What ever you do, do not buy it. Took about four hours of work to get it to fit right, and paint doesn't match. Bought a couple things from them, always bad service and quality.
If you are going to buy it you will also need large clamps and epoxy to close up the gap, drill bits, and a turn signal delay.
I just mounted mine and love it it took me about 1 hour and that included taking the tail off and putting it back together. No gaps. The paint color matches but it could have used a little more clear in it. On the bike it looks good. I'll try and post pics tomorrow, I'm at work right now. somebody on Ebay is selling an exact copy of it made of composite and no drilling for a real good price.
Do a search on the site and you'll see different ways guy's are mounting it to get rid of the gapat the tail light.. Mine has absolutely no gap. I removed the tape and used silicone adhesive. Once again I will post pics. Hope this helps.
when i bought mine i wasn't expecting to spend that much money and still have to change it to fit right. paint in still bad quality, looks like it was spray painted by a drunk.
you can look on there also i've replied to people how to get rid of the gap, mine has no gap now. i just feel that an undertail for a bike that practically already has one should should be better quality for the $200 price tag.
i also purchased the front signals for my r6, the first set broke while i was finger tighening the nut. i called them and they said they would send a new set out if i sent the broken ones back. i wan't them on the bike so i purchased a second pair with the agreeance that i would be reimbursed for the first when they received the old ones, so i could get them quicker. two weeks passed by and i called them and they said that i didn't give the all of the credit card info, and they had not tried to contact me. finally got it squared away. not to mention every time i called they would say let me call back within the hour and never call back. so a few weeks later im at the bank and i discover that they've charged me for them again. still not solved said it would be next week for the refund of the now two sets.
not the kind of company i like to deal with, never even once apoligized.
the '04 gixxers have a gap too, but i haven't really paid much attention to them on other bikes. i saw a new r1 with their exhaust/undertail, sounded worst than D&D, although i did't think that was possible. didn't get to get a good look at the r1 though, it was at night going down the road.
