Loud Cans...

[Steve_H...]

Interested in a little feedback on this one I have a Yoshimura R77 (Not road legal) can on my bike, pulling the clutch in everytime i get a sniff of a policeman is starting to get a little boring to say the least...

The last thing i want to do is go back to the standard Fireblade can, but that said i also dont want to be attracting too much unwanted attention.

The Law on this, from what i can find on the subject seems alittle grey to say the least ?

What is the legal Decibel level allowed on the road ?

If exceeded what punishment can we bikers expect for being naughty and exceeding it ?

Does anyone know of any nice road legal GP Style cans for a Fireblade ?

8-)

Ps... Does anyone want an almost new Yoshi R77 Race can :

its done (or used to be unless they changed it) on a WOT (wide open throttle) drive by test....

the bike is ridden at half throttle, past a stationary dB meter at one meters distance, then the throttle opened fully at the instant of passing....
think the legal dB limit was 98 (which is just louder than a mouse F*rt).......
this includes, induction roar, engine mechanical noise, aerodynamics, chain noise (which is the real reason manfr's use o-ring chains!) and exhaust noise.

how about using the baffle? is it too quiet? and too loud without it?
do you need something in-between?....

I shouldn't worry about it. By the time you've seen the cop he'd have been listening to you for at least half a mile. All those times you think you've sneaked past un-noticed was really the cop not giving a sh@t.

If 98dB is the legal limit then nearly every Harley I know of is breaking the law mine included but I have never been stopped or even questioned about my exhausts.

The police don't care about boy/girl racers in their Saxo's with aftermarket exhausts, which you can get made as loud as poosible, but they get funny about motorbikes.

When I was younger, I had a custom made Powerflow exhaust on my 206gti, along with a viper carbon induction kit, and that was alot louder than my bike can but the police used to always question the legality of the 'E' marked can on my bike.

I think the only way you can be above the law is to have an 'E' marked can, otherwise you'll start to accumulate points on your licence.

You don't need to go standard as there's plenty of noisey cans out there and Powerflow can even make one for bikes which are all 'E' marked but even they come with an advisory warning [smiley=thumbsup.gif]

ive got some laser cut stainless rivet on badges (done by a mate in a machine shop) with BSAU 193 T3 1983 on it, and the E mark in the square (cos he's clever)......

gissa shout if you want to "Procure one" they cost approximately 1 beef burger, or a portion of chips, or one pint of coke (no ice ta)... ;-)

i'l bring a few to Sally tonight....

:-)

[jonnydangerous]

can you keep the can you have and modify the "perforated baffle tube" inside, a reduction in diameter would result in a decrease in noise..... (i have perforated tube and a welder....)...... [smiley=thumbsup.gif]

It's most probably been put somewhere on the forum already, but we should be allowed to be as noisy as possible, to wake the dozy ejits driving around in their little tin boxes! [smiley=evil.gif]
And anyway, bike don't hang around for long enough to make a noise nuisance anyway

[jonnydangerous]

yeah, agree.....altho my "John Deacon Desert Race Pipe" on my KTM (valued at more than the bike was) was Juuuuuuuuust a weeeeee bit ear splittingly loud.....hahaha :-)

[Jacde]

But that's why ear plugs were invented ;D ;D
