SLN S58 Single Mid Pipe with Under-Brace - BMW G80 M3 | G82 | G83 M4 & X3M | X4M LCI Filter ZAERO Design has been makingWe are particularly proud of our unique G8X single midpipe, which was specifically designed to eliminate the highly restrictive nature of the OEM mid pipes thus creating optimal exhaust flow and drastically improving performance. The single mid pipe design also reduces the characteristically raspy noise from the S58, due to its unequal length exhaust design. The result is a far more aggressive exhaust note with more base.
