Even my exhaust guy questioned why I was doing the full system a year ago

You've just got to take a dump and kill the cat.

the main restriction is the pipe over the diff... I wanted to run full x force with stock rear muffler (might be hard to make it fit) , but I still reckon u will be in the high tens with that combo LU82
