Is there such a thing as a silencer for a slip-on? Because my two bros slip-on is gets annoying after like 5k rpm. Or should I just get like a new full exhaust, or would that be even louder? Maybe something like the Yoshimira because I heard they're almost like a stock exhaust? Btw anybody know where I can find a cheap full lowering kit and HID lights for cheap other than ebay?

Few questions there, can help you with the first one. There is a tip you can buy for the 2bro that will lower the dB a couple. Its not a lot but it may make it less annoying.

Power tip...

As for other exhausts, the longer the muffler the deeper and generally quieter it will be. You could go a quiet core AreaP full exhaust. Modifying the stock exhaust is another option. I would imagine the yoshi will not be that different to the 2bro, little quieter but its nowhere near stock.

A sound suppressor that lowers the noice lewel by 3 db means

you cut the noice down by half.

If you cut 6db you only got 1/4 left on noice.

Hence, 3db is alot.

Quick question, what is so annoying about the exhaust. I was planning to getting a 2bros slip on. Is it just loud or what??

 

[AngelForce]

i'm planning on getting the two bros slip on and just to be clear i don't have to jet my bike for just a slip on correct? i know that shimming the needles or jetting makes the bike run a lot better, but right now i don't have the money for the exhaust and then paying for the install of the jet kit at my dealer.

3db is nothing. Noise limitations in the states runs at 93db, so lowering it by 3 ain't shit, not even close to half the noise.

AF: You need to re-jet. Opening up the exhaust at all-all but requires a re-jet. Just shim them for a slip on... Everyone else has, including me, and you'll be fine.

+1 lol
i also just want to get a slip-on.. dont really have the $$ for dealing witht he jet/shimming right now.
but wanna be heard on the street!!

 

[gummybear]

what eric means is that its a logarithmic scale. the sound perceived sound intensity increases 10 fold every 10 db. so it will cut the output by half. see: http://en.wikipedia.org/wiki/Decibel#Examples

 

[AngelForce]

how long do you think i'll be able to run the slip on without doing anything? if i get the slip on and ride for a couple weeks with it on will it hurt anything if i don't shim or jett?

 

[Travisty]

Just take it easy on it... You'll notice if it's too lean for the bike, it either won't accelerate, or accelerate very slowly.

 

[AngelForce]

K i'll probably shimm the needles before i get the exhaust, but i was just checking. it seems like the overall conscencious is that it isn't that hard to shimm the needles. hopefully i can figure it out.

 

[spooph]

Angel Force, you probably want to do it right when you get the exhaust. The whole idea behind shimming the needles is to get a little bit more fuel into the cylinder... If your "air system" - intake, carbs, exhaust don't change, you don't necessarily HAVE to do it, nor do you HAVE to do it when you get the slip on, or for that matter, a full system. However, if you do not shim the needles with the slip on, you will notice a difference. It might worth a shot, just to feel what it feels like. You really won't hurt the bike.. Yea, ok, if you ran it hard, a little lean for a long time, then inspected the engine internals under a microscope or something, you might be able to find some pitting, but the difference is so small the engine can easily handle it...

 

[AngelForce]

k thanks spooph i'll wait until the next crappy day and attempt to shimm the needles. where would you recommend buying the washers?

 

[gummybear]

radioshack has an assorted washers package that has the right ones in it

 

[t1gawa]

... so do you have to buy a bag of random washers, then search for the few right ones??

 

[gummybear]

yea. i mean it was like a buck for a whole bag, and it came with a bunch of each size...theres prolly 50 in the bag. i think there is maybe enough of the right size washer to put about 5 on each needle. which you should NOT DO. but if a buddy needs some, they are there

 

[AngelForce]

do you guys think the carbon fiber will peel? i like the look of the carbon fiber the best

 

[gummybear]

no it wont... at least, i hope to god it wont, because im receiving my carbon yoshi full from ups tonight... :-D

why does radioshack carry washers?

 

[gummybear]

uhh... cause its stuff for small electronics projects?
