PROFILE


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.



ENHANCE THE SOUND OF YOUR S58

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.  




CONSTRUCTION

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 Crossover Pipe

The ARM S58 Crossover Pipe is designed to work with ARM S58 Downpipes and ARM S58 Midpipes, but is also compatible with the OEM downpipes and midpipes or upgraded downpipes and midpipes that utilize OEM style connections.
