for it to seal and not leak it will need to be welded, most exhaust shops will charge around $20 to bend and weld it on for u. Depending on how long of a stack u want. If u do get it welded, it would be wise to dissconnet the battery so the arc from the welder does not fry any of your electrical parts. heres a pic of mine, but its not a stock exhaust.
