Magnapacks are here!!!MAgnapacks are here!!!

They arrived last night. I passed the ups truck on the way home, and I thought I missed him, but he left it on the porch. My wife said i looked like a kid opening a present on christmas day! I was grinning ear to ear as I lifted out the 3.5 in chrome exhaust tips, and I cant wait to hook everything up!! When i pulled out the tips I got to thinking... I saw some posts on here where people were having trouble keeping the tips on their pipes, i guess they kept coming loose and falling off. Anyone ever had that problem?? If so, what is the best way to keep that from happening?? One more thing, anything I should know before the install?? Any help would be, of course, much appreciated!! Thanks guys, in advance...The packs are here-the packs are here-the packs are here....
