2021 x4 m40i
Hey there,
New to bimmerpost but came across this thread after purchasing my 2021 x4 m40i.
The car currently has about 200+ miles on it and doesn't have any sort of exaggerated burps or gurgles even when it's in sport pus.
Curious if i'm missing something in regards to making the exhaust louder or having that sort of muffled backfire.
Any suggestions are appreciated.
Thanks!
