Value of a Yoshimura series 1 gs1000/750 (?) 8v 4 into 1 pipe?

[Chuck78]

My buddy just got a GS750 in that has a Yoshimura series 1 4:1 exhaust on it that he is willing to sell me. He thinks after my questioning that it may be a gs1000 pipe.

What do these things typically fetch?

He says it has some dents on the bottom but usable, could use repainted/refinished, & has a non-Yoshi baffle in it.

I'd be using it most likely for a GS750 Rickman 894cc build, but might even make it a GS1000-1075cc Rickman.

Thoughts? I figured $300+, but wasn't sure if these would go into the stratosphere if on ebay.

"dents on the bottom" knocks it out of the "stratosphere" price range. I'd say more in the $200 range if it's clean otherwise.

It's the early Series 1 variety, another local fella said his KZ version of that pipe was similar condition for $500 or $575 I think he said, ebay stratosphere pricing..

I think $400 would be my top dollar as a new Marving upswept 4-1 race pipe (similar but flat collector not traditional 2 on 2 stacked) sells for $475-500 through ExactRep... and I have a Kerker System K aluminum can and MAC (Kerker style) header and a few pipes to fab a mid pipe out of very well/easily.

Still, the Yoshi is alluring but I'm pretty certain if it was on ebay long enough, it'd get into a bid sniping frenzy and go for $375-450. I'd gladly pay $300 for it needing minor dent repair (very usable as is though) and repainting. I wouldn't go over $400-450 though, as the Marving S/07/BC is really really sweet. But for a Rickman CR powered by a GS750-894cc or a GS1000-1085, and equipped with vintage Yoshimura Isle of Man POPY race cams, this vintage piece seems even more appropriate. Vintage Fox Factory Superbike Shox as well, piggybacks. A very functional assembly of vintage speed parts with the only modern clues being the hayabusa 6 pot calipers and cbr900rr rotors up front. Rickman/AP Lockheed rear brakes.

The earlier versions of Yoshimura pipes didn't have the welded on tag on the tail pipe. The early Yoshimura pipes had no labels at all. I think it's a post '82 vintage system. If you look at the bottom of the collector you should see a stamped part number; 110 for 1100, 100 for 1000 and 75 for 750/850.

The megaphone styling puts it pre 80, like mine.

80 and later pipes had a smaller mid pipe and collector, then a "potato" like muffler

Can you post up a shot of the logo? Mine is missing

Value? You're probably about right at $300 if the bottom is just dented and not smashed

 

[rudeman]

What megaphone? That's a straight pipe, same diameter from the collector back. The only megaphone pipe I've ever seen from Yoshimura were the 4-into-2 systems they produced in the early '80s.

Heli-arc or possibly bronze welded on tag apparently indicates the earlier versions, series 1.






This thing will fit darn near perfect on the Rickman, very nicely tucked in, & it really looks like somehow the Yoshi exhaust hanger might even line up with the Rickman, wow...

Also, I can't believe how light this thing is. Extremely light. Came with a brand new baffle even

For those not familiar, Great Britain outlawed fiberglass gas tanks in the 70's, so Rickman had their in-house expert fiberglass shop make a beautifully crafted fiberglass tank cover instead of a full tank, to slip over top of these basic steel fuel cells underneath. Instead of hiring more skilled craftsmen to make sheet metal tanks... mine was missing all the fiberglass
