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.  Video shown below fitted with crossover, mid pipe and downpipes.

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.

The crossoverpipe is designed to work with ARM downpipes and mid pipes, but can also be fitted with OEM or other aftermarket pipes that utilises OEM connections.
