F10 M5 Eisenmann exhaust + MSR intake
#3
I heard that stock OEM intakes on these car's are well engineered. But I also heard that MSR Charge Pipe's help gains. So I'm not sure what to believe! And the price is $1,300 I don't want to waste my Money for sound increase!!!

The intakes with charge pipes are more toward 3k, it sounds loud, I don't believe they will do much improvements for that price me personally I would never buy such
