yes once installed you should weld it up so it won't leak. If it leaks before the O2 sensor it won't get accurate readings and it will start dumping in more fuel thus running rich.

BUY THE WELDED! For God sake I cannot urge you to do this enough. I bought the slip fits and they leaked like a B*tch. Once they are installed you cannot simply weld the outside. You must weld the inside where the 4 pipes meet in a star shape (you know what I'm talking about if you've seen them or have them) as well. I learned all of this the hard way. I had to pay to have the headers completely removed, new collectors welded in, and put all back up. Talk about some nice labor charges 
Go with the welded and save yourself a lot of heartache. The slip fit's are only meant for absolute all out race applications where you want to tune the length of where your primaries meet the merge.
