You guys asked for more with our New Valvetronic Designs HFD Midpipe for the BMW G8X M3/M4… now paired with our ALL NEW 400 Cell Catted Downpipes, here it is. This combo completely transforms the S58 sound, pushing it into a much higher pitch with a cleaner, sharper tone that’s way more exotic than stock. It starts to take on that raw single turbo G8X character, creeping into GTR/VQ sound under load, while still staying refined and usable when you need it. This is still in development as we continue dialing everything in. Let us know what you think down below 👇 More updates and release details on the HFD Midpipe will be shared soon. Stay tuned 🔥 Visit Valvetronic.com for all of your exhaust system needs ⚠️ #bmw #g8x #g80 #s58 #exhaust
