PROFILE


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.

Watch the video below to find out more about the differences between the X-Pipe and the H-Pipe.


ENHANCE THE SOUND OF YOUR S58

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.  


S58 Midpipe

CONSTRUCTION

The ARM S58 Midpipes are a 3" designfrom 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.



The ARM S58 Midpipes then transition to the X-Pipe or H-Pipe section of the exhaust via the slip-fit connections on either side.  Where the exhaust merges is the heart of the ARM S58 Midpipes where you have the choice between X-Pipe or H-Pipe and is where the magic happens.  The sound waves of each bank of your S58 engine are combined to produce a much more exotic and richer exhaust note. The X-Pipe or H-Pipe section lives above the OEM brace with ample clearance, there is no need to install a larger brace.
