SFC Exhaust DB-KILLER

[zizitto]

Good day to all of you...

Today for the first time in 2 and a half years my bike worked again.
It's a SF2 converted a bit like a SFC with SFC megaphone exhaust and
SF2 exhaust pipes.

Now when the engine worked for my it was fine but i think everybody in my small village will be after me with there kitchen knife(s) ...

Is there a easy-to-fit- exhaust DB killer somewhere for the short megaphone SFC exhaust.

Kind Regards Sam

sam, use the search function keywords "sfc supertrapp"

Megaphone eh?
My second SF2 had a two-into-one SFC megaphone exhaust.
What a BEAST. I loved it. I also made it a point to IDLE down my street.

@ JOTACORSA : I've checked the search function and I however the option of Marnix does work fine ( no lack of power in mid-range). I don't want to rebuild my megaphone with a supertrapp extension. Because I love the megaphone a lot like it is.

Has anybody tried to weld a DB-Killer in it? And the mid-power increase due to a Db-killer is it a lot?

Has anybody fit a Db killer like this one into a megaphone?

And how many Db does a megaphone (without a Db-killer) produce? And how many do you think it will increase with a Db-killer like the one above?

Kind Regards Sam

My SFC churns out 116 DB at 4000 revs.  Just ride fast enough, the villagers won't see you!

you sure I mean decrease or less ...

The villagers are a problem but if I want to ride it on track it also has to be less DB...

Here in Belguim they don't like noisy bikes even on track :'(...

At Zolder and Mettet open exhausts are not very welcome. Just like our Zandvoort and Assen..  :-[

Francorchamps rules!  :-*

... you can get a "noise reduced" SFC megaphone in Italy now! A friend of mine has just mounted it to his SFC replica.

"noice reduced" => "power reduced" ??

Not necessarily. Just as opening an exhaust does not mean more power in any case. F.e. if you have a modern exhaust design, you can lower the "noise" without losing power. It is all about reflection and absorbing the unwanted dB's ... 

Not sure though how it is in this particular case.

@ lavgert : where can you buy these exhausts? and of course the price is ... ?

No body fit DB-killer in megaphone???? And the HP-loss... Is it 3 HP (that only Valentino Rossi can feel it or see it on a dynamo testbank) or is it like 10 HP and a BIG F##K-feeling...
