Flowmaster X kit vs Pypes X kit, any experience with fitment?

I installed the pypes system the only problem was with the X pipe. I had to use my floor jack to spread them apart in order to bolt up to the collectors on the headers. Just recently i changed headers to tti’s and had to remake the pipe that go to the collectors. Other than that I am pleased with them. I would also recommend some better pipe hangers. The ones that are supplied work ok but they move quite a bit.
