Superchip it! Best mod for the 4.7 period.

As far as muffler vs no muffler. Youre not really gonna feel much difference either way. it might pull a little better in the higher RPMs without the muffler, but not enough to really make it worth while (noise would be unbearable IMO).

good luck :smileup:

P.S. Ditch the 22s
