Lpp headers. What y-pipe?
Or get the LPP x-pipe if you don't mind having dumps

Here is a great Y-pipe: http://www.mufflex-performance.com/fbody_8.html
But it's made for Hooker longtubes so it might take some work to make it fit on the LPP headers. But if you can get it to fit on your headers, it would hook up great to the 4" catbacks Mufflex sells
