My BMW M140i Gets A New Exhaust! | Driven+

In this video, I take my BMW M140i to MoreBHP to find out whether upgrading the exhaust actually increases performance! I had a BCS midpipe fitted, and after some dyno runs, we saw a 12HP gain—proving that a simple exhaust mod can make a real difference. Massive thanks to Mike and Jason at MoreBHP for their expertise and for getting the M140i sounding and performing even better. If you’re considering an exhaust upgrade, this video might just convince you!
