    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I am planning on putting a 4 into one exhaust on my 1978 GS750E, and would like to know which would be the best performance wise, a Jardine or a Vance and Hines exhaust? I plan on rejetting also.
 
I was about to ask same question for my 79 Gs1000L.
I heard the V+H pipes lose the chrome ( and therefore rust) faster than any other mfg.
 
Well, Who do you think is the more performance oriented manufacturer?

V & H of course. They have the track records to back it up.
 
Perhaps you should be looking toward Supertrapp or Yosh... or even keeping it stock :-k

I find this chart hard to believe. It shows all the exhaust brands making less HP at 9000 RPM than they make at 7500 RPM. Something doesn't add up....
 
Unless your bike is jetted for the headers, it might be slower than stock !
 
The biggest performance gain from a pipe is the weight loss. As for hp increase eh. I installed a RC pipe (same as a V&H pipe) and K&N air filer and and to open up my main jets some, that is about it. I also have the Accel super coils on my bike as well.
 
I have a V&H chromed drag pipe. It has been fitted to a katana which has never had the engine run. It is in a shipping container, so the humiddity may be a bit higher than my garage. The pipe chrome is pitted on the down pipes.
this is garbage, and i would not buy another V&H pipe, as it shows how poorly finished they are. Again ,to be clear, it has never been run, but is rusting.

I have thirty year old V&H pipes with not a speck of rust anywhere. Been out riding in rain and snow, not cleaned very often.

Anythng will rust in a crappy enough environment.
 
I have a Star pipe on my street GS. I like the fact it has individual down pipes into a colector then into the megaphone. It sounds awesome. I have a Bob Carpenter "Vasar" drag pipe on the drag bike. Its also a high quality header...
