@valvetronic: As Requested, the G8x M3/M4 HFD Experience with NO BURBLES. The Valvetronic HFD Midpipe completely reshapes the sound profile of the S58, bringing out higher frequencies, cleaning up the tone, and pushing it into something far more exotic than stock, characteristics that imitate the R35 GTR, while still keeping it usable when you need it. This setup includes: - Stock Turbos - 3" IRL DPs - Valvetronic HFD Midpipe - Valvetronic Valved Sport Axle Back Exhaust System Let us know what you think, and go secure your spot on the waitlist now on valvetronic.com!👇 #BMW #G80 #M3 #valvetronic #S58
