Rvng Designed 4” True Single Valved Exhaust System (F80 M3/F82 M4)

10/10!

This exhaust is amazing! The install was easy and straightforward. The sound quality is top notch. I’ve heard lots of F80’s but this exhaust was something different. It has such a deep tone and gives the S55 the ability to breathe. Love the fact it’s valved definitely neighbor friendly. With valves closed sounds just like stock until you press M1/M2 then it wakes up! Best purchase I’ve made for my F80 so far!
