An ideal complement to the installation of high performance downpipes, this 3" / 76mm diameter Alpha Competition exhaust crossover fits without modification on the S58 engines fitted to the BMW M3 G80 / M4 G8x / M2 G87 in order to optimise exhaust airflows. Manufactured from high quality T304 stainless steel with handmade TIG welds, this crossover pipe will bring a better response time and a lower exhaust temperature.
