I have the Pypes 2.5" with x-pipe on my conv. What I did was lay a 2x4 under the two mufflers and jacked them up so they were level, then clamped the hangers on. Only issue I have is I went with the straight out the back tail pipes and I can not, for the life of me, get them level with the ground. They both go up at an angle. Oh well, time to spend more money for new tail pipes
