blow off valve, please identify

ok,so i was goin through all my engin crap, in preparation to sell it, and i found on my old motor, what appears to be an aftermarked bov. I cant seem to find any info on it, except that it says prof in blue letters, and looks almost identical to this listing : http://cgi.ebay.com/ebaymotors/JDM-Prof-BOV-BLOW-OFF-VALVE-rx7-fc3s_W0QQcmdZViewItemQQ_trksidZp1638Q2em118Q2el124 7QQcategoryZ33742QQihZ006QQitemZ160229301686QQrdZ1 QQsspagenameZWD1V

please help me identify it, any info would be great.

ok, ive found that it is a japaneese company, and in america it is called sheep dog, but other than that nothing. i wanna find specs, so i kno if its worth it to swap, or if its jus some knock off piece

Almost looks similar to a Turbo XS

so i thought what the hell, might as well install it. Seems to work great. it is slightly louder than stock, but its a bov sound ive never heared before, i think i like it.

Thats the uglyest BOV I have ever seen

well. BOVs arent exactly for looks man, and if you think that is the ugliest bov, then you must not have seen a stock 3s bov, man :P

I did not say it had to be pretty It's just i try to clean stuff up be fore I sell it on ebay you know. Gready makes some pretty kool looking BOV's.

yeah, if it were me selling it i would have. Its a sweet bov tho. Plus im the only person i kno using one. im pleased. it has a very unique sound

If you like it thats all that maters.
