open pipes?

Actually, he wasnt kidding about the aspirin. It will be loud enough to give you a headache in about 20 minutes and your ears will still be ringing an hour after you've stopped and taken off your helmet.

E.

if its going to be that loud then i am going to have to come up with some money real fast..... lol
 
I have found that the larger the displacement the lower the tone and then the more distance from the exhaust port the less annoying, That is probably why the smaller displacement 650 was crazy loud and the 1100 was loud but tolerable.
 
I think part of that is also the fact that I didnt take the megaphone off.......I just took the baffle out of it.

In all reality it wasnt loud at all at an idle, in fact it sounded very cool idling. Even if I accelerated very softly and short shifted it wasnt all that bad. It was just accelerating hard and running at highway speeds that gave me a splitting headache.

And yes I believe you are right about the displacement having something to do with it. I have a buddy that has a 1300+cc kawasaki drag bike that is open header and it is defanitly loud but it is a much lower pitch than my 650 so it is tolerable and actually sounds very mean. My smaller bike has a really high pitch tinny sound to it and I think that is what kills me vs an open header small block chevy.

Anyway, the only real way to know if it bugs you is to try it out and see. Just MAKE SURE you tune the carbs correctly so that you dont kill the poor engine.

Have fun and good luck
 
No, loud was when I put headers on my smallblock V-8 at home then drove across town with them wide open at the collectors to the muffler shop to get the rest of the exhaust fabbed. That was interesting. Ahh the highschool years... ;-)


The sound of a Chev V8 in a Sprintcar - nothing like it!
Hearing twenty four of them thunder into turn one when the lights go green - PRICELESS!!!

There's good loud and there's bad loud -

Good Loud - an old Ducati or Guzzi with a 'sporty' exhaust - like an Angel singing.
Bad Loud - a Harley with open pipes blasting through suburbia - like a cat being rubbed against a cheese grater.

To me all louds are bad, especially from motorcycles. I'm out.
 
Man that brings back memories!!! I did the same thing with my 350 camaro! The starter got so hot I had to crawl underneath and start it with a screwdriver till I got my pipes on.Ohh to be young again :-)

Hey my story was about a 350 in a Camaro (1976), too! Cut my teeth on mechanicin' on that car. It was still pretty loud after the "Muffler Man" made up the 2.5" dual with glasspacks. Every once in a while I'd unbolt the collectors, wire the exhaust up to the frame to keep it from dragging, and take a drive. The look on people's faces when you pulled up slowly next to them on the freeway then HAMMERED the throttle was priceless. Was so loud and deep you could feel it thumping against your chest.
 
Running just an open header can melt your exhasut cam and valves. At the very least scab a piece of pipe on the end of the header collector to try and keep too much air from entering the exhasut manifold.

As far as noise, I know when my V&H megaphone rotted off 50 miles from home. You ever hear those big bore V-Twins with straight pipes that are so ear splitting loud they shake the ground and set off car alarms when they go by? They will sound like sewing machines compared to you. Think offshore racing boats- the ones you can hear from 10 miles away.
 
In addition, the cops are monitoring noise pollution more now than ever in the past.

I could only wish...

It's time for me to pay my property taxes again, up 18% in the last two years. Every time I see some idiot running open exhaust on a bike, with almost no risk of getting a ticket, here's what I'm thinking:

--> Lost revenue.
 
im gonna run the open pipes for now, it may only last a few weeks but i have to see what they sound like....
 
Ran open wheeled "mini-mods" for a few years, 2.3L Fords...at 8000 RPMs, with 180 degree exhaust and open at the collector, the DRONE of the exhaust note would give you a stomah ache in 5 laps...your fillings and crowns would all but fall out of your head! But FUN!!!!! :-D

For some reason though...when I hear the metric bikes with open exhaust, it makes me think....can't afford the V&H...Harley wan't to be...are you going to junk it? :?

And yes, size does matter to the exhaust note...when was the last time you heard a diesel electric train go by with an exhaust note that bothered you? Open exhaust there!!
 
This definitely makes you an anti-social idiot. Congratulations.





Hey, i may be new here... But how about we try and be civil around here. Everyone does what they want any ways. Giving opinions that were requested is one thing... Straight out hounding the guy over your personal feelings is another. Sounds like the anti-social idiot is you. Learn a little courtesy buddy, it'll make life so much nicer. Maybe not for you, but atleast for the people that have to listen to you. :?

Thank you very much. I may be an idiot, but so is the guy in question. Someone has to tell him how antisocial he is.

I really don't care what you say -- the guy is an idiot, and a motorcyclist should be the one telling him that.

I'm out of this thread. I stand by what I said.

so now i am in idiot for modifying my bike a little bit... i want to get the thing on the road. first and foremost. then when i can afford it i will make it better. sorry if you dont like what i am going to do. that doesnt mean i am an idiot.

there is no reason for you to say that.

if i wanted your personal opinion on what kind of person i am, i would ask.

i wanted a consensus on what people thought about open pipes on bikes, not what you think of the owner.

i have what like 30 posts on this forum and now i am getting bashed for something i have not done by some guy called "grandpa"

wow.
 
i would run open pipes just to **** people like you off.

its my bike, i can tear it down to the frame and melt the thing if i want to. that may make me an idiot in your eyes but hey, its not your bike.
 
Do what you want to your bike!!I would like a loud bike but my neighbors would not.If it is just for a little while ...go for it.Another thing to consider is that you might do damage to your bike that way unless you properly adjust for it.I wish I could find a 4 into 1 for my 650.I did have a 750 with no baffel in one side.Its sounded good!!! People are going to ride you for wanting to make a lot of noise.It's personal preference.Just don't go off on them for there concern.They just want to keep a good name for bikers.There is just way to much concern for noise pollution.I hate it when somebody pulls up to the gas pump with there stereo blaring!!!!Personally I wish my bike was louder.
 
GS1000 straight pipes now...

GS1000 straight pipes now...

Go ahead and try it... but I doubt you will like it. A month ago my baffle in my 4 into 1 kerker pipe blew out the back on the highway...I turned around and couldnt find it :oops: . So I got home and thought screw this crappy pipe and unbolted it a little above the collector. I drove it like that for a week thinking its not that bad, however now I cant stand it and dont want to ride untill my new pipe arrives. Its ear splitting at anything over 3000 rpm...when reving it up you can probably here it at least a couple miles away...plus its a little embarrising in public with cars and people around you, I can feel dissaproving eyes everywhere. And I know the cops would definatly stop me if they hered it rev up. While riding it, it feels like the noise is right in your ear instead of behind you like harleys. Anyways try it for now because its hard to pass up riding but lets see how long you last....:-D
 
i want the 4-1 cause i know it will sound great and look a ton better. as soon as i can afford it i will be buying it.
 
well i have the bike running now with the open pipes.... it is very loud but i kind of like it...

i do want to get the 4-1 very soon though cause i need the backpressure on the engine.
 
Hang on I'll stick my head out the window and let you know if I can hear it from Australia.................. Nope it's fine can't hear it from here so it's okay by me. Personally I love 'em loud, sometimes I get woken up at 3am by someone running a multi cyl m/cycle at high revs blocks away and although I dont like being woken at that time of the am it still puts a smile on my face. ..... And I'm a Grandpa too, just not a grumpy ol one that doesn't remember being young. Ride fast ride safe have fun and stay off drugs they'll kill ya.
