Jardine or Vance and Hines?

[gs4evr]

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

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....

[Guest]

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.

Probably made in China now.

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...
