BMW America is offering new M Performance exhaust system for the E92 and E93 BMW M3 which as you can confirm with the video above sounds great. That is overkill really, because the standard M3’s V8 does sound quite awesome. Still, it’s nice to make it more aggressive, specially as the new system also enhance the performance by optimizing flow and reducing pressure. What’s more the new exhausts are 20lb lighter than the standard unit. It’s all good, but the price of this M Performance exhaust is achingly high at $4,374!
