'85 pipes?

[Tharrell]

The modified pipe that came with the bike is on the left.
Looks like a very modified stock pipe.
I snagged the pipe on the right thinking it was a 500 stock pipe but now that I look at it, it appears to be a 250 pipe.
Anybody else think so?
Anyway, pinholes patched, sandblasted and painted with PJ1 hightemp satin.

Damn.
I guess the one on the right truly is a 500 pipe.
The 250 I looked at didn't have the pronounced "S" and then I found this.
Now I wonder about the one on the left.
Apparently it is a later model modified pipe.

The pipe on the right looks exactly like my 87 cr500 pipe.... Without the excessive rust and dents ha

the pipe on the left is a 500 originally, maybee a 1989+ version with the other parts added

the extra bend in chambers ie... 500cc wrap around the gearbox a bit more as abosed to ones that just exit the manifold are as follows

the longer pipe mellows the rate at which the power is delivered .... ive recently purchased a 91 works 500 originating from Europe & it has a different pipe for every track[/img]
