I'm from Belgium, the exhaust is from Skytune.
I like it because it's not ridicousely loud (or else it wouldn't be TüV approved) but sounds awesome when you floor it.
Couple a weeks ago I went to see the soccer match of Belgium Scotland.. already running too late, I dropped of my girlfriend and irresponsible took off like a maniac, I admit and don't approve it..
but..
Afterwards she told me that being over a kilometre away, she could still hear me taking off :mrgreen:
