Ayone have a website or know "in detail" of how to remove the lower factory resonator box?

 

I did it so long ago I can't remember enough to type out a step-by-step, but it is real easy. You have to remove the air box in the engine bay so that you can remove the connections and bolts that go to the resonator in the fender. Losen all the bolts in the engine bay that would seem to fasten the resonator. Then remove your splash sheild, reach up in the fender and jiggle the resonator. Note whichever bolts in the engine bay move, remove them, and the resonator should just drop strait out.

 

Its a couple 10mm bolts, not a big deal like Dave said. Give yourself some room to work (move the splash shield and intake air box) and it should come out in 10mins.
