HIGHLIGHTS
• Faster Turbo Spool
• Exotic Exhaust Sound
PROFILE
The ARM S58 Downpipes increase power and torque on your S58-powered BMW while unleashing exotic sounds from your tailpipes. The ARM S58 downpipes are one of, if not the best all around hardware upgrades for the G8X platform. The ARM S58 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.
By reducing backpressure on your S58's turbos, you are able to spool faster and hit target boost quicker. The outcome is more power sooner, resulting in faster 0-60 and 1/4 miles times. If you are planning to tune your S58, this will benefit your G8X even more, as the backpressure will increase on S58's running higher than OEM boost. Making the ARM S58 downpipes one of the greatest all-around investments for your G8X.
ENHANCE THE SOUND OF YOUR S58
CONSTRUCTION
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.
Each downpipe utilizes either a Catless Resonator, or a 200-Cell High-Flow Catalyst. The standard version is the Catless Resonated option. If you select the Catless Resonated S58 Downpipes, your downpipes will have our resonators installed to help tune the tone of your S58 for a strong and aggressive sound while maximizing exhaust flow. The resonators are completely hollow on the inside, there is no obstruction whatsoever.
If you select the catted S58 Downpipes, the catalysts will replace the resonators found in the the catless/resonated downpipes. The catted version sounds very similar to the catless variant, but will help with some of the exhaust odor. The catted S58 downpipes will likely still produce a CEL. To remove a CEL you will need a tune or a CEL Delete Kit. 
The longer downpipe (front downpipe) in the set utilizes a reinforced flex section. The flex section is incorporated into the long downpipe to relieve stress on the turbo during aggressive driving.
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.
