Guys which Exhaust is this ?

[ravenland]

Hello everyone, I'm new here to forums and new owner of a 645.

I seek advice from those who know about this exhaust... :help

Is that Hartge or Eisermann (as some people said on forums)? If none, then which one? I want a deep, growling sound, instead of high-pitch F1 one.

Thank you in advance :)

uuuuuuuuuh! You think the owner would have pressed the gas pedal a bit more...

It's shape looks like Eisemann.

I agree, but I'm just interested in that growling, low, deep sound :)
