So from what I am gathering, for my factory NPP car I can buy the x-pipe first and install with some minor modification to the inlet tubes on the stock muffler (cut-spread-clamp). Then down the road I can ditch the stock muffler and buy an axle back from you guys and basically bolt it in. And then even further down the road I can buy your headers and bolt them in as well. Pretty cool idea, ill definitely be looking into buying an x-pipe as my next mod if this is how it works.
