YOu can do that too. tach9 tried that also(do a search) and found that at stock or near stock hp levels changing out the muffs was within a couple of hp of doing a whole cat-back. The larger piping will give a little deeper sound too. If I had my way.... I would want a mandrel bent 2 1/4" cat-back but they don't make one. Try it out and verify tach9's results. I went ahead with the exhaust I got so there is plenty of flow for mods done down the road. 2 1/4" would be perfect.
