I love the RPI GTS on my M5 but there is one exhaust that I feel will BLOW everything else and thats the Valvetronic from Active Autowerks.

I love it for a few reasons
1. Turn the car into silent mode -- Runs softer than stock
2. Turn the exhaust all the way up -- Loud as it can get -- Sounds SUPERB
3. Using the tuner in the cabin tune when the exhaust will turn loud (MY FAVORITE )

So if you want the exhaust ports to open up at say 5000 RPM, then every time you hit or exceed 5k RPM the exhaust ports open up and the car sounds louder, change gear drop RPM and its soft then approach the 5K RPM and its loud again-- I LOVE THAT

Guys, small correction here, The valvetronic exhaust is made by Agency Power -

You can check out videos on you tube for sure and should have stuff on their site aswell


here is a link for their M6 -- I guess they have the same one for the M5

That is such a sweet exhaust, it needs to be experienced in person. You should talk with Dylannn23 and see if you can hear his.
