Performance Exhausts

[wana]

are these point blank illegal to have fitted on your bike or is it only

that they are ilegal when/ if you are causing a noise disturbance with the sound of it ?

or is it illegal because it hasnt been tested at the DLT for emisons yet ?

or possibly that the HP has changed maske it illegal etc ?

i cant find any exact info on what laws there is or how they decide that a big roaring harley is ok

yet a d-tracker/ ksr / scooter and a loud exhaust seems to attract the cops like flies around _/_/_/_

does anyone know the legal sitaution in regards to these things ?

[CARLIN]

Don't worry about it, Nobody else does

Believe me, Harley riders with aftermarket pipes pay fines for excessive noise frequently.

[VocalNeal]

Because they can! Most drugs are transported by small bikes so any excuse!

[KRS1]

If the aftermarket exhaust has passed certification the manufacturer will provide a sticker with it. The exhaust will also have the government stamp on it verifying that it has passed.

On my previous bike i took the bike to the registration office just to see what was up with the noise level and if it would pass or if cops would harass me about it, the guy working at the government inspection station told me if it wasn't loud there would be no problem, started the bike for him to listen to and said it was good to go. He didn't mention the government certification sticker, but i brought up the issue, and he told me yes it is good to have the sticker to show to the cops just in case, so they dont have any grounds to write you a citation.

My exhaust wasn't that loud though, maybe twice of stock...whereas an Endurance or DBS would be about 5 times as loud over 4k rpm.

He also mentioned that cops in CNX mainly go after bikes with those skinny tires/wheels because they are safety hazards.

how about Tsukigi pipes from Japan ? does anyone know if they are too loud to be legal for an ER6N ? havent

heard of them beig goverment certified but i hasvent heard of many loud pipes being certified by government

Some Tsukigis are government certified I know the KRK series are certified, but they're not made in Japan theyre made in Thailand.

cool ,i thought they were japs but arai gor dai .......if there exhausts are legal ,i dont mind where it comes from ......

how do you find out if its certified or not ? i ve passed a good few police but i usually put the clutch in and roll

past them and dont hit the gas until im out of their reach but id like to know if its certified or not ......

[KRS1]

The silencer will have the certification stamped into the metal, it looks like a 4 sided diamond with a cross in the middle and will say TISI (Thai Industrial Standards Institute) on it.

FYI, Tsukigis like to break at the welds if its the sectioned style ones that have a bronze tint to them, but its usually do to a small exit hole at the silencer that uses chambered plenums and only if your driving fast and peaking the rpms constantly. A straight through silencer shouldn't cause the pipe to break though. I had 3 welds break and had to use stainless steel arc welding rods to reinforce it. No way gas or argon would have held, had to be arced.

i dont know if your familair with it or not but this is the one im using :

the somchais in the shop wanted to make it louder but i told them the low setting is plenty loud already

they said bring it back if its not loud enough and they can open it up a bit more but it turns

heads already if you give it any gas at all .....

good for the expres way when your between about to get squashed between two trucks just to let them know your there !

[KRS1]

I dont think thats a Tsukigi KRK. The KRK series look exactly like stock, but the first plenum chamber is moved back by about an inch and there's a baffle disc 1 inch away from the silencers inlet (not outlet) with holes drilled around the radius of the disc.

I dont think the one in your pic is certified, if it is there should be the TISI stamp on it.

What bike is that for? The sections look really tight.

ll try and get under the bike and check for the diamond stamp but theres not much clearance on this

If its a straight through silencer i dont think it would break, but if it were me id get all the joints arced for good measure..it

ll be ugly as hell though.

In case of emergency breakage id keep a couple of big radiator hose clamps under the seat to rejoin the sections just in case. Nothing sucks worse than it breaking when your in the middle of nowhere. I was half way to Chiang Rai via CNX when i had the first break.

I have a chamber/silencer from the Thai HRC team, the engineer told me that the metal 'HRC' plate should be removed for street use, as any HRC exhausts are banned.

Never had a problem with it yet, although I did remove the plate.

It's crazy loud, and I pass through police checks twice a day, never been fined. Or even questioned, I get moaned at for having no mirrors frequently, but they never say anything about the screaming noise that follows me around.

I'd say it's probably 10x louder than stock.

Believe me, Harley riders with aftermarket pipes pay fines for excessive noise frequently.

And rightly so. And the keyword is "aftermarket pipes", i.e. no silencer. What's wrong with these people?

Nothing wrong with them. Its all for road safety. For protection of humans and wildlife, you know. Ask Tony, he knows this topic well.

People with "silencers" are dangerous and should be forced to mount a siren that automatically switches on while driving. And the emergency vehicles should remove their sirens and switch to something louder than sirens, maybe cannon crackers

lol

you can see up close its not finished to the same standard as the likes of a yoshimura or akrapovic

but it sounds and performs excellent on the er6n ,makes it feel liked a proper bike

+ only cost 4900

fuel consumption is around 200km per 15.5L tank in the city which seems high but idle speed has dropped to 1000 rpm from 1250-1500ish before i had the can put on

i will play with the idle today and test throttle response to see if its optimal yet but thumbs up for the pipe so far

also saved a few kilos ,the stock can was WAY heaver than this one , ridiculously heavy !

Actually, I wasn't being sarcastic, as I have seen a lot worse eg: Termignoni systems.

I was a bit curious about that statement too. What do you see in the pics that make you think the Tsukigi finish isn't of good quality???

[thaicbr]

Funny enough. Tsukigi are standard on the Tiger250rs but I can not remember seeing a stamp. I don't think the Thai made lifan's have it either.

Of course everything legal with the Tiger Boxer 250. The stamp is hidden under the footpeg.

Loud Pipes Save Lives

Yes, but they also make people and animals sick and crazy. I do not think this is the way to go for enhanced road safety in future. Its a bit selfish to mount loud pipes for safety. But it is also highly understandable for riding in LOS of course.

Back home where people drive around in soundproof cars completely oblivious to what's going on around them I think the "Loud Pipes Save Lives" slogan is a crock of <deleted>.

But if you spend some time on the wild and crazy roads here in Thailand you'll quickly realize that many motorists here DO listen to what's going on around them.

I say anything that helps make you more noticeable and visible to other motorists is a good idea. It's not a panacea, but it can certainly help.

Trying to get through Bangkok traffic on a quiet bike can be really frustrating, but if you are splitting traffic on a loud bike it's quite amazing how most motorists will actually scoot over to let you pass. It also makes scooters think twice before they pull out in front of you.

I also think loud pipes are useful for getting street dogs and other wildlife off the road.

Happy Trails!

Well that explains why o never saw it. Wantan do you think your original Tiger exhaust is to loud???

Because that's about the same as most after market one's. Also that's actually the downpipe NOT the muffler. Crafty Tiger.

There seems to be some agreement that TOO QUIET can also be dangerous- case in point:

[thaicbr]

Personally I think there is a happy medium. I don't like bikes that are so loud you need ear protection just standing next to them (many choppers on straight pipes) but a nice growl is good.

that pic doesnt look too bad but when you hold it in your hand next to a yoshimura for example one looks like finer craftmanship than the other

the tsugiki does a cracking job though considering the price of it and time will tell if it lasts or not

krs1 mentioned earlier that some of them have been known to fail during use

but hopefully it wil be ok ........
