U have dyno charts? Can u post the before and after charts for everyone?

Thanks in advance!

YES, they tend to be a little loud, but that simply lets all the cagers know I am there. No problems with the police in my area.
They do sound awesome, nothing quite like it.
Is that Jess'es old bike

Well, seeing as how no one (show me the thread/owner otherwise) owns a full blown 170hp RC51, it would seem like a more economical move to build HRC clones that use smaller diameter tubes that don't cause that problem on street bikes, if what you say is true about loss power, wouldn't it?

Tom,

That would be Jess's old bike and we were turning wrenches on it a few weeks ago. It sounds mean when it's fired up.

sure does, nobody has. the way that exhaust was desigend was for a reason and makiing a replica with smaller tubing defeats its purpose and it just for looks. there are, and have been alternatives that make good power that do't kill the mid range

PM if you would like to some tips or info

Well, I had Akras before and these are (much) louder. I also had a map made. That was when Simon first had those Ti cans (3 yrs ago?), and they have been great!

No, I don't have the run sheet anymore, but it's my recommendation you get a custom map if you do run these cans for peace of mind. I haven't rode the bike in six months and cranked it the other day just to listen to for awhile... you'll enjoy them...

Default Cans.....

Ok,guys; I have tried to inquire about these "Ladybird" canisters before but never got a straight up answer??? What I want to know is (odbviously) there is NO full system or even a slip-on for the SP-1 But i have heard that universal canisters are or are not available? If so,how much each? I have a set of low-mount Sato Ti slip on system (which i'm already tired of) but will the canisters fit on the mid-pipes? What kind of gains,if any,can be expected? I have ONLY done the flapper mod and nothing else? I also noticed something different about the cans on the bike;one outlet is bigger than the other so how would that affect the performance of the bike? I am working this thing up this year and want to do a couple of different things and this might be one of them? But need these questions answered??? Thanks,guys!!! I would also love to see a pic of an SP-1 with these on it?

i can have any muffler you want made custom built to your specs including core size and muffler length and shape.

i also have a set of used ladybird ti cans cans for sale if you choose that route as well

universal cans are available.
contact Simon for details on price. he's allways been very quick to respond in my dealing with him. great guy, great seller.
yes they will fit your mids with adaptors. Tell simon what you have he'll get you the right stuff.
the difference in can diameter is a tuning thing. nothin to worry about.
what you'll gain is noise and lots of it, but it certainly is awesome to hear. it is loud make no mistake about it.
power wise the difference is negligible you wont notice any difference if you map it. I gained a little on top, but not enough to justify an omfng thread. my set up is banzai mids and Simon cans btw. running these you will lean out a touch, nuthin crazy if you have a map for your satos already but it will prolly need a little fattening up.

this statement simply is not factual.

the diameter of a muffler has nothing to do with tuning. the inner core pipe and total length have to do with tuning but a huge can only has more packing around the core pipe making it quieter but does nothing to make, or lose power in itself

ok troll, he asked about the difference in can outlet on his satos which is in fact a tuning thing. if you wanna argue semantics look up what the word means and then learn how to spell it. I'll wait a month for you to figure it out. douche bag.

does not matter what he asked, you answered with a complete false and bullshit statement, shame on you.

let's try to be factual when giving info Jared, this is a fact based think tank for the 51. you are supposedly one who knows so tossing out drivel misleading people is silly. if you have no clue as to what you are talking about try sitting back and shutting up

i simply corrected your error and a thank you would have sufficed
