i heard it personally, it sounds great! not loud either, just a nice bearable rumble.

 

Sounds really nice, I have heard a Z they don't sound the same at all the Z has more high reving sound to it while the scram has a thump... Its kinda hard to explain, over all they don't sound the same at all.. The Z400 i heard had the stock pipe...

 

i have a nice thump at idle and when i get on it,it screams like a bat outta he77


gotta love that 4stroke thumper sound(i like 2 strokes too,particularly the 'Shee on duals)
