I wishing i could keep this for my new BMW，
but this one is for 「BMW 320 330 420 430 series」only
-full set Fi exhaust black titanium qua-tip &carbon fiber diffuser.

Paid for $8.9k intoltal . Installed 1 month ago with original receipt as proof.
If not the best bmw exhaust,it would be one the top choice for bmw exhaust.
Contact me for my own car video of what the sound is like after installing .

The original diffuser of 4 series can't fit so I purchase a carbon fiber qua-tip diffuser with it. + Downpipe
This package I'm hopping to get a price at around $4200。 cheap way to get a better and more backfire sound then M4！

message me for any different offers.
