does anyone  know if you have to weld it together or doest it come with flanges and gaskets?  im talking about the  95-03 Single Stainless Cat-Back System - #02093515 ... by the way
thank you in advance.
 
 
i'm pretty sure that system is just bolt on.  i have the dual exhaust from Rk and it was bolt on, with no welding required. 
 
 
I have the RkSport single exhaust and it is just bolt on. I recommend having it welded though because the slip joints leak even with the supplied clamps holding them tight. It isn't a major leak but it is a bit noticable.
