Former NXMX5, The kit is the fact that you have a 3 foot mandrel section of pipe and a universal muffler that fits to the factory routing and length and that it comes with 2 additional hangers that mount to chassis bolts. Even if you are capable of doing your own mandrel bending, the homework is done for you and this is a simple, effective installation, that gets the job done for a good price. I don't mind constructive criticism, but ignorant criticism just takes up space on the thread.
