The problem is look at what your getting... from Brayden your getting just a modified bolt on turbo... With a PPE GT40 kit/HTT Promax S300 Kit you get a pedestal, new Down Pipe, gasket kits, Oil Drain tube, oil feed line, v-band clamps and with the HTT you get an intake tube which is a plus. The GT4094 also produces more hp than a Cheetah Brayden has said so himself.
