This is our new Gen II exhaust system designed for both the E60 M5 and E63 M6. Our system is made of Dual 3" T304 Stainless from the headers back and is tig welded and assembled in house. Each exhaust system is test fitted before it leaves the facility to ensure factory OEM fitment. The system consists of dual ASR resonators, ASR X-pipe, and ASR mufflers with dual 92mm tips. It not only differs from the Gen I because of piping diameter, but also improved performance and sound quality. We will be offering a group buy of our new Gen II system upon release within the next 2-3 weeks. We will post up close pics of the system within the next 24 hours and video of the E60 M5 version shortly thereafter.
