BMW E26 M1 Procar | Hollow sound with silenced exhaust

Most M1 Procars have a very loud open exhaust which I prefer. But sometimes they change to a silenced exhaust when there are noise limits. Those exhausts also sound very nice and produce a sound similar to old F1 cars. 00:00 intro 00:08 on track 01:11 pits 01:34 on track Filmed with Canon Legria HF M46 DM-100 microphone Canon Legria HF G40 DM-100 microphone Related video My pictures Follow me on Facebook, Instagram and Twitter bmw #m1procar #bmwm1procar --------------------------------------------------------- keywords --------------------------------------------------------- loud engine exhaust sound idle revs revving car automobile racecar downshift downshifting canon legria hf g40 DM-E1 dme1 mic microphone motorsport autosport auto car cars vehicle 1979 1980 1981 bmw e26 m1 procar 2023 2022 2021 2020 2019 2018 2017 spa Francorchamps Nürburgring flames backfire flaming fire oldtimer gp grand prix classic historic summer monza
