Please note:
Meisterschaft products are being offered in following 4 levels:
1. MST Touring Sport performance
2. MST Touring High performance
3. MST GT-Racing performance
4. MST GT2 Label Racing performance
Previously, we had a customers who thought Meist GT units being little too loud and Touring Sport being too quite/soft.
So, GTHAUS is now offering the "Touring HP" version to satisfy the specific clients who want: Sound very similar to Touring Sport version when the motor is kept lower RPM range, But will sound close to "Meist GT" when you go W.O.T.
Also, we have recently started to offer "GT2" label unit for those who have not had enough of GT sound.

GT2 has louder and meaner sound even compared to GT version. It tends to have even higher screaming pitch noise as well as more volume tone when it is under load / higher RPM. GT2 is the meanest and loudest exhaust set up you can purchase for your M cars.
(GT2 Label units are offered only for E60 M5, E39 M5, E63/64 M6 and E92/92 M3)
