BMW G8X M3/M4 Resonated Midpipe – Single 3.5 inch Centre Section for S58
Unlock the sound and flow your BMW G8X deserves with this high quality resonated midpipe upgrade for the S58-powered BMW M3 and M4. This two into one, 3.5 inch resonated single midpipe replaces the restrictive OPFs/GPFs and middle box, increasing exhaust flow and delivering a deeper, cleaner exhaust note without the unwanted rasp that can plague straight-through systems.
Designed specifically for the BMW G8X platform, this resonated centre section merges both banks into one 3.5 inch pipe to smooth pulses, enhance performance potential and amplify the signature S58 tone. A larger mid brace is included to prevent vibrations and keep the system rigid and rattle free.
