NEW Valvetronic BMW M4 Exhaust SOUND + Install | Before and After 

gawd that sounds like it should have been from the factory all along! Love it!!

Sick that’s how that car should sound

Man those headlights n that diffuser , the whole setup is stunning

im about to order one for my 2017 c43 amg im hoping it sounds great

stainless steel is the way is you’re chasing sound on an s55, titanium makes a tinny sound that exacerbates the natural rasp of the s55

Sounds great man!!! What brand\type of High flow catted downpipes do you have and does it throw any codes?? Also are you able to pass inspection?? Im considering getting this setup but need to know first what im to expect. Final question can I get the same (similar) sound without having to do the downpipes?? Thanks

Wouldnt the titanium bring back some rasp vs the stainless? Or is it vice versa

hey what’s the name of that diffuser?

Needs a resonator imo, otherwise it sounds good

How much would you charge to install this setup? I wanna get this done to my m4 as well!

Damn, that's nice

What headlights are those?

Hello, I have a question for you. Did you buy the M4 GTS headlights in black or did you buy them in red and had them coated with black window film?

Sounds insane! Do you have stock downpipes?

amazing

What headlights are those

So you can't use the stock valve system? By switching from efficient to sport and sport+

whats the wheel fitment ???

intake?

How did you guys recalibrate the exhaust valve actuators? Or did you have to?

where did you get the front headlight?

is there any rasp at all around 2k rpm?
