Wondering what is what on the stock exhaust, starting at the front? Exhaust manifold, resonators then? cats mufflers? Thanks

manifolds --> front cats --> rear cats --> H pipe (or if L99 a resonator) --> mufflers --> tips

he didnt make it very clear but in the ss manual there are separate h pipe and resonators, and for auto the h pipe is inside the massive resonators

Too bad most of the restriction is in the headers and cats.... replacing everything after that doesnt really do much, and only changes sound if you don't do anything forward of the res.

+1. Replacing just the cats can net you up to 20HP. I replaced my exhaust from the cats back and zilch. Better sound for sure.
