BMW G80 M3 G82 M4 S58 4-Inch Hydroformed MaxFlow Downpipes

IRL 4 inch hydroformed downpipes for the BMW G8X relieve the back pressure of the stock catalytic converters so your turbos spool faster and reach peak power.

Why you need it

IRL states that a tuned S58 can see a 30 hp boost with stock turbos. A flex pipe section reduces strain and vibration, and smooth bends keep airflow optimal.
