BMW G80 M3 / G82 M4 / G87 M2 S58 Rvng HydroFlow 5" Downpipes

Rvng HydroFlow downpipes use a hydroformed 5" inlet section for the S58 in the G80 M3, G82 / G83 M4 and G87 M2.

Why you need it

Most S58 downpipes are 3" or 3.5". Rvng's 5" inlet has about 104% more flow area than a 3.5" pipe right where pressure is highest after the turbo, and the hydroformed body smooths the transition. Rvng measured +15.7 hp and +18.3 lb-ft over 3.5" inlet downpipes on a stock tune.
