Yup you can buy a 3 inch pipe at a angle then cut it up as you need.. I cut the flex as well as the flanges off the rear and brought just the rear header to one of the local exhaust shops and had him bend me a pipe close to the angle of the jig.. I still had to cut it quite a bit but it was a good starting point.. Installed the rear from the top.. Mocked up the angle for the piping then took it all off and had it tacted in place. Brought it back home..threw the header back on and measure the existing length of piping that I needed to connect to the resonator and and threw in the new flex pipe as well as a cat then took everything back off and had it fully welded. Yea it took a bit more effort but a) cars not registered b) wanted it done this way. If the flex or cat ever needed to be replaced it simple to remove and replace and no need to mess with taking the rear header off again.
