Best place to get a slip on from

Hey everyone I am interested in getting a slip on for a 2006 f4i.  I was wondering what is a good website to order from.  So far I have found that www.pipecity.com is the cheapest.  If anyone knows any other good sites please let me know .... thanks

also check ebay you can get a really good deal

Ridenow.com has clearence items on every once in a while

find the model you like and shop the hell out of it on the internet.    bought mine from devilbikes, they dont distribute to vendors though, so i found what i wanted and they were the only seller.....$449 shipped for a polished highmount.
