Bjorn, my old system also bumped against the leaf springs. If you want run 2.5" pipes over the axle and out the back, its a very tight fit. I think thats gonna be a bigger issue for you than the x pipe. I now have the stock muffler setup, with the pipes fabricated at the shop. He had to use 1.5" going over the axle. Not saying you can't use bigger pipes, it'd just be tough. I'm happy with the new system.
