I have 2 of them one I bought new around the first of the year. The other I bought used from someone here on the site.
The one I bought new I ordered nickle plated. It fit too tight at the exhaust flange, I could have opened the pipe up a bit, but I had a worn exhaust flange so I used it.
The tig welds not that great looking. The rear mount is shiz, the lower mount looks to be cut with a plasma cutter in a Jr. High shop class, and the spring mounts look to be bent from ring shank nails.
Other than that the pipe is great for what I wanted, and that is for the 500 to rev like a 125. unfortuantly the bottom end power is like that of a 125 as well!
If you are racing up oldsmobile hill or something similar, get it. If not don't.

so im guessing this pipe will not bolt onto a 87-88 high pipe Cr500?
if it did that would be sweet.

I like my CPI pipe, I'm not a great rider, but I wanted to feel some of that arm riping power my 88 had.
I know it lost some bottom end but I dont think its bad at all, allready had alot of bottom end, could loose a little. LOL
