G8X a stunning and aggressive look that installs in less than 10 minutes. The oversized 112mm G80 M3 Exhaust Tips dwarf the smaller OEM exhaust tips on the M3 to give your G80 a more pronounced and upgraded exhaust appearance. The ARM G80 M3 Exhaust Tips are the largest exhaust tips that will fit the OEM muffler without contacting each other. ARM G80 M3 Exhaust Tips are a direct replacement for the OEM M3 exhaust tips and do not require any trimming or welding. They are secured using a single hex bolt which minimizes any unsightly extra clamps or hardware to give your G-Series M3 or M4 a clean and seamless look. The ARM G80 M3 Exhaust Tips have an 82mm inside diameter which allows them to connect to the either the standard or competition OEM exhaust mufflers. The ARM G80 M3 Exhaust tips fit the OEM rear diffuser and almost all aftermarket diffusers.
