BMW M4 Rev Battle - Hamann vs Akrapovic vs Stock

  • 5 years ago
BMW M4s with three different exhaust systems make a little noise!

Starting off with our stock Austin Yellow M4 from BMW UK, followed by the grey car with Hamann bodykit and Akrapovic exhaust before heading to the Hamann M4 Art Car with full exhaust system.

Thanks for watching, Tim
