I'm putting on a UPR o/r X-pipe this weekend on my 01GT. The pipe actually comes in two pices. Should I asemple the pipe before I put it on, or should I connect the two pieces to the headers in front first, then to the catbacks, and then connect the one piece in the middle of the pipe? I'd rather just do it right the first time if at all possible....
Thanks in advance.
