eBay Auction LINK
I know its not local, but it does arrive rather quickly. I know, because I just put mine on when I finally mated my Helix catback to my Helix DP [I LOVE IT BTW!!!!!!!!!!]

The eBay seller is 'ScoobieFast' and s/he is a stand-up guy/gal. I accidentally 'bid' on the item instead of clicking 'BIN' and they cancelled the sale for me and just sent me a PayPal request. BAM- I had the package in less than a week.

Also, for the $17.99 price, you get DP CEL fix, UP CEL fix, anti-seize, UP bung-plug [chuckle] and detailed instuctions.

Did I mention FREE shipping?!

$18 is a pretty damn good deal, and I personally like the mechanical deal over the electrical = its less permanent. A similar one made by GP Moto is $30 alone on www.oakosautomotive.com and that is ONLY the DP CEL fix.
