Hello i am Heiko from Germany,

i have Supertrapp 3 " with internal Disc system by Supertrapp / Kess Tech!

For a better sound i use 20 Disc on every side .

My question is : Why is my sound not so loud and so deep like a Supertrapp from USA?

MY BIKE IS A 98 EVO FAT BOY

THANK YOU

HEIKO

You most likely have "quiet cores", which meet European sound requirements.

The "quiet cores" can be replaced with "performance cores".
